Product Description

Honeywell MICRO SWITCH SX Series is a premium subminiature snap-action switch from the family of S series subminiature basic switches. Although small in size, the SX Series is rated for controlling electrical loads ranging from logic-level/ computer-based circuits to limited power-duty switching (up to 7 A/ 250 Vac). The SX premium subminiature switch package offers gold contacts for low energy switching and bifurcated gold contacts for maximum reliability. Bifurcated contacts provide parallel redundancy within the SX switch.

A wide variety of stainless steel levers are available and when combined with the subminiature package size, can adapt the SX Series to a wide range of applications. To enhance the versatility of SX switches, the family is certified to UL, CE, CSA, ENEC, MIL-PRF-8805, FAA-PMA and UKCA for worldwide use. The SX Series is the right choice for a cost-effective premium subminiature switch package.
