A switch is a component or device that switches function of a circuit, switching it's position from on and off.
The mechanism of a switch in an electric circuit is that the position of the contact point changes when a button is pressed or a lever is pulled down, and the circuit is switched or interrupted when the contact points in the electric circuit are connected or separated.
In a two-story house, a light switch is installed next to the staircase connecting the first and second floors, and the light can be switched on and off at either end. Here is a brief explanation of how this works. The assumption is that the switches on the first and second floors both have contacts that connect to Circuit A or Circuit B.
Thus, switches can switch the mode of operation of a facility or turn lights on and off by switching which circuit carries the current or interrupts the current.
There are various types of switches, some of which are listed below according to the type of switching method.
The circuit is connected only when it is pushed in, and when the finger is released, the spring returns to shut off the circuit.
