A light switch is a switch, usually in the shape of a rectangle or compressed prism, which operates an electrical switch, two wires that are pressed together to form a current, to turn on and off a light.

In modern homes most lights are operated using switches set in walls to operate ceiling lamps, while in torches the switch is far nearer the bulb. Home light switches, being in reality a metal box with a switch, commonly have switch plate covers; these are commonly made of plastic or tile, and are purchased to allow the switch to more properly blend in with the style of a room.
