Subminiature Basic Switches

SM Series

Up to 5 A ac & dc (UL, CSA, CE, ENEC). Variety of actuators, terminations & contacts. 9,5 mm centers side mount. MIL-PRF-8805 listings

Distributor Inventory

The MICRO SWITCH SM Series’ small size and light weight are combined with ample electrical capacity, precision operation, and extended life. Featuring high precision and repeatability, the SM Series offers gold contacts for low-energy switching and gold bifurcated contacts for maximum reliability. Bifurcated contacts provide parallel redundancy within the SM switch. The SM switch is available for power-duty switching up to 11 A (Vac) or 1/4 HP (Vac).
