Abstract: A remote battery switch for motor vehicles provides for the remotely controlled disconnection and connection of the vehicle electrical system, for long term storage or carjacking threats. The switch attaches directly to the side terminal or top post connector of a standard motor vehicle battery, without further need for additional structural attachment. A cord or cable is run from the battery switch to the vehicle passenger interior, and is preferably discreetly accessible by the vehicle operator should the need arise. The cord or cable serves to open the switch by releasing a magnetic contact and withdrawing the magnetic switch bar against a spring, whereupon the switch bar is caught and retained by a double acting catch. A second pull on the cord releases the catch, whereupon the spring pulls the magnetic switch bar into magnetic contact with the other switch point to close the circuit. Thus, the switch may be remotely opened and closed using purely tensile forces in the cord.

The control knob is slidable over the track body, and is alternatively locatable in extended and retracted positions. When the control knob is located in a retracted position, the guide followers are releasably secured in notches contained in the tracks. When depressed, the guide followers are disengaged from the notches, permitting the control knob to move to an extended, operating position. In the operating position, the user depresses the control knob, thereby engaging a second plurality of notches which permit operation of a two-step gas valve by sequentially depressing and rotating the control knob.

Abstract: A high-voltage switching device is provided having an insulating base member mounted to a panel such that a wiper arm assembly of the switching device is accessible from the front of the panel for pivoting a switching member between open and closed positions. Preferably, the switching member is a conductive rod having a portion coiled about a primary terminal assembly of the switch such that a first end of the conductive rod may be pivoted about the axis of the coiled portion between the open and closed positions. Although the switch is intended for high-voltage applications, the conductive rod is of sufficiently small gauge so as to allow for the manual pivoting of the rod without the need of leveraging linkages. The insulating base member of the switching device provides effective electronic isolation of the terminal assemblies and the conductive rod from one another and from the ambient environment of the switch such that a protective insulating housing is unnecessary.
