Lamp dimmer switch – It’s a job I’m doing myself, although I have to admit that I had to retrieve the notes of the race to remember how the commutated and crossed switches work. I guess we all know how a conventional switch works, but just in case we’re going to explain it again. The installations of our homes use a single-phase alternating current system, which consists of three wires: the phase, which carries the current, the neutral, which closes the circuit, and the earth, which prevents the passage of current to the user In case of insulation fault.
When we are placing the switches, the only cable that concerns us is the phase. Because the neutral and the earth must go directly to the point of light. In the case of a single switch, we simply pass the phase cable through it before taking it to the light point, and so we can control its on and off simply by opening or closing the switch key, which will or will not let the current flow .Today, although we sometimes use them as simple, the vast majority of switches that are marketed are switched. Its function is to allow control of a light spot from two different lamp dimmer switch, very useful for example in corridors, where one switch is placed at the beginning and another at the end.

In this case the phase must pass through the two switches before going to the lamp in question. With the particularity that both switches must be connect by a pair of cables, which is what. Allows when opening or closing any of the two keys, the light goes from on to off or vice versa. The best way to understand this is with diagrams. In the first we see how the current cannot reach the lamp. Because the second switch prevents it. However, if we drive the first, the current can pass, even if we have not touched the second. If we then drive the second, it does not reach its destination again.
We already know how to control a light with two lamp dimmer switch, but what if we need three? For this we have the crossed switches, which combined with the switches. Allow us to control a light with so many switches we want. This is a common case of the double bedroom. Where we want to be able to turn on the light from the door. And then turn it off from both sides of the bed (or the other way round).
