Abstract
Abstract A safety switch for use in a motor vehicle to control the vehicle electrical system. In the event of collision, the vehicle battery will be automatically disconnected from the vehicle electrical system. A trigger mechanism includes a pivotable weight which will move due to the forces of inertia to cause release of a trigger from a plunger mechanism. The plunger mechanism is spring biased to cause disengagement of the vehicle battery with the vehicle electrical system. Upon release of the trigger, the plunger will cause the vehicle electrical system to become inoperative.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
A safety switch for use in a motor vehicle wherein the switch is adapted to render the vehicle electrical system inoperative should the vehicle become involved in a collision comprising a housing, a plunger mechanism mounted in said housing, a trigger mechanism mounted in said housing, said trigger mechanism including a trigger biased into engagement with said plunger mechanism to maintain said plunger mechanism against movement, said trigger having an enlarged head at one end thereof, hook means connected to said enlarged head, said trigger mechanism including a pivotable weighted member and a stem, said pivotable weighted member being mounted on one end of said stem, said pivotable weighted member having a flange means, a weighted mass being mounted on said stem adjacent the other end thereof for pivotal movement by reason of its inertia during collision, said hook means cooperating with said flange means to move said trigger against its bias and out of engagement with said plunger mechanism upon pivoting of said weighted mass and said pivotable weighted member through a predetermined arc during collision thereby releasing said plunger mechanism for movement and rendering the electrical system of the vehicle inoperative.
Claim 2
Dependent Claim
193 words
A safety switch for use in a motor vehicle wherein the switch is adapted to render the vehicle electrical system inoperative should the vehicle become involved in a collision comprising a housing, a plunger mechanism mounted in said housing, a trigger mechanism mounted in said housing, said trigger mechanism including a trigger biased into engagement with said plunger mechanism to maintain said plunger mechanism against movement, said trigger having an enlarged head at one end thereof, hook means connected to said enlarged head, said trigger mechanism including a pivotable weighted member and a stem, said pivotable weighted member being mounted on one end of said stem, said pivotable weighted member having a flange means, a weighted mass being mounted on said stem adjacent the other end thereof for pivotal movement by reason of its inertia during collision, said hook means cooperating with said flange means to move said trigger against its bias and out of engagement with said plunger mechanism upon pivoting of said weighted mass and said pivotable weighted member through a predetermined arc during collision thereby releasing said plunger mechanism for movement and rendering the electrical system of the vehicle inoperative.
Claim 3
Dependent Claim
49 words
A safety switch as set forth in claim 1 wherein said hook means includes three hooks equally spaced about said enlarged head, each of said hooks engaging the flange means associated with the pivotable weighted member, said flange means being a circular plate integral with said pivotable weighted member.
Claim 4
Dependent Claim
84 words
A safety switch as set forth in claim 1 wherein said hook means is supported by clevises formed integrally with said enlarged head, said housing including a seat for said pivotable weighted member, a spring located between said seat and said enlarged head to urge said trigger into engagement with said plunger mechanism, whereby movement of said pivotable weighted member will cause said enlarged head on said trigger to compress said spring to thereby move said trigger out of engagement with said plunger mechanism.
Claim 5
Dependent Claim
48 words
A safety switch as set forth in claim 1 wherein said plunger mechanism includes a plunger spring urged into a position wherein said electrical system of the vehicle will be rendered inoperative, said plunger having a bore therein, said trigger being received in the bore of said plunger.
Claim 6
Dependent Claim
42 words
A safety switch as set forth in claim 4 wherein two compression springs are utilized to urge said plunger into a position rendering the electrical system of the vehicle inoperative, and the position of said weighted mass being adjustable on said stem.
Claim 7
Dependent Claim
46 words
A safety switch as set forth in claim 1 wherein said housing includes a housing section and a telescoping cap portion frictionally engaging said housing section, said telescoping cap portion being removable to permit access to said pivotable weighted member, said stem and said weighted mass.
Claim 8
Dependent Claim
57 words
A safety switch as set forth in claim 1 wherein the elecTrical system includes a battery, one cable of the battery being adapted to be connected to the safety switch, said cable being electrically insulated from the housing, and said pivotable weighted member being semieliptical in shape and being seated in a seat provided in said housing.
Claim 9
Dependent Claim
49 words
A safety switch as set forth in claim 1 wherein said plunger mechanism has an enlarged end thereon, means whereby said enlarged end causes movement of a conducting member to break a circuit when said trigger releases said plunger mechanism to render the electrical system of the vehicle inoperative.
