Abstract
A battery disconnect device includes a housing with a trip/sense circuit, a sealed solenoid and two bars. The solenoid includes a spring loaded contactor disposed in a sealed chamber which normally bridges the bars and is constructed to provide a very low resistivity between the bars. When a coil of the solenoid is activated, in response, for example, to a low battery voltage, the contactor moves away from the bars and is kept in an open position by a magnet. The contactor can be closed or returned to the original position by a manual push button or by a close circuit operated from a remote switch. Additionally the contactor may be opened by using a remote button to act as an anti-theft device.
