Connection diagram for two switches. An effective diagram for connecting a pass-through switch from two places
The lighting in the room should not only be comfortable, but also easy to control. This can be achieved through the installation of electronic control systems such as a smart home, that is, by introducing a variety of timers and sensors - or you can use old-fashioned methods.
Unlike newfangled solutions, they are easy to implement and quite affordable. Therefore, their implementation will not result in a lot of problems and an “empty” wallet for you.
One of the oldest and most proven schemes is the method of using pass-through and crossover switches. The price of such switches is not that high, and the connection diagram, although it seems very complicated at first glance, should not cause you any problems.
Through and cross switches
But before moving directly to the connection diagram, let's figure out what these pass-through and crossover switches are, and how they differ from the lighting switches we are used to.
|
|
To make things easier to understand, let's look at a regular switch. It has two contacts, let's call them 1 and 2. When the switch is in the on position, these contacts are closed. When the switch is turned off, these contacts open. |
|
|
Now let's take the pass-through switch. It already has three contacts - 1, 2 and 3. When the switch is in the on position, contacts 1 and 2 are closed. Contacts 1 and 3 are open. When such a switch is turned off, contacts 1 and 2 open, and contacts 1 and 3 close. |
|
|
As you probably already guessed, the crossover switch already has four contacts - 1, 2, 3 and 4. In the on position, contacts 1 and 3, as well as 2 and 4 are closed. When the switch is turned off, they open, and contacts 1 and 4 are closed, and also 2 and 3. |
Note! Such switches can operate at a rated network current of 6, 10 or 16A. In this case, all switches in the circuit must have the same or greater rated current. And the wires used during installation have the same cross-section.
Connection diagram for pass-through and cross switches for lighting control from 4 places
Having an idea of the design features of such switching devices, you can begin to consider their connection diagram. By the way, it is correct to call such switching devices not switches, but switches.
So:
- Any lighting control from 4 places requires the installation of four switching devices. Cross and pass-through switches for hidden wiring are installed in ordinary embedded boxes. You choose their installation locations based on expediency.
- Pass-through switches must be the first and last in the circuit. Therefore, they are mounted at extreme points.
- Now let's proceed directly to the connection. Let's start by connecting the first pass-through switch. From the distribution box, as with a regular switch, you take a phase wire. It should be connected to pin one. Usually it can be determined visually.
- From the other two contacts of the first crossover switch, you install a two-wire wire to the first crossover switch. This can be done through a connection in the junction box, or by connecting directly to the switch contacts. They should be connected to pins 1 and 2, as in the video.
Note! Our designation 1 and 2, 3 and 4 is very arbitrary. Each manufacturer independently designates pairs of contacts. But usually one pair of contacts is located in the upper part - conventionally 1 and 2, and the second pair of contacts - 3 and 4 is located in the lower part.
- From pins 3 and 4 of the first crossover switch, we run a wire to pins 1 and 2 of the second. From pins 3 and 4 of the second crossover switch, we run a wire to pins 2 and 3 of the second pass-through switch.
- Now all that remains is to connect pin 1 of the second crossover switch to the lamp. That's it, connecting the switches is finished. All that remains is to connect the neutral and protective wires to the corresponding contacts of the lamp - and our circuit is ready for use.
As you can see, connecting this circuit is not particularly difficult, and it can be done with your own hands. At the same time, when installing the entire circuit through one junction box, even experienced electricians can get confused.
And a large number of contact connections does not add reliability to the circuit. Based on this, recently this scheme has been used less and less. After all, there are simpler options.
Lighting control circuit from 4 places using a pulse relay
One of these simpler options is the use of so-called pulse relays.
They began to be widely used in the domestic sphere relatively recently, but the relay itself has been known for a long time and has been successfully used in production. It has proven itself quite well, and its use for lighting control is quite justified.
What is a pulse relay?
Now let's figure out what this impulse relay is, and what type of lighting should be in the room to use it? Pulse relays come in two types - electromagnetic and electronic. We will look at the principle of operation using an electromagnetic relay as an example, since it is more clear.
- Like any other relay, a pulse relay has a coil and a magnetic circuit. The magnetic circuit is open in the normal position.
- When voltage is applied to the coil, the magnetic circuit closes. Due to the fact that movable contacts are rigidly attached to the magnetic circuit, they also move and close with the stationary contacts.
- But in a conventional relay, when the voltage on the coil disappears, the magnetic circuit disappears. As a result, the contacts also open. This does not happen in a pulse relay, since the contacts are blocked in the actuated position.
- In order for the contacts in the pulse relay to change their position, voltage must be reapplied to the coil. At the same time, they will also be locked in the off position.
- To apply voltage to the coil, ordinary buttons are used. After all, to switch the relay from one position to another, a pulse of up to 0.3 seconds is enough. In this case, it is possible to use such a relay for almost any lighting system. So Led lighting can have a total power of up to 460 W. But the number and power of fluorescent lamps in the circuit depends on their cosα, and can vary from 8 to 25 pieces.
Lighting control circuit from a pulse relay
Well, connecting a pulse relay is an order of magnitude simpler than a circuit with pass-through and crossover switches. But here you should be careful not to confuse the connection points.
Since each manufacturer marks the output of a pulse relay differently, we will take the most common model RIO-1 as a sample.
- Since our buttons only switch the relay coil circuits, we’ll start by connecting the power part of our relay. To do this, we connect the cable to the phase group wire, which we connect to contact “11” - this is one power contact of our relay.
- From the second power contact of the relay - “14” we connect our lamps. In addition, for the lamps to operate, we need to connect an additional neutral and protective wire to them. This should be done in accordance with the labeling.
- Now our instructions will tell you how to connect the relay coil. To do this, we need four push-button switches that have pins 1 and 2. Which one will be the first and which one will be the second is not important.
- From the same phase group wire, in the distribution box we connect a wire that we mount to all contacts number 1 of the buttons. Then we connect all contacts number two, and connect them to the “Y” contact of the pulse relay. For normal operation of the coil, all that remains is to connect the neutral wire to contact “N” of the pulse relay - and our circuit is ready for operation.
Now, when you press any of the buttons, voltage will be applied to the relay coil, and it will transfer the power contact. It will close and the light will come on. When you press any button again, voltage will be applied to the coil again and it will open the power contact. The light will dim accordingly. And so on an infinite number of times.
Conclusion
Lighting design should always include the preparation of the most convenient control scheme. We have presented the two most commonly used schemes.
But there are also other options. Therefore, if for some reason this or that scheme does not suit you, then you will certainly find a more acceptable option for you both on our website and on the Internet.
Proper control of lighting fixtures will help and simplify their operation. If you install the pass-through switch without errors, the 2-point connection diagram will perform its functions flawlessly. This article discusses the issues of choosing suitable products and installation work. Having studied this information, you can independently implement the project at a convenient time and at reasonable costs.
After training, it will not be difficult to create a convenient lighting control scheme
If there is a flight of stairs at home, then its lighting can be conveniently controlled from two places. Automatic turning off of the light when leaving a certain area can be organized using timers or sensors that record movement. But such electronic devices are expensive. They are more complex and less durable. They can be damaged by vibrations and high levels of humidity.
The circuit of a pass-through switch from two places is simpler and cheaper. Any thrifty owner will appreciate the following features:
- High reliability and low cost of a standard product.
- Easy to install and no complicated settings.
- Immediate power shutdown if necessary and optimal energy consumption.
- Possibility to carry out repair work yourself and no costs for the services of experienced specialists.
Such solutions are useful in large houses and small apartments. Light control devices are placed in the hallway, near the entrance and bed in the bedroom, and in different places in the living room. You should start by accurately identifying user needs and drawing up a corresponding list of tasks.
How a pass-through switch functions: 2-point connection diagram
A conventional switch breaks and connects the electrical circuit of the phase wire, which is designated by the Latin letter “L” or “F”. This action supplies power to the connected device. The second conductor (neutral, “N”) is necessary to create a closed circuit through which current flows. The third wire (special designation “Ground”) connects the instrument housing to. This connection prevents electric shock due to short circuits and ensures timely operation of circuit breakers.
The operating principle of transition-type devices can be studied in the following picture.
In the indicated position the contacts are closed. Current flows through the circuit and it lights up. If a person moves to another switch and presses a key, the key will move to the "3" position. The circuit will be broken and the lamp will go out. Now it is enough to turn on the key on either side to reapply voltage.
Preparation for project implementation
You will need a cable for installation. Its parameters are selected taking into account maximum power. With a copper core cross section of 1.5 mm and a 220V supply network, it is permissible to connect lamps with a total consumption of up to 4 kW. Smaller sizes are not recommended in order to maintain high mechanical strength and ensure a good load margin.
To ensure that connecting a pass-through switch according to the diagram from two places does not cause unnecessary difficulties, you should purchase wires with different color markings:
- Grounding is a combination of green and yellow. It is connected to a special bus, which is installed in the central distribution panel of a private house or apartment.
- A blue sheath is used when choosing a “zero” wire.
- There are no special requirements for the color of the phase wire. But it is better if it does not change in different sections of the wiring.
Wires combined in a single cable with double insulation are suitable. As a rule, solid cores are used. In modern products of this type, the outer layers are created from polymers with special additives. The following abbreviations confirm the special properties of the shells:
- NG – non-flammable;
- FR – increased resistance to open flame;
- LS – low smoke emission during combustion.
This table shows the characteristics of pass-through switches for a 2-point connection diagram:
| Image | Trademark, series | Peculiarities | price, rub. |
|---|---|---|---|
 | IEC QUARTA | Beige color, set with frame, body and frame made of ABS plastic. | 90-95 |
| ABB Decento | Champagne, with frame. | 864 | |
| Legrand Etika | White, frameless, with reinforced construction and cable fixation with screw connection. | 120-130 | |
| Legrand Etika | Similar to the previous version, but in ivory finish. | 130-140 | |
| ABB Cosmo | Built-in lighting. | 150-160 | |
| Schneider Electric GLOSSA | Aluminum color | 155-165 | |
| Legrand Quteo | For outdoor installation. Waterproof device in accordance with IP44 class requirements. | 220-240 |
Important! From the reference data it is clear that the cost depends on the brand, aesthetic and functional parameters. All products shown are rated for 10 A current.
To perform work operations you will need:
- Phillips and flat head screwdrivers.
- Knife and side cutters.
- Construction level, tape measure.
- Screwdriver probe with built-in phase indicator.
Tools and consumables for laying channels are selected depending on the characteristics of the structure. The most difficult thing to work with is wooden houses. To prevent emergency situations, the following techniques are used:
- installation of cables in steel or copper pipes;
- open installation.
Hiding conductors in corrugated polymer and metal tubes is prohibited. Such engineering systems must comply with the standards of PUE and PTEEP. Special channels are created in non-combustible brick and concrete structures. Depending on the material, the appropriate tool and attachments are selected.

Step-by-step installation of a pass-through switch connection diagram from 2 places
The following instructions will help you perform all operations correctly:
- Remove wallpaper, cladding panels and other decorative coatings. Marking of future lines is applied.
- The grooves are laid starting from the shield. A free distance of at least 50% of the cable diameter is left to the walls of the upper edge of the channel.
- Horizontal lines should be at the same level.
- Cable laying is done carefully. Necessary fixation with nails of suitable sizes prior to plaster without damaging the protective shells is acceptable.
- Switches and distribution boxes are installed. The conductors will be connected to the appropriate terminals.
- The assembled products are inserted into plastic mounting boxes. Using built-in mechanisms, pointed elements extend to ensure secure fastening.
- The functioning of the system is checked. If there are no comments, the channels are closed with cement mortar. The frames are installed after the walls have been restored.
Solving other problems
Below are examples of how to connect a pass-through switch using other connection diagrams. Having understood the principles of operation, it will not be difficult to modify the project yourself, taking into account your personal requirements.
Control of two lamps
If necessary, you can organize independent control of two lamps. The corresponding connection of the lamps is shown here. Please note that you will need to purchase two-key switches.
Controlling two lamps
Turning lights on and off from multiple locations
The following pictures indicate how the devices are connected if the standard connection diagram for a two-key pass-through switch is not suitable.
In order to properly use the pass-through switch, a 2-point connection diagram is created based on the needs of future users. The plan includes consumables, construction and finishing materials, tools and fixtures. The exact choice of channel laying technology is important. The electrical parameters of certified switches are identical. But the appearance and additional capabilities of these devices have a significant impact on the cost.
How to connect a pass-through switch (video)
One of the most common tasks faced by a residential electrician is the installation of one or more lamps. Usually this does not create any problem, because connecting one switch is quite simple. But often you need to make sure that the light bulb turns on from several places, for example, from two, more - less often. In this article we will look at lighting control schemes using multiple switches.
Light control from two places
This task is often found in private houses in the backyard, for example, near the front door and gate, at the entrance to the yard, as well as in houses with several floors, so that it is possible to turn on the light from any of the floors and safely go down the stairs.
The main problem is that if you install two regular switches on one lamp, then no matter how you connect them, either they must both be on, or both must be off. Therefore, it will not be possible to fully control lighting from several places using this scheme.
In order to solve this problem use . It would be more correct to call such a device a switch. Let's look at the circuit and features of the pass-through switch.
Here we see that the internal circuit of the switch differs from the usual one. If in the standard version the contact is either closed or not, then here the moving contact closes either to one line or to the other, which is why I called it a switch.
If you still don’t understand how this circuit works, let’s look at its states:
1. On both switches, the key is pressed to the “UP” position - the light is on, the current flows through the “upper” wire (if you look at the diagram above).
2. The first switch is in the “DOWN” position, and the second is “UP” (or vice versa) - no current flows through the circuit, the lamp does not light.
3. Both switches are in the “down” position - current flows through the “bottom” wire and the lamp lights up.
The circuit is quite simple to assemble:
1. We directly connect the neutral to the lamp from the junction box or in another way, depending on the circumstances
2. A three-core cable is pulled to the switch closest to the power source (let’s say a 220V network). We connect the first core to the phase and the middle moving contact of the switch. Below we present the switch terminals and its diagram again.
3. We connect the two remaining wires to a pair of output fixed contacts and a second switch.
4. From the middle moving contact of the second switch we take the outgoing phase and connect it to the lamp.
The pass-through switch differs from the usual one in that it has a switching contact; in total, it has three terminals for connection instead of two. They also come in one, two and three key versions. Then this circuit is simply duplicated in accordance with the number of keys and groups of lamps as shown in the figure below.
Interesting: If you have the opportunity to connect the neutral phase to each of the switches with minimal cable waste from different distribution boxes, you can use an alternative version of this circuit. It differs in that the light bulb is connected to the moving contact, and the phase with zero is connected to the stationary ones and, as it were, is mirrored.
How to mount
For ease of installation, you need to imagine in advance how you will lay the cables, what is closer to the first switch and what is closer to the second - a distribution box with an incoming phase or a lamp, or maybe both... But in most cases you need a simple three-core wire or cable, Depending on the operating and installation conditions, the following are suitable:
PVA 3x0.75…3x1.5;
ShVVP 3x0.75…3x1.5;
Or a foreign analogue of NYM with similar sections.
You can use the cores from these wires separately, or you can also buy a single-core wire of the PV brand, the appropriate flexibility class, for example, PV-1 - this is a rigid monolithic version. In this case, the likelihood of error will be reduced, especially if you choose multi-colored cores. The picture below shows one of the installation options in a more visual form:
Control from three or more places
If you need a lamp to be switched on from three or more places, cross switches come into play; they are sometimes called intermediate switches. The diagram is shown below.
Beginners may be intimidated by the three-place light control scheme, but let's understand it. A cross switch is the same pass-through switch with only one key that simultaneously switches two groups of contacts. The only difference on the visible part is that the cross has 4 terminals for connecting wires, and the through has 3.
Why is a cross switch needed? Then, in the lighting control circuit from two places, the pass-through switches are connected by two wires, and due to this, the desired power line of the lamp is selectively connected. Here you also need to switch this pair of wires with each other; for this, use a cross switch.
The logic of the circuit is simple, let's figure it out, just for brevity let's designate the switches as A, B and C, from left to right according to the circuit.
1. All three switches are in the “up” position - current flows along the red line and the lamp is on.
2. Switch “A” is in the “down” position, the rest are “up”. Then the phase is applied to the blue line, and the lamp is connected to the red line - no current flows. If you switch the switch “B” - “down”, the lamp will light up, because the current will flow along the red line in the diagram, the same thing will happen if you switch “C”, only the current will flow along the blue line on the diagram.
The remaining provisions are similar.
Assembling a switching circuit from three places is quite simple. We connect the phase to the middle contact of one of the outer pass-through switches, and from the second pass-through switch, from its middle contact, lay a wire to the lamp.
From the first pass-through, in any sequence and to any terminals, we connect to the cross-connect, and, from its second pair of terminals, two wires to the other pass-through. This connection is shown more clearly in the figure below.
Further increase in the number of switches to control one lamp occurs simply by adding cross switches to the gap. Below is a diagram of light control from 4 places.
The same scheme, but for control from 5 places:
Conclusion
Controlling lighting fixtures from different locations is a very convenient option for long corridors, staircases or galleries. Indeed, it is not pleasant to come home, turn on the light downstairs, go up to the room, and then go down again to turn off the light. In this case, the return path will have to be overcome in the dark. It is much more convenient to turn it on at the beginning of the stairs, and turn it off at the end, and the same in the opposite direction. It is for such situations that pass-through switches (PB) are used, which allow you to control lamps from several points independently of each other. In this article we will tell you how to connect a pass-through switch and present step-by-step diagrams.
Connecting pass-through switches: step-by-step instructions
The devices in question do not have a neutral position to ensure a break in the electrical circuit. They are capable of directing the flow of electricity in one direction or another by closing different contacts. Therefore, the principle of their operation is based on their performance as limit switches, changing the state of the electrical circuit at different parts of its length. Moreover, they do not duplicate each other, but work autonomously, although they are elements of the same circuit. In addition to ease of use, this control method saves energy. Read also the article: → "".
The use of pass-through switches makes available equipment for lighting networks consisting of one or more lines and controlled from two or more points. Each connection option will be considered schematically and described step by step, which will allow the user to evaluate the advantages of this connection system and make the switching independently.
Control scheme from two places
This is the simplest method, which involves installing two single-key devices on different sections of the route (corridor, stairs). All connections are made only on the phase conductor and its branching between two PVs. The neutral wire is sent directly to the consumer; it does not take part in the connection process. The switching method is indicated in the diagram:
A simple diagram for connecting one lighting line using two PVs The step-by-step wiring procedure can be described as follows:
- Each pass-through switch has terminals 2.3, between which the flowing current is distributed. The terminals of both devices are connected to each other
- The central input of the first PV is connected to the 220 V phase wire
- The second PV is switched with the consumer.
Thus, each of the devices can close or open a circuit depending on the position of the contacts relative to each other.
Practical advice: wiring can be done in two distribution boxes located near each of the switches, or in one box mounted in the middle of the line. The second method may seem more attractive, but in reality it will require a longer length of wires, as well as a larger number of twists in one box.
General view of the parts of the electrical circuit of the lighting network in assembled condition Control circuit for two lighting lines
With this arrangement, two-key products are used, in which each of the keys performs switching operations on one of the lighting lines. Read also the article: → "".
The connection process can be presented in step-by-step instructions:
- The phase conductor is connected to the input terminal of the first pass-through switch, where it is connected to the second input using a jumper
- The terminals of the outputs of both supply voltages are connected to each other in pairs and correspondence to the device keys
- The input terminals of the second switch are mounted each with its own wire of the lighting line (lighting device).
The neutral conductor is common to both lines. Thus, each key of the device controls its own electrical circuit in one of the sections, turning the light on or off.
Connecting two lighting lines using switches with two keys Three-seat control scheme
The uniqueness of this system lies in the ability to control lighting through three circuits. It includes an additional device, which, according to the principle of operation, is pass-through, but unlike the previously discussed models, it has two inputs, two outputs and a paired moving contact operating between three fixed ones. This element is called a cross switch. It is installed in the third section, from which the light is turned on and off.
To draw up the circuit, two single-key switches, one cross switch and two distribution boxes are used. The step-by-step connection process will look like this:
- The 220 V network phase conductor is connected to the input of the first PV
- The second PV input is connected to the lighting line
- The outputs of both pass-through switches are connected to the corresponding outputs of the crossover device.
The wires are connected in junction boxes, of which there can be two (as shown in the diagram) or three.
Connection diagram for pass-through devices with socket
To create a network of lighting devices with the ability to turn on and off from several points, you can use an L-conductor from the old lighting line as a phase, connecting the input of the first PV to it and then wiring according to one of the above methods.
Appearance of a block combining a socket and a power source in one device In the case of installing a new circuit, the phase wire can be removed from the nearest outlet or its conductor can be found in the junction box by testing.
Also, one of the simple options is to install a switch-socket unit, which always looks solid and is very practical in everyday life.
An ordinary wire with a metal core corresponding to the material of the electrical wiring and not exceeding its cross-section should serve as a jumper between the socket phase and the switch. The wiring between devices and distribution boxes is carried out either hidden, in a groove under a layer of putty, or by laying it in cable channels.
Selection of pass-through switches
The choice of devices for controlling lighting fixtures depends on the connection diagram, the number of points and the personal preferences of the user.
In addition, products can be divided according to the method of installation into mortise and external (overhead) models. Devices are also distinguished:
- mechanical, operating by pressing;
- sensory, triggered by a light touch;
- remote, operating from an infrared remote control.
Remote models are most often used in large living rooms or spacious offices, where it can be useful to control lighting lines from anywhere in the room (leave one of the lamps or turn on all of them at once). Read also the article: → "".
Manufacturers of walk-through switches
Online stores vying with each other to offer electrical goods from different manufacturers, among which you can see products from well-known brands and products from unfamiliar companies. Users are offered a comparative analysis of some brands of domestic and foreign manufacturers, the purpose of which is not to give ratings or advertise one of the companies.

The information provided is the average market value of the models of these companies and cannot reliably reflect the overall picture of the price values of all goods. The cost of a product depends on its functionality, materials used and brand recognition. For example, Legrand Valena and Schneider Electric are well-known brands all over the world. Their products are of high quality, which is confirmed by the warranty periods provided by the manufacturers.
Mistakes made when installing pass-through switches
Among the mistakes made by novice electricians, the most common ones should be noted, which can affect the quality of work on installing and connecting devices to control lighting fixtures from several places.
- Trying to make all connections in one junction box. This option is possible when switching a simple single-line diagram with two devices. For more complex connections, the connection sections should be separated into two or even three boxes to avoid a large number of twists in one place. Otherwise, it may result in a short circuit due to insufficient insulation and difficulty in subsequent maintenance or repair.
A large number of twists in one place can lead to a short circuit and complicate repairs - The use of wires with different materials of current-carrying cores. Such a connection is unacceptable, because during operation oxidation will certainly occur and contact will be lost.
- Installation of splices in the cable channel gutter or under a layer of plaster for hidden wiring. This can lead to electric leakage due to insulation failure as a result of the wall getting wet or condensation accumulating in the box. As a result, current may break through to the wall or permanently trigger protective equipment (RCD).
- Incorrect design of connections when connecting wires. The twist must be tightly tied and have a length of at least 25 mm. Under this condition, the contact will be reliable and durable. And the most correct solution would be to use terminal blocks.
Practical advice: When insulating a joint, it is better to additionally put a protective cap on top of the insulation. This will provide better short circuit protection.
Current questions on the topic
Question No. 1. Is it possible to install pass-through switches without inserting wires into distribution boxes?
This is quite real. Boxes are needed to supply a phase to the first device and direct the wire to the lighting fixture from the last. The rest of the switching between devices can be carried out in single pieces of wires from terminal to terminal. If the wiring is hidden, the overall appearance of the room will not be affected. If the wires are placed in a box or corrugation, then an unsightly cable will stretch along the entire wall.
Question No. 2. Why, instead of a complex system of installing pass-through switches, not use motion sensors that will turn on the lights in the corridor when there is movement and turn them off when there is no movement?
This is indeed possible, but there are some circumstances that argue against such a solution. The first reason is high cost; motion sensors are much more expensive than switches. The second is an inconvenience; if for some reason the user stops, the light will go out. The reasons for stopping may vary. It's good if it happens in a narrow passage. What if it's on the stairs? Now imagine a huge office where people need to constantly move in order to keep the lights on, instead of concentrating on work. You can, of course, install a backup switch, but then the whole meaning of the plan is lost.
Question No. 3. If there are switches that work with a remote control, then why not install such a device at one end of the corridor, and put a remote control at the other end so that you can turn it on or off if necessary?
This would be too simple a solution if the remote control did not require power. As always, the batteries will run out at the most inopportune moment. In addition, the range of any emitted signal is limited, which means that the remote control is not suitable for every situation. Not all rooms, and especially stairs, have a rectilinear shape. The remote control is ineffective in these cases.
In conclusion, it can be noted that the use of pass-through devices, although it can cause some confusion associated with their installation and connection, will in the future only bring comfort and ease of use. Therefore, the number of users who have decided in favor of positive changes is constantly increasing.
To increase the operating comfort of lighting fixtures, walk-through lighting fixtures are used, which allow you to control room lighting from two or more places. Sometimes this is not only a convenience, but also a necessity.
Most often, the connection diagram for a pass-through switch from 2 places is used in the following places, namely:
- . By installing switching devices on the 1st and 2nd floors, you can turn on the lights, go up or down and turn off the lights. In houses with more than 2 floors, additional devices can be added to the scheme;
- . One switch is installed near the door, and the other device is installed near;
- . Switches are installed at the beginning and end of the room.
This list can be kept for quite a long time, since each case has its own option for using pass-through switch systems. To save time and money, all operations can be performed independently, subject to the recommendations that will be given in this article.

What is a pass-through switch and its difference from a regular switch
A pass-through switch is a device that allows you to control one light source from two or more places. The schemes for connecting them to the electrical network are a little more complicated than, since it involves the installation of several switching devices.
Lighting with pass-through switching devices, as a rule, is mounted on, in, long and garden. Such a scheme makes it possible to turn on the light in one place and turn it off in another, without resorting to the first switch.
To understand how a switch differs from a switch, you must first define the terms.
Lezard
The Chinese manufacturer Lezard is part of the Legrand company, but only the stylish design remains from the native brand, and the build quality sometimes suffers from failures. But for such a price the quality is appropriate.
Wessen

When installing switches, it is necessary to ensure that there is no electric current using an indicator.
The most convenient height for ease of use is considered to be 900 mm from the floor. It is better to place the switch at a distance of 200 mm from the doorway.
If the device is installed outdoors, you should purchase switches with a protection class of at least IP44.
Before installation, you first need to use an indicator to identify the phase wire and mark it. This will make it easier to further connect the pass-through switch.
