Battery Isolating Switch with Capped Key 100A 12V/24V Marine
The Battery Isolating Switch with Capped Key is a compact, heavy-duty battery disconnect switch designed to safely isolate your boat's electrical system during storage, maintenance, or emergency situations. Suitable for both 12V and 24V DC systems, this marine-grade isolator provides a simple and effective way to disconnect battery power, helping prevent unwanted battery drain while improving onboard safety and security. Comparable models are rated for 100A continuous current with high short-duration surge capacity, making them suitable for a wide range of marine applications.
Featuring a removable PVC-capped key, the switch can only be operated when the key is inserted. Once switched to the OFF position, the key can be removed, preventing accidental operation or unauthorised use. The protective cap helps shield the switch from moisture, dirt, and UV exposure, making it ideal for demanding marine environments.
Its compact panel-mount design makes installation straightforward in boats, caravans, motorhomes, 4WDs, campervans, and other 12V or 24V electrical systems. Whether you're isolating the starting battery, house battery, anchor winch, or other high-current accessories, this battery isolator delivers reliable performance and peace of mind.
