Cole Hersee Metal Body Battery Disconnect Switch SPST - 6-12V

The Cole Hersee Metal Body Battery Disconnect Switch SPST - 6-12V (Model 2484-BP) is a professional-grade manual disconnect switch engineered for vehicle electrical system isolation. Mechanics and automotive enthusiasts rely on battery disconnect switches to safely cut power to the entire vehicle during maintenance, storage, or emergency situations. This SPST (Single Pole, Single Throw) configuration provides straightforward on-off control without complex switching logic, making it the go-to solution for shop work, long-term vehicle storage, and custom electrical builds.

Built with a durable metal body, this disconnect switch handles 6V to 12V systems and is rated for manual operation—meaning you control exactly when power is cut. The solid construction resists corrosion and vibration, critical factors in underhood and battery box mounting where temperature swings and moisture exposure are constant threats. Cole Hersee's engineering ensures positive contact and reliable switching with minimal voltage drop, preserving system integrity during both connected and disconnected states. The compact 5 x 2 x 8-inch footprint and 0.95 lb weight allow flexible installation in tight engine bays or custom fabrication scenarios.

This switch suits classic car restoration, race vehicle builds, security applications, and stored vehicle preservation where parasitic battery drain is a concern. Off-road and hot rod enthusiasts appreciate the added safety of instant power shutoff in emergency conditions. Proper installation between the negative battery terminal and the vehicle chassis ground—or between the positive terminal and the starter/main feed—requires secure mounting and appropriate gauge wiring. For 6V to 12V DC systems with moderate current draw, the 2484-BP delivers the reliability and simplicity that professional mechanics demand.
