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.

A remote battery switch for motor vehicles having an electrical storage battery, said switch comprising:

an electrically insulating base plate having an electrically conductive battery attachment terminal and an electrically conductive cable attachment terminal extending therefrom;
said battery attachment terminal including means providing for the direct attachment of said switch to an electrical battery disposed immediately adjacent thereto;
said cable attachment terminal including an electrically conductive switch contact pivotally attached thereto, with said switch contact comprising means for the electrical connection of said cable attachment terminal with said battery attachment terminal when said switch contact is in a closed position;
said switch contact including a spring connection end having a spring connected thereto, with said spring further being affixed to said base plate and providing a tensile force urging said switch contact to a closed position;
a double acting catch secured to said base plate and positioned to engage said spring connection end of said switch contact, with said catch providing means for the retention and release of said spring connection end of said switch contact, and;
a cord having a first end secured to said spring connection end of said switch contact and an opposite second end terminating at a location remote from said first end, with said cord providing means for the application of purely tensile force for the electrical disconnection and connection of said switch, whereby;
a tensile force is applied to said second end of said cord to pull said switch contact clear of said battery attachment terminal to open said electrical connection, and said double acting catch retainingly engages said spring connection end of said switch contact to hold said switch contact in an open position until a second tensile force is applied to said second end of said cord, to cause said double acting catch to release said spring connection end of said switch contact and said spring pulls said switch contact into a closed circuit position against said battery attachment terminal.
