Rotary switches are switches that move in a circle and can stop in a few positions they are used to connect a functional circuit within a device to a source of electricity. Rotary switches are used to control many different circuits within a single switch. The electrical charge enters the switch and is then directed to whichever circuit is currently selected by the switch. Rotary switches provide a robust mechanical control system.
