The switch simply opens off or closes on the connection between the two terminals on the switch. Behind the plate are the inner workings of the main light switch.
Light Switch
Inside a light switch. You can see in the figure that the current runs through the switch. In a single pole switches there is a spring loaded metal gate inside the switch that opens and closes the electrical circuit leading to the light fixture. Used for normal lighting circuits with a single switch controlling one or more lights. The switch and the plate. When the switch is on current flows along the black wire through the switch to the light and then returns to ground through the white wire to complete the circuit. The first and foremost parts of the light switch are the parts that everyone deals with on a day to day basis.
And mr light switch that is now dead. In this video we look at how light switches work in this video we look at a simple one gang one way switch as well as a one gang two way switch as well as an intermediate switch. A one way switch has two terminals. The plate serves as the aesthetic barrier that covers the hole in the wall. These have three terminals usually marked c l1 l2. Remember to recycle kids.
When you toggle the level to the on position the gate snaps closed completes the circuit and allows power to flow through the switch and onward to the light fixture. In one position the terminals are connected together in the other the terminals are not connected. The switch is the actual object that you switch up and down.
