Straight-through or crossover switch, consider the connection diagrams

We all know that an ordinary switch to turn on and off light only from one place. And what if you need to switch immediately from different angles, such a conventional circuit not realizuesh. There is required a so-called pass switch. In this article I'll tell you how to connect them properly.

Application area

Before proceeding to consider the schemes of connection through-breakers, let's find out where they can be used.

Let's look at a concrete example: suppose you have stairs, as the judges have to cover during the ascent. Of course, you can put the switch to the time switch and after you turned it on it will turn off after a set period. And what if the next time you will climb with a heavy load. You agree that to be in the dark in the middle of the stairs not the best option. And if you put a very large time delay, the light will be to no avail to burn and spend your money. Exit - installation walk-through switching devices.

Or here's another example: going into the bedroom, you turned on the light, and lay down to rest. In order that the light would not hurt you, you will again get up and put out the light, and to get the sofa in the dark. Agree, it would be much easier to get comfortable, just klatsnut the switch placed, for example, near a floor lamp, and so disable main light.

So now for the direct connection diagrams

Wiring harness with the management of the two places

In fact, in the present process has very little complicated and the only difference from the usual connection of the switch is that in our case, the three cores and a passing switch thereof at three contacts, rather than two as in the ordinary switch.

So now we go over the circuit: the power comes to us two-core conductor, with whom we zero directly connect to zero of our lighting products, but we will miss phase through our switches. The path will be as follows: the phase is connected to the common input terminal chandeliers. With the first transfer switch output terminals, with the same twisting contacts the second flow switch. A second switch has an input terminal is connected with the end phase of our bulbs. Ready to lay in the box will look like this:

As you can see, this process is simple. The main condition is to have in your box could fit all of the twists and switches were just three wires.

Connecting the three switching devices for controlling one lamp

Sometimes there is a situation that must be not two, but three control points, for example in the hallway out several rooms and you need to lighting could include near each door, or to light once the whole flight of stairs with the ability to enable or disable each site.

Judges the system might perform, but in a variant in addition to the walk-through switch, you will need even the so-called cross-over.

The principle of this scheme is such that the first and last point of the circuit breakers are just transient, but established cross between them.

It is important in this case the number of cores in the box begins to grow, and in order not to get lost in them, better, label each wire. Connection diagram looks like this:

The algorithm works as follows: zero attached directly to the light source and the first phase comes to the input terminal flow switch, then goes to the output terminals the input terminals of the cross-switch, with it comes and goes to the output contacts the flow switch, and only with him, through the output terminal on lamp. As you can see, there is also no difficulties. The main thing to remember that in order to connect through-switches you need three wires, and only for the connection of cross-switch requires four wires.

That's all I wanted to tell you about the connected-through and cross-switches. Thanks for attention.
