Wiring a light switch – You all know how a conventional switch works, but just in case we will explain again. The facilities of our homes use a system of single phase alternating current, which consists of three wires: phase, which carries the current, neutral, which closes the circuit and the ground, which prevents the passage of current user in case of insulation fault.
When you are placing the wiring a light switch, the only cable in question is the phase, as the neutral and ground must go directly to point light. In the case of a simple switch, we simply pass the phase wire by him before taking him to the point of light, and thus can control the on and off simply by opening or closing the switch key that will leave or current will not let go .

Wiring a light switch sometimes you use them as singles, the vast majority of switches that are marketed are switched. Its function is to allow control a point of light from two different switches, very useful for example in corridors, where a switch is placed at the beginning and the end. In this case the phase must pass through the two switches before heading to the lamp in question, with the particularity that both switches must be connected by a cable pair, which is what allows you to open or close any of the two keys, light pass on to off.
