Light switch principle

The principle of the light switch is the two single-pole, double-throw switch two contacts are connected, that is, switch 1 contact 1 and switch 2 contact 1 connected to switch 1 contact 2 and switch 2 contact 2 connected to switch 1 contact 2, and then the two switches of the knife to do the whole switch at both ends connected to the two ends of the electric lamp.

This way, when the knives of switches 1 and 2 are simultaneously connected to their respective contacts 1 or to contact 2 at the same time, the circuit is connected, then the light is on. If the knife of the two switches a hit to contact 1 and the other hit to contact 2, the circuit is not available, the light is off. So both switches can control the light.
