It is commonly used in electrical wiring to control the power supply to two different electrical devices or circuits. The wiring for a 2 pole switch involves connecting the switch to a power source and then connecting each of the two circuits to the switch. This allows the user to control the power supply to each circuit independently.

The term POLE refers to the number of circuits that can be controlled by the switch. In the example below, the single-pole switch is capable of interrupting the current in a single circuit. A double-pole switch, on the other hand, is capable of simul-taneously interrupting the current in two separate circuits.
