A rotary switch is an electromechanical device that allows users to control a circuit by turning a knob or shaft through a series of positions. Each position corresponds to a different circuit path, making rotary switches ideal for applications that require multiple selection options from a single control point. The internal contacts rotate with the knob, connecting different poles (input terminals) to one or more throws (output terminals), depending on the switch's configuration. Options like single-pole, two-pole, or even multi-deck designs offer flexibility in complex systems.

Rotary switches are commonly found in electronic equipment, control panels, instrumentation, and industrial machinery, as well as in consumer devices like car dashboards where a rotary switch might control lighting or air flow. A two-pole rotary switch, for example, allows two separate circuits to be switched simultaneously, ideal for audio, test, or telecom applications. Compared to a rotary encoder or a selector switch, rotary switches typically offer a more tactile, mechanical detent-based selection method. Unlike a DIP switch, which is set using small levers or slides, a rotary switch is adjusted by turning, which can be more user-friendly in low-visibility or gloved-use situations.
