We stock a variety of high-quality battery disconnect switches (also referred to as Master ON/OFF disconnect switches) for your projects. Many sanctioning bodies require the use of a Master ON/OFF disconnect switch for any vehicle competing with a rear-located battery. This allows their safety team to quickly disconnect power to all vehicle accessories as well as turn off a running engine in the event of an accident.

Which Disconnect do you need? Easy, we’ve laid that out in plain English in our Battery Disconnects 101 blog.
