Very practical for taking power off a battery quickly and easily. Ideal for cars that are only occasionally on the road. Power is switched off by unscrewing the green wheel against draining the battery and can be used as an anti-theft system. This part fits 6V, 12V and 24V batteries universally.
Set the main switch to the negative pole of the car battery, then connect the battery cable to the breaker.
Simply loosen the knob and the circuit will be interrupted.
