Rotary Switches and Mechanical Encoders
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.
Mechanical encoders combine the feel of our rotary switches with a digital output. They provide an economical way of obtaining Octal, Binary Coded Decimal, Hexadecimal and Gray code output from a rotary switch. Standard products include offerings with concentric shafts, isolated positions and adjustable stops.
