Cole Hersee Heavy-Duty Toggle Switch SPST Off-(On) 2 Screw

The Cole Hersee Heavy-Duty Toggle Switch SPST Off-(On) 2 Screw is a rugged, single-pole single-throw electrical control designed for demanding applications where momentary or maintained contact is required. This switch serves professionals and technicians who need reliable activation circuits in vehicles, marine equipment, industrial machinery, and tactical systems where durability and consistent performance are non-negotiable. Built to withstand harsh environments and repeated use, it delivers the dependable switching action that mission-critical applications demand.

The SPST configuration provides straightforward on-off switching with a momentary-on design when the toggle is pressed upward and spring-return to off when released or held downward. Silver contacts ensure excellent conductivity and resistance to oxidation, minimizing contact resistance over thousands of cycles and maintaining clean electrical connections even in corrosive environments. Two screw terminals allow secure, vibration-resistant wire connections suitable for 12V or 24V DC applications across virtually any equipment platform, from emergency vehicles to specialized industrial rigs.

Installation is straightforward for anyone familiar with basic electrical wiring—simply attach your positive and negative leads to the two screw terminals and mount the switch housing through a single-hole cutout in your control panel or dashboard. This versatile switch performs equally well in automotive auxiliary lighting circuits, emergency warning systems, pump controls, and tactical equipment setups. Its universal design and compact footprint make it ideal for retrofit installations where space is limited or where existing switch assemblies need upgrading to military-grade standards.
