Secure Power Control for Your Vehicle
A discreet black block mounted near the battery, this isolator offers a tactile way to manage your vehicle's electrical heart. The bright red key provides a clear visual cue that the system is live, adding a touch of colour to the utilitarian under-hood space.
Designed for 12V and 24V systems, it suits car owners, boat operators and RV drivers who need reliable power isolation during maintenance or storage. It serves as both a functional tool and a simple deterrent against theft.


02MATERIALS
Durable Brass and Flame-Retardant Nylon
The core of the switch features durable brass contacts, chosen for their resistance to rust and corrosion over time. These are housed within a flame-retardant nylon body that withstands high temperatures, ensuring safety in the hot environment of an engine bay or bilge. The construction is robust, built to handle the daily demands of automotive and marine applications without degrading.
DETAILS
Waterproof Cap and Compact Form
A protective cap covers the keyhole, shielding the internal mechanism from dust and water ingress, which is crucial for vehicles exposed to the elements. The unit itself is compact, measuring 57.5 by 57.5 by 69 millimetres, making it easy to mount in tight spaces. Weighing approximately 138 grams, it is substantial enough to feel secure but light enough not to strain mounting points.
FITMENT
Universal Fit for Negative Terminals
Installation requires terminals with an 8mm diameter hole, connecting directly to the negative cable of your battery. This standard sizing allows it to integrate into a wide range of vehicles, including trucks, ATVs, UTVs, yachts and campers. Whether you are servicing a classic car or maintaining a modern motorhome, the physical interface remains consistent and accessible.
