Description

The M-750 Series 36V 310A Dual-Battery Selector &

Master Disconnect Switch is ideal for boats, emergency

vehicles, buses, heavy trucks, and RVs that use one

battery for starting the engine and another battery to

power auxiliary loads.

This automotive and marine battery selector switch has

single-pole, triple-throw (SP3T) circuitry, which gives you

four options: batteries OFF, battery 1 ON, battery 2 ON, or

both batteries ON simultaneously.

The battery cutoff position ensures reliable battery

disconnection to protect against electrical fire, tampering

or theft, and battery drain, while the selector switch

positions allow for maximum starting power and backup

starting power during emergencies.
