Rotary switch is a switch operated by rotation. These are often chosen when more than 2 positions are needed, such as a three-speed fan or a CB radio with multiple frequencies of reception or “channels”.
A Potentiometer consists of a spindle or “rotor” that has a contact arm or “spoke” which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the “spoke” through which any one of a number of different electrical circuits can be connected to the rotor. The switch is layered to allow the use of multiple poles; each layer is equivalent to one pole. Usually such a switch has a detent mechanism “clicks” from one active position to another rather than stalls in an intermediate position. So rotary switch provides greater pole and throw capabilities than simpler switches do.
Some rotary switches are user configurable in relation to the number of positions. A special toothed washer that sits below the holding nut can be positioned so that the tooth is inserted into one of a number of slots in a way that limits the number of positions available for selection. For example, if only four positions are required on a twelve-position switch, the washer can be positioned so that only four switching positions can be selected when in use.
