how does a light switch work

Summary

A light switch works by interrupting the flow of electricity when it is turned off, and connecting the two ends of the wire when it is turned on. This is done by using a piece of metal, usually brass, to connect the two ends of the wire. 1 2 Different types of wall switches are available, including mechanical, snap, and micro switches, and they come in a variety of designs, sizes, and materials. 3 The hot wire from the power source is connected to one of the terminals, and the black wire is spliced to a black wire in a cable that runs to the switch. 4 Flipping the switch interrupts the flow of electricity, and the switch does its job. 2
