What is a Rotary Switch?

A rotary switch is a switch operated by allowing rotation to control different circuit functions. To do this a Rotary switch consists of a spindle or "rotor" that has a contact arm or "spoke" that projects from its surface like a cam. It also has an array of terminals, arranged in a circle around the rotor, where each terminal can serve as a contact for the "spoke". In this way any one of a number of different electrical circuits can be connected to the rotor.

The benefit of a rotary switch is that they are layered to allow use of multiple poles, where each layer is equivalent to one pole. In most case, rotary switches have a detent mechanism so it "clicks" from one active position to another rather than stalls in an intermediate position. Because of these attributes, rotary switches can provide greater pole and throw capabilities than a simple switches.

Types of Rotary Switches

There are many different kinds of Rotary Switches and at Future Electronics we offer you a wide variety of Rotary Switch from such suppliers as C &K, Grayhill. E-Switch, EECO and NKK Switches:
