Description
If you want to keep your boat, RV, or project vehicle safe from battery drain and unauthorised use, a battery selector switch with a key is an excellent choice. This device acts as a "master kill switch," stopping any phantom loads, like clocks or stereos, from draining power while your vehicle is not in use.
Unlike standard rotary switches that anyone can operate, a keyed version provides an extra layer of security.
Anti-Theft: Without the key, the ignition system and starter can't be activated.
Safety: It prevents the accidental activation of winches, thrusters, or heavy machinery during maintenance.
Battery Preservation: The switch completely isolates the battery bank, stopping "parasitic draw" during storage.
