Top Rotary Switch Manufacturers and Suppliers in America

Introduction to Rotary Switches

Rotary switches enable users to select different operational modes or circuits, commonly found in applications like band selectors on radios, speed controls on fans, and industrial equipment controls. Unlike simple toggle or pushbutton switches, rotary switches rotate a shaft to one of many fixed positions, each connecting different circuits or configurations.

Benefits of Rotary Switches:

- Multiple positions control multiple circuits.

- Durable and suitable for harsh industrial applications.

- Versatility in electrical ratings and configurations.

- Reliable mechanical operation with precise detents.

Rotary switches can be found in various designs such as wafer, turret, cam, and detent types, adapting to different mechanical and electrical requirements. Their robust construction and ability to handle relatively high current loads make them indispensable in many high-demand switching scenarios.
