How Does a Switch Work in a Circuit?
The three main functions of a switch are to open or close an electrical circuit, control the speed of a motorised device, and limit the amount of current flowing through a circuit. Switches come in different sizes and ratings to handle different loads, so make sure you choose the right switch for your circuit.

Electric switch
An electric switch is an electrical component that breaks or closes an electric circuit. Opening the switch (breaking the circuit) means turning off the electrical device and closing the switch (completing the circuit) allows an electrical current to flow so that the device is on. Examples of electric switches.
