Perko Single Battery Disconnect Switch w/Mounting Ring & Legs - Bulkhead Mount

The Perko Single Battery Disconnect Switch w/Mounting Ring & Legs – Bulkhead Mount is a critical safety component designed for marine and electrical system applications where reliable battery isolation is essential. This heavy-duty disconnect switch allows operators to completely shut off battery power when vessels or equipment are not in use, simultaneously serving as an emergency main disconnect in crisis situations. Originally engineered for marine environments, this switch is valued by professionals who require positive control over electrical circuits—including law enforcement marine units, military support vessels, and first responders who depend on fail-safe power management during extended deployments.

Built by Perko, a trusted manufacturer with deep roots in marine and industrial applications, the Single Battery Disconnect Switch features a bulkhead-mount design with integrated mounting ring and support legs for stable, vibration-resistant installation. The compact footprint—measuring 4 x 3 x 8 inches and weighing just 0.6 lbs—allows flexible mounting in tight spaces without compromising mechanical integrity. The lever-actuated disconnect mechanism provides instantaneous circuit breaking, eliminating parasitic drain and preventing battery depletion during storage or standby periods. This design also protects sensitive electronics and reduces fire risk by isolating the power source completely rather than relying on conventional breakers or fuses alone.

Tactical and maritime professionals benefit from this switch's ability to provide emergency power isolation in high-stress scenarios—critical for vessels operating in remote or hostile environments where electrical fires or system shorts could compromise mission capability or crew safety. Installation requires bulkhead mounting with the supplied ring and legs, making integration straightforward for OEM applications or retrofit duty. The switch is compatible with single-battery systems across 12V and 24V marine platforms, as well as mobile command vehicles and generator-equipped support equipment. For anyone managing independent power systems in vehicles, boats, or portable tactical setups, this disconnect switch represents proven reliability backed by decades of marine industry standards.
