What It Is / How It Works

This car battery cut-off switch is a battery switch that goes in the battery circuit to interrupt the power supply when the vehicle is not in use. Battery cut-off switches are a common accessory for cars, trucks, RVs and ships.

Who It's For / Use Cases

Battery cut-off switches suit owners of cars, trucks, RVs and ships who leave a vehicle parked for long periods and want to stop standby electronics from draining the battery. They also suit anyone who wants a manual way to isolate the battery during maintenance.

How to Use / Care

1. Install the switch in the negative power supply so it can cut off the battery circuit.
2. Turn the manual knob to switch the circuit on or off; no tools are needed.
3. Switch the circuit off during long-term storage to cut off the standby draw of clocks and alarms.

How to Choose

Check that your battery system is 12V or 24V, since this switch is made for both. Match the switch to the vehicle type you own, whether a car, truck, RV or ship. If you store a vehicle for long periods, a switch that cuts off standby draw is the main feature to look for.
