Battery Disconnect Switch 12/24V Copper Master Cut Off for Ford BMW
Stop your battery from drifting to empty while the vehicle sits parked. This copper master switch breaks the main circuit with one clean turn. You take full control over every accessory draw and protect sensitive electronics from unexpected power loss.
Pure copper contacts conduct electricity efficiently and resist corrosion over time. The built-in 12 and 24 volt rating lets you run the same unit on pickup trucks, RVs, classic muscle cars, or modern Fords and BMWs. Slide it onto your dash or console so you can isolate the system before leaving town.
