Abstract
Abstract Safety switch apparatus connected to motor vehicle ignition which is automatically disconnected by force of an impact resulting from a vehicle collision, the disconnection being effected by movement of a weight connected to one contact member. Mounts support two contact members and permit movements of the latter to and from each other. Reset apparatus restores contact of said two members by a simple movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
Safety switch apparatus for use on motor vehicles, comprising a housing, a first mount attached to said housing, first contact means having a portion movably extending from said first mount and having a first contact member capable of lateral movement with respect to said first mount, second contact means having another contact member normally contacting said first contact member and having a pivoting member supporting said other contact member, means supported by said housing and supporting said pivoting member for pivotal movement with respect to said housing, a weight connected to said pivoting member that is susceptible to predetermined shock and is adapted to react therefrom by actuating said pivoting member and said another contact member to carry the latter away from contact with said first contact member, and conducting means connected to said contact members to normally establish an electrical circuit through said contact members.
Claim 2
Dependent Claim
146 words
Safety switch apparatus for use on motor vehicles, comprising a housing, a first mount attached to said housing, first contact means having a portion movably extending from said first mount and having a first contact member capable of lateral movement with respect to said first mount, second contact means having another contact member normally contacting said first contact member and having a pivoting member supporting said other contact member, means supported by said housing and supporting said pivoting member for pivotal movement with respect to said housing, a weight connected to said pivoting member that is susceptible to predetermined shock and is adapted to react therefrom by actuating said pivoting member and said another contact member to carry the latter away from contact with said first contact member, and conducting means connected to said contact members to normally establish an electrical circuit through said contact members.
Claim 3
Dependent Claim
39 words
Safety switch apparatus as of claim 1, said extending portion is resilient and connected to said first contact member, and a second mount supported by said housing, said second contact means having resilient means connected to said second mount.
Claim 4
Dependent Claim
26 words
Safety switch apparatus as of claim 1, and switch means supported by said housing and connected to said conducting means and being normally in off position.
Claim 5
Dependent Claim
99 words
Safety switch apparatus as of claim 1, and reset apparatus operably connected to said housing comprising a reset shaft rotatably mounted on said housing, a pusher member fixed to said shaft and normally inoperative and being so positioned as to push against said first contact means when said shaft is rotated to reset position to thereby force said first contact member when said contact members are disengaged, away and spaced from said another contact member to permit the latter to move to position to thereby make contact with said first contact member, when the latter returns to normal position.
Claim 6
Dependent Claim
22 words
Safety switch apparatus as of claim 2, said first mount having means to adjustably hold said first extending portion in predetermined position.
Claim 7
Dependent Claim
35 words
Safety switch apparatus as of claim 2, said means for supporting said pivoting member has an angular support with a hole therethrough, said second contact means extending through said hole and being pivotally movable therein.
Claim 8
Dependent Claim
26 words
Safety switch apparatus as of claim 2 and a support block supported by said housing, said mounts being attached to said block and extending above it.
Claim 9
Dependent Claim
55 words
Safety switch apparatus as of claim 4, and a second mount supported by said housing, said second contact means connected to said second mount, and a resilient member connected to said shaft and to said second mount and being adapted to be put under tension, when said shaft is actuated from normal to reset position.
