Wiring diagram of a pass-through switch with 2 places: how to organize system control

Often there is a need for "pass-through" lighting. We are talking about stairwells and long corridors now. Indeed, in the dark it is difficult to move around such rooms, and the lighting that is constantly on is a big waste of electricity. And how convenient is it to turn on the light when entering the corridor, and turn it off at the exit? But here the question arises. After all, if the switch is turned on at the entrance, then it will not be possible to turn it off at the exit ... The solution here will be the equipment that appeared on our market relatively recently, which will be discussed today. The wiring diagram of a 2-way switch is not easy, but now we will try to figure it out.

The pass-through switch can be recognized by the arrows on the key

But at the cross switch, the arrows are located horizontally

What is a pass-through switch and how is it different from a conventional one

Let's start by defining these concepts:

This is the circuit for switching on such devices

But if now it is clear how the switch differs from the switch, then you should think about what the adapter is. In general, his device is something in common between them. Although, if you think about the question "checkpoint switch - what is it", then we can say that it is more of a "switch". And in order to more fully understand what its principle of operation and device are, let's try to understand this in more detail.

What is the working principle of the tunnel

At first glance, the operating principle of the pass-through switch is simple. A person enters a darkened corridor or a flight of stairs and turns on the lights. Further, having passed the required territory, with the help of another switch, he turns off the light. In this case, these actions can be repeated both in the same order and vice versa.

If we consider in general terms the device of pass-through switches, then we can say that it is a little more complicated than that of conventional ones. For example, before their appearance, magnetic starters were used from several points to perform such a function, which have a higher price, are too overall, and besides, they emit some hum during operation.

The simplest circuit for connecting a pass-through switch

In terms of the scheme, such switches are similar to two-key switches. This means that in principle a double switch can be used in this capacity. The only disadvantage here is that the two-rocker switch can be used where a one-rocker switch is used. Hence the conclusion that the bushing saves space and time spent on installation.

Let's try to understand the essence of the work that needs to be done for the independent manufacture of such a device, as well as some of the nuances of its connection.

How to make a pass-through switch from a conventional one and its connection diagram

Before you make a pass-through switch from a conventional one, you need to understand the method and diagram of its connection. Looking at the circuit for a simple two-key breaker, you can see that it has one input and two output terminals. Then a pair of breakers in the circuit must be mounted as if in a mirror image. The phase input goes to the input terminal of the first, the output contacts of both breakers are connected to each other by two separate wires. Well, already the input terminal of the second switch is switched with the consumer. In this case, zero goes directly to the lamp.

But three-key switches can be without arrows. In this case, you need to look at the number of contacts

Wiring diagrams of various types of pass-through switches

Such equipment, by analogy with conventional breakers, can be:

There are also more complex types, but today we will not talk about them due to their rather rare use. Let's try to figure out how to properly connect the pass-through switch using some tips and instructions.Also, photo illustrations will certainly help the dear reader. After all, when actions are clearly shown, installation is much easier.

One-button switch wiring diagram and complete installation instructions

The essence of the operation of the single-key cross-switch itself is probably already clear. Therefore, now we will consider step by step how it is mounted using illustrative photo examples.

Photo	Description of work
	When open, a one-key switch looks like a regular two-key switch. The illustration shows the output contacts (top), and the input (bottom).
	The downside requires additional clarification. The Latin letter "L" denotes the input of the phase wire (or its output to the lighting device).
	The numbers 1 and 2 are the connection of the breakers to each other
	This is a diagram of how the device works. It is by this marking that you can determine that this switch is a checkpoint.
	We start assembling the first one. As usual, by color coding, we commute the white phase wire to the input terminal
	We hook the remaining two to the output contacts. At the same time, their color does not matter - here you can use the yellow-green wire, as it happened in our case. The second switch is mounted in exactly the same way.
	We pass to the junction box. The first step is to connect the lead wire zero to the lamp zero. In our case, special “Wago” terminal blocks are used for commutation. This method is more convenient.
	The grounding coming through the lead-in cable can be removed to the side if not in use. If land is needed, then it also goes directly to the consumer.
	The phase from the supply cable (white wire) goes to one of the switches. Which one is not of fundamental importance. After all, they are connected identically.
	From the second switch, the white wire will go to the lighting fixture.
	It remains only to connect the remaining wires coming from the color breakers to each other. With this we will provide a connection between them ...
	... and by supplying power from the switchboard, check the operability of the entire mounted circuit.

Thus, it becomes clear that there are no particular difficulties in the installation of the single-rocker switch.

The nuances of the connection diagram for two-key pass-through switches

First, let's figure out in which case two keys may be needed. It's pretty simple. For example, there is a flight of stairs in 2 floors. Why turn on the light for everyone, if you can turn on the light from below on the first floor, after going through it, switch the lighting to the second, and then turn off everything there. After all, the savings in electricity in this case will be greater. It is the same in an ordinary corridor - why do you need full, bright lighting, if there is a possibility of turning on only the emergency light.

Installation here is a little more complicated - after all, each of the switches no longer has 3 contacts, but 6 contacts. This means that the cable cores going to them need 2 times more than in the previous case. That is why it is important not to get confused when wiring the junction box. Otherwise, all actions are the same. If you think about it, the installation of a pair of such switches can be compared to the switching of four one-key switches.

The connection of the double pass-through switch is made as follows.

Photo	Action being performed
	As you can see, there are six contacts in such a switch. It has 2 3-core cables. The terminal markings show that there are 2 sockets for the phase conductors, designated as “L1” and “L2”
	Terminals 1,2,3 and 4 are intended for switching switches
	It should be noted that the remaining 2 cores of the wire, the phase of which goes to “L1”, must be connected to terminals 1 and 2 ...
	... The same goes for the second cable.
	In order not to get confused later, it is better to mark both sides of one piece of cable with colored electrical tape. The second can be left as it is
	Another switch is mounted completely identical, the wires are also marked (in our case, green tape)
	Be sure to check the lack of power on the incoming wire, through which it will subsequently be supplied
	First of all, we connect the incoming zero with both light sources.
	Now the incoming phase is spread over both feeds of one of the switches. What does not matter
	Then we work exclusively with the outgoing wires, pairing the switches according to the color coding. Don't forget about cables marked with electrical tape.
	Having completed this work, it remains only to connect the white wires that have come out of the second pass-through each with one of the lamps and apply power

As you can see, there is a certain difficulty in this work, but still it is quite doable.

And now, having understood how to connect a double pass switch, you can move on to complex circuits.

Installation and connection diagram of a three-key pass-through switch

The connection diagram of the three-way switch is basically no different from the previous options. The only difference is in the number of wires. The fact is that on such a device there are no longer 6, but 9 terminals. By analogy with the previous option, 3 more wires are added. At the same time, 2 out of 3 are marked with multi-colored electrical tape.

How to connect pass-through switches: connection diagrams and video instructions

In order to more clearly understand how to connect a pass-through switch, we offer the dear reader to watch the video instruction, which will more clearly and fully explain the installation algorithm.

But there are times when it is necessary to install a pass-through switch in three or even four rooms. With this option, it will no longer be possible to use only checkpoints - there can be only two of them in the circuit. This means that additional equipment is required. It is called a cross switch. Connecting it is also not too difficult. Especially if the home master has already figured out in detail with the previous installation. But you cannot but talk about cross-breakers.

Wiring diagram of a pass-through switch from 2 places: summarizing information

We have disassembled the connection diagrams for 2-point pass-through switches above in stages, but still some clarifications should be made. In general, in electrical engineering, when it comes to designing, planning the wiring in a building, there is no such thing as "installing a pass-through switch". A single number is not acceptable here. In any such scheme, connecting pass-through switches from two places is an axiom. With an increase in the number of control points, cross control points are included in the scheme. But still there will always be only two penetrators, no more, no less.

Shown: 2,3,4 and 5 are cross switches

But if the scheme for connecting switches from two places is clear, then what about if it is necessary to control from several points? We'll figure out.

Connection diagram of a pass-through switch with 3 places: installation nuances

To begin with, to be extremely precise, there are no 3-place walk-through switches wiring diagrams. Indeed, in this case, additional contacts are required for switching in such devices. But this expression has already become firmly established in the everyday life of electricians.Everyone perfectly understands what it is about.

Loop switches can even be like this

The fact is that the installation of a 3-point pass-through switches connection diagram involves the inclusion of an additional link - a cross switch. The connection is quite simple. According to the circuit located on the back cover of the switch, it is included in the gap between the bushings. You can learn more about this in the following video.

How is the connection diagram of the pass-through switch from 4 places carried out

The wiring diagram of the 4-point pass-through switch does not differ at all from the previous one. Here only one more cross is added. Thus, adding cross switches can increase the number of control points.

Overview of manufacturers offering similar equipment

Nowadays, the range of such equipment on the shelves of electrical stores is quite wide. This means that you can choose and buy a pass-through switch at a different cost, which depends on the manufacturer. Let's try to list the most popular brands, and then compare them by price:

These are the most popular brands on Russian counters, and therefore it is worth considering the prices of walk-through switches set by them.

Typically jumpers are used with similar designs

Legrand is the most popular brand

Pass-through switches "legrand" have a fairly wide range of models that differ both in color and type. Let's try to cite just a few of them.

Photo	Model	Colour	Number of keys	Cost, rub.
	Legrand Mosaic 2M	White	1	1200
	Legrand Valena	Ivory	1	600
	Legrand celiane	Beige	1	250
	Legrand Valena	White	2	450
	Legrand Quteo	Ivory	1	250
	Legrand Etika	White	2	400

It can be understood that the purchase of Legrand pass-through switches will not damage the budget. Although there are more expensive models. In any case, the quality of this brand raises no objections, which means they will serve for a long time.

But touch switches are something new on the market

"ABB" - what is the cost of models of this brand

A fairly well-known brand that is famous for its protective automatics. It is appreciated mainly for its quality and reliability. In addition, the pricing policy of this manufacturer is quite democratic. This is not to say that its model range is wide enough, and the brand does not amaze with the colors of the cases.

Photo	Model	Colour	Number of keys	Cost, rub.
	ABB BJB Basic 55	White	1	600
	ABB BJB Basic 55	Beige	1	200
	ABB BJB Basic 55	Beige	2	400
	ABB BJB Basic 55 Chateau	The black	3	2500
	ABB BJB Basic 55 Chateau	The black	1	700

Of course, we can say that some of the models are quite expensive, but quality and safety are more expensive.

Model range "Schneider Electric"

In terms of the quality of products, it is not inferior to the previous ones, but less well known. This means that the cost of production is somewhat lower.

Photo	Model	Colour	Number of keys	Cost, rub.
	Schneider Electric SE GSL000161	White	1	70
	Schneider Electric SE GSL000163	White backlit	1	90
	Schneider Electric SE GSL000165	White	2	120

	Schneider Electric SE GSL000261	Beige	1	70
	Schneider Electric SE GSL000565	Oak	2	220

This is approximately the cost for the products of this brand.

Here, a similar one is combined with an outlet. Looks gorgeous in black

Viko brand and its cost for products

The brand's lineup is rather scarce. Basically, the differences are only in the colors of the products. The average cost of their pass-through and cross-over switches varies from 150 to 350 rubles. The form is classic, no frills are observed. Quite acceptable quality at an affordable price.

Models "Lezard": what are their differences

It also does not differ from the previous brand in terms of the size of the model range, but the cost of products is much lower.

Photo	Model	Colour	Number of keys	Cost, rub.
	The world	Metallic gold	1	110
	The world	White	1	70
	The world	Metallic gold	2	150
	Nata	White	1	70
	Nata	Cherry	1	140

Finally

Summing up, we can say with confidence that the appearance of pass-through and cross-over switches on Russian counters greatly facilitated the work of both electricians and home craftsmen. After all, their field of application is not only long corridors or staircases. Nowadays, quite a few people install such switches in small rooms. For example, a home craftsman wants to have additional lighting control near a sofa or bed. Surely in the future they will be improved, new functions will appear.

Retro style never goes out of style

However, even now they have undeniable advantages. The main thing is energy savings, even in comparison with motion or sound sensors. After all, there is no delay after a person leaves.

We hope that the information presented today was useful to the dear reader. If you still have questions on the topic, our team is always ready to answer them in the discussions for this article. And finally, we offer one more video on the topic:
