Sea-Dog Mini Battery Switch Key w/Removable Knob - 32V & 300A

The Sea-Dog Mini Battery Switch Key with Removable Knob is a compact, marine-grade electrical isolation device engineered for vehicles, vessels, and tactical equipment requiring reliable battery disconnection. Rated at 32V and 300A, this mini battery switch serves law enforcement, military personnel, and field operators who need instantaneous power cutoff in confined spaces or high-vibration environments. The removable knob design adds a critical security layer—preventing accidental activation or unauthorized power restoration in sensitive operational scenarios.

Built to withstand demanding conditions, this switch features a rugged construction with a compact footprint measuring 4 x 3 x 7 inches, making it ideal for installation in tight quarters where space is at a premium. The removable knob operates via a simple twist-to-OUT mechanism—twist the cap to the OUT position and pull to detach, eliminating the risk of accidental re-engagement during transport or storage. The 300-amp capacity and 32-volt rating handle sustained electrical loads across dual-battery systems, winch controllers, and auxiliary power management in mobile tactical platforms. Its marine-grade specifications ensure corrosion resistance and long-term reliability in salt-spray, moisture-heavy, or extreme-temperature operational environments.

This switch delivers maximum value for equipped vehicle operators, mobile command post administrators, and field technicians managing multi-battery electrical architectures. First responders and military end-users benefit from the security feature—a removable knob prevents tampering and ensures controlled power restoration by authorized personnel only. Installation requires direct inline placement between the positive battery terminal and main electrical bus; the compact dimensions allow mounting in engine bays, equipment racks, or under-dash locations where traditional full-size switches cannot fit. Compatibility spans 12V and 24V systems common in law enforcement vehicles, armored platforms, and expeditionary power supplies.
