The M-750 Series 36V 310A Dual-Battery Selector & Master Disconnect Switch is designed for boats, emergency vehicles, buses, heavy trucks, and RVs that use separate batteries for engine starting and auxiliary loads. Featuring SP3T circuitry, it offers four positions: OFF, battery 1 ON, battery 2 ON, or both ON simultaneously. The cutoff position ensures battery disconnection to prevent electrical fire, tampering, theft, and battery drain, while the selector positions maximize starting and backup power in emergencies.
