This one-of-a-kind 4-stud motorized battery switch stands out by combining remote switching with advanced Voltage Sensing Relay (VSR) functionality. Designed for demanding power systems, it’s ideal for applications with an engine and house battery—such as large vessels or RVs—where smart, automatic energy management is critical.

The Motorized Battery Switch with VSR offers two modes of operation: Auto and Manual. In Auto ON, the switch actively monitors both the start and house batteries, automatically combining them to ensure optimal charging without overloading either bank.

Built for high current loads, the unit is rated for 300 amps and features 3/8″-16 tin-plated copper studs for maximum conductivity and corrosion resistance. Mounting hole spacing is 2.13″, and it’s available with your choice of black, red, or yellow knob to suit your system’s color standards.

For installers seeking intelligent control over complex dual-bank systems, this motorized switch with integrated VSR is a robust, all-in-one solution.
