Battery Disconnect Switch 12V-48V Top Post

A battery disconnect switch that connects directly to the negative terminal of top post batteries (17 mm cone taper), isolating your electrical system instantly.

Fits DC 12V to 48V systems with no modifications needed. Rated for 275 A continuous at 12V, with intermittent and momentary ratings up to 1250 A. The ABS plastic housing is built to withstand heavy-duty use in harsh marine and mobile environments.

Install the switch between your battery negative and the vehicle’s ground circuit. It eliminates parasitic power drain when your car, RV, or boat sits unused for extended periods—a critical safety feature for marine vessels and seasonal vehicles. The switch operates in two positions (ON/OFF) and can stand alone or lock together with another switch for dual-battery setups.

Works across cars, recreational vehicles, boats, and caravans. Check your installation space before purchase to ensure the switch body clears surrounding components.
