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.

1. A battery disconnect device for an automotive vehicle comprising:a sense/trip circuit that sense a preselected condition of a motor vehicle battery; connecting elements connecting said battery to vehicular equipment; and a solenoid having a coil activated by said sense/trip circuit when said preselected condition is sensed, a contactor associated with said coil and having a first position in which said contactor connects said connecting elements, a second position in which said contactor is removed and a biasing spring arranged to urge said contactor toward said first position and to generate a force between said contactor and said connecting elements to reduce a resistivity between said connecting elements; wherein said sense/trip circuit is constructed to sense a low voltage condition of said battery and to switch said contactor from said first to said second condition in response to said low voltage condition, and wherein said sense/trip circuit further senses a high voltage condition and generates a high voltage indication signal.
