Rotary Switches

Rotary military switches are designed to withstand impact, vibration, temperature variation, and natural events.

Fully enclosed switching mechanisms protect the unit from dirt, sand, and moisture. Quick make-and-break action works for dc as well as ac switching. Stationary low-resistance, doublewiping contacts can be nonshorting, shorting, or "sweep" style. Rotor blades can be simple (single-throw switching in one circuit and double-throw in another), right-angle (for double-throw switching and an intermediate off position), or multifingered (for double-throw, triple-throw, or four-throw switching.
