Cole Hersee Heavy Duty Toggle Switch SPDT (On)-Off-(On) 3 Screw

The Cole Hersee Heavy Duty Toggle Switch SPDT (On)-Off-(On) 3 Screw is a robust electrical control component engineered for vehicles, equipment installations, and systems where reliable momentary or maintained switching is required. This SPDT (Single Pole Double Throw) configuration delivers industry-standard switching functionality with dual-throw capability—allowing power to be routed to one of two circuits or held in a neutral off position. Built on proven Cole Hersee specifications, this switch handles 25 amps at 12V DC, 15 amps at 24V DC, and 10 amps at 36V DC, making it suitable for a wide range of automotive, marine, and industrial applications.

The switch features a nickel-plated brass mounting stem with 15/32" -32 thread and 11.9mm length, designed to fit panels up to 9/32" thick. Silver contacts ensure clean electrical transitions and extended lifespan under repeated cycling. The phenolic housing with plated steel cap resists corrosion and mechanical wear, while nickel-plated brass hardware provides durability in challenging environments. Blade terminals accept standard .250 quick-disconnect fittings, and screw terminals use 6-32 fasteners for secure permanent connections. The 3-screw design provides additional terminal security compared to simpler alternatives.

This toggle switch serves operators and technicians installing custom electrical systems in tactical vehicles, emergency response equipment, off-road rigs, and marine platforms. The dual-throw configuration is essential for applications requiring independent circuit control—such as switching between auxiliary lighting modes, pump operations, or redundant system activation. Heavy-duty rated contacts and corrosion-resistant materials perform reliably in salt-air, high-vibration, and temperature-fluctuating environments typical of field operations and remote deployments. The compact 3 x 1 x 4-inch profile fits standard switch panel cutouts without requiring custom fabrication.
