Selector switch

 Selector switch

A selector switch can control on or off of different currents circuit by rotating the handle. Common used for control consisting of a mechanical or electrical or electronic device for making or breaking or changing the connections in a circuit. Selector switches have two positions and three positions, illuminated and non-illuminated selector switches.

Selector switches are available in a variety of styles including illuminated, non-illuminated, and non-illuminated key operated. Styles offered range from maintained or spring return, incandescent or LED, and 3-50 amps. Work with a selector switch specialist to determine the best product for your application.

This product overview focuses mainly on the construction and functionality of Non-Illuminated Selector Switches. 

What is a Selector Switch?

Selector Switch works on a general principle; they contain a simple selector switch on the front of the panel, and a broad range of potential contact combinations (via the contact blocks), on the inside of the enclosure. The major difference between the selector switch and the pushbutton is that, while a pushbutton has a plate that pushes down both contact plungers at the same time, a selector switch has a rotating cam with ridges and flats, allowing to actuate the plungers independently.

Selector switches are available in 2, 3, or 4-position versions, and are often used when more than one control option is needed. In general, the center position of the selector switch is the starting cam position. Left position presses the left plunger in the selector switch. Turning the selector switch to the right presses down the right plunger.
