Description

Take control of your vessel’s electrical system with this Heavy-Duty Dual Battery Selector Switch, designed for reliable battery isolation and power distribution in boats, yachts, vehicles and other 12V or low-voltage electrical systems.

Featuring a versatile 4-position rotary selector – 1, 1+2, 2 and OFF – the switch allows you to select between two battery banks, combine both batteries when required, or completely isolate battery power. This makes it an ideal solution for dual battery marine systems where dependable power management is essential.

Built with a durable high-strength plastic housing, easy-to-operate red rotary knob and non-corrosive marine-grade metal components, the battery switch is designed for long-lasting performance in demanding environments.

With a rating of 350A continuous duty and 600A intermittent at 12V DC, plus a maximum operating voltage of 32V DC, it provides the high-current capability required for a wide range of marine and automotive battery installations.
