Cole Hersee Sealed Toggle Switch SPDT On-On 3 Wire

The Cole Hersee Sealed Toggle Switch SPDT On-On 3 Wire is an industrial-grade electrical component designed for demanding automotive and off-road applications where reliability is crucial. This switch is perfect for wiring custom auxiliary lighting circuits, managing dual-battery systems, or integrating switchable fuel pump controls in high-performance engine bays.

Featuring a sealed design, this toggle switch protects internal contacts from corrosion, salt spray, and moisture ingress, making it suitable for harsh environments. Its SPDT (Single Pole Double Throw) configuration allows users to select between two independent electrical paths, ideal for applications that require instant switching between two active states.

Mechanics and fabricators often choose Cole Hersee switches for custom truck builds, marine electronics, and emergency vehicle upfits, where OEM switches may lack the necessary flexibility. The 3-wire terminal design integrates seamlessly into existing harnesses, supporting both DC and low-current AC applications typical in vehicle wiring.
