Cole Hersee 3 Position Sealed Ignition Switch

The Cole Hersee 3 Position Sealed Ignition Switch is a heavy-duty rotary control designed for vehicle electrical systems, marine applications, and custom automotive builds where reliability under harsh conditions is essential. This switch is ideal for those restoring classic trucks, building custom race cars, or upgrading marine engine compartments, providing dependable on-off-start functionality that professionals trust.

Engineered from rugged, high-grade plastic composite, this switch resists mechanical shock, vibration, and corrosion—critical advantages when mounted in engine bays, under dashboards, or exposed to moisture and salt spray. The sealed construction prevents water ingress and contaminant buildup, extending service life in off-road, marine, or harsh industrial environments where conventional switches fail prematurely.

Its compact form factor (4 x 3 x 7 inches) allows flexible mounting options, and the integral Deutsch connector integration ensures professional-grade reliability for both OEM replacement and aftermarket custom installations. This switch is particularly beneficial for hot-rodders, restoration specialists, and technicians building custom wiring harnesses where factory ignition switches lack the durability or functionality needed.
