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.
