Cole Hersee Heavy Duty Push Button Switch SPST Off-On 2 Screw - 35A

The Cole Hersee Heavy Duty Push Button Switch SPST Off-On 2 Screw - 35A (Model M-490-BP) is a workhorse electrical component designed for mission-critical applications in tactical, military, and law enforcement vehicles and equipment. This push-to-momentary switch delivers reliable circuit control in demanding environments where dependability directly impacts operational success. Whether integrating auxiliary lighting systems, accessory power distribution, or emergency communication circuits, this switch has proven its durability across field operations and high-stress installations.

Built with heavy-duty construction, the Cole Hersee switch handles 35 amps at 12V DC—the standard vehicle electrical platform for most tactical platforms—with rated capacity dropping to 20A at 24V and 10A at 36V as voltage increases. The SPST (Single Pole, Single Throw) configuration provides simple on-demand circuit closure with a normally-off position, preventing accidental activation during transport or storage. Two brass screw terminals ensure corrosion-resistant connections that withstand vibration, temperature cycling, and moisture exposure inherent to field operations. The 5/8"-32 threaded brass mounting stem (1 3/8" long) accommodates standard panel cutouts and provides secure mechanical retention without additional hardware complexity.

Tactical vehicle integrators, armored platform technicians, and equipment manufacturers specify Cole Hersee switches for emergency systems, strobe light circuits, winch controls, and supplemental power distribution where momentary actuation and high reliability are non-negotiable. The compact footprint (3" × 2" × 7") fits tight panel-mount applications common in military electronics bays and law enforcement vehicle dashboards. Installation requires only two wire terminals and a standard dash or console cutout; no relay logic or complex wiring schemes needed. This switch delivers the simplicity and ruggedness that field-proven systems demand.
