Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
328 words
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.
Claim 2
Dependent Claim
328 words
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.
Claim 3
Dependent Claim
62 words
The remote battery switch of claim 1 wherein: said switch contact comprises a channel configuration including a magnet therein, and said battery attachment terminal includes at least a switch contact portion formed of ferrous magnetic metal, whereby; said magnet is attracted to said ferrous magnetic metal switch contact portion to provide positive closure and electrical current flow when said switch is closed.
Claim 4
Dependent Claim
35 words
The remote battery switch of claim 1 wherein: said switch secures directly to a battery by means of a single attachment to one battery terminal, and is devoid of additional structural and electrical battery attachments.
Claim 5
Dependent Claim
30 words
The remote battery switch of claim 1 including: means providing for the universal attachment of said remote battery switch to a battery having either top post terminals or side terminals.
Claim 6
Dependent Claim
116 words
The remote battery switch of claim 1 wherein: said double acting catch includes a notch therein and is disposed at least partially within an arc defined by movement of said switch contact, and; said switch contact fastener includes a spring thereon serving to resiliently urge said switch contact against said cable attachment terminal, whereby; said spring connection end of said switch contact is displaced from an arcuate path upon contacting said double acting catch, and said spring connection end of said switch contact is captured and retained within said notch of said double acting catch by means of said switch contact fastener spring, and is further released by means of further tensile pull upon said cord.
Claim 7
Dependent Claim
42 words
The remote battery switch of claim 1 wherein: said battery attachment terminal and said cable attachment terminal each include an extension, with each said extension respectively being at a substantially right angle to said battery attachment terminal and said cable attachment terminal.
Claim 8
Dependent Claim
140 words
The remote battery switch of claim 6 wherein: said battery attachment terminal includes a terminal post clamp adaptable to a battery top post, with said battery attachment terminal extension including a side terminal connector adaptable to a battery side terminal, and; said cable attachment terminal extension includes both a side mount cable terminal attachment and a post mount cable terminal attachment, whereby; said remote battery switch provides for universal connection to a battery having top post terminals by means of said terminal post clamp of said battery attachment terminal and said post mount cable terminal attachment of said cable attachment terminal extension, and further provides for connection to a battery having side mount terminals by means of said side terminal connector of said battery attachment terminal extension and said side mount cable terminal attachment of said cable attachment terminal extension.
