The Armtech Hybrid Battery Isolator consists of a heavy duty control box that is normally mounted close to the vehicle’s battery. Three remote switches (all supplied) control the unit; two cockpit mounted (one ‘ON’ and one ‘OFF’) buttons are operated by the driver, and an external waterproof ‘OFF’ switch can be operated by the marshals in the event of an accident. Any number of additional switches can be added if required. An indicator light on the unit lights when the unit is armed, as does another attached to the driver operated ‘ON’ switch.

The switches are wired to the unit using low voltage and current cable (not supplied). In the event of an accident where any of the cables are severed the unit will automatically be turned off. A safety sticker sheet and full instructions are also supplied with this Armtech Hybrid Battery Isolator.
