Battery Disconnect Switch 2-Pack, 12V/24V Terminal Kill Switch Cut-Off

Stop Battery Drain When the Vehicle Sits

Project car, weekend toy, RV or boat sitting for weeks? Small parasitic draws from clocks, alarms and modules can flatten a battery while it sits. This terminal-mount disconnect switch cuts power with a quarter turn of the knob, with no tools needed, so the battery is ready when you are.

It's also a simple anti-theft measure: with the switch off, the vehicle won't crank.
