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.

Need to brush up on your skills with switches? No problem. Chapter 4 of Automotive Wiring and Electrical Systems covers switches–and how to put them to work–in-depth.
