Cole Hersee Push Pull Switch SPST On-On-Off 3 Screw

The Cole Hersee Push Pull Switch SPST On-On-Off 3 Screw is a dual-position electrical control switch designed for 12V and 24V systems in automotive, marine, and industrial applications. This rugged panel-mount switch allows operators to select between two independent circuits or disable power entirely, making it ideal for managing auxiliary equipment, lighting systems, and accessory controls on vehicles and equipment. The push-pull actuator design provides tactile, reliable engagement without requiring complex wiring infrastructure.

Built to exacting Cole Hersee standards, this switch handles 10 amps at 12VDC and operates across the 6–36VDC range, ensuring compatibility with most low-voltage DC systems. The SPST (Single Pole Single Throw) circuit topology with On-On-Off functionality allows independent control of two loads or a single load with an off position, depending on wiring configuration. Chrome brass actuator knob with 10-32 thread provides secure, corrosion-resistant engagement and easy panel integration, while the three-screw terminal block ensures solid electrical connections without solder joints or crimping.

This switch is ideal for auxiliary power management on trucks, trailers, RVs, and marine vessels where space is limited and operator control must be immediate and intuitive. Users benefit from the fail-safe Off position—power defaults to disconnected when the actuator is released—reducing the risk of accidental equipment operation. Installation requires only a standard panel cutout and basic DC wiring; the compact 3 x 2 x 7-inch footprint fits snugly into most dashboard or console layouts. Rated for continuous industrial and automotive duty, this Cole Hersee switch delivers decades of reliable switching performance in harsh environments.
