Masterswitch ON-OFF

Eliminate any power drawn from the battery when the vehicle/boat is not in use.

Battery Master Switches shut down a vehicle's electrical system by cutting off current from the battery. They are designed to help prevent tampering, theft, battery drain and electrical fires. Preserve battery life by cutting off the power supply to a battery with the simple turn of a switch or key. These convenient switches can be used for both marine and automotive applications.
