Product Overview
If a car, truck, boat, RV, or stored project keeps draining its battery between uses, a manual disconnect gives you a simple way to break the circuit without removing a cable every time. It is also useful when you want a clear power shutoff before electrical work.
This side-post switch mounts at the negative battery connection and opens or closes with a visible knife lever. It is a practical replacement for a corroded disconnect or an upgrade for vehicles that sit for long periods. Confirm terminal style, clearance, cable reach, and current demand before ordering.
