Rotary Switches

Grayhill is the leading manufacturer of single and multi-deck rotary switches with extremely rugged construction and virtually limitless configurations. Many of our rotary switches are MIL qualified to exacting electrical, mechanical and environmental standards. We offer many options including isolated positions, spring returns, adjustable stops, concentric shaft switches and configurable keylock switches. Standard rotaries can be configured with solder lug termination, PC termination, various angles of throw and multiple poles. Contact a Grayhill representative early in your design process to discuss your application. In many cases, we can meet your requirements with a standard option or a simple modification.
