A rotary switch is an electrical component that allows multiple circuits to be controlled or selected by rotating a knob or lever. It consists of a rotating contact arm that connects with various fixed contacts positioned around a central hub. By turning the knob or lever, the user can change the electrical connection and thus control different devices or functions. Rotary switches can vary in complexity and configuration.
