Abstract
Abstract A safety impact switch device is normally connected to the ignition system of a motor vehicle and is automatically disconnected by force of an impact resulting from a vehicle collision the disconnection being effected by movement of a comparatively heavy article connected to a contact member. The switch device is combined with reset apparatus, and one side of a housing provides the basic support for the mounting members that support the actuating mechanism of my device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
A safety impact switch device for use on motor vehicles, comprising a housing, a first and a second angular bracket attached to said housing each having a supporting extension within the interior of said housing, a third angular bracket attached to said housing having a resilient supporting extension within the interior of said housing, first Contact mechanism supported by said resilient supporting extension and having a first contact member, second contact mechanism supported by said second bracket supporting extension having a second contact member normally directly opposite and contacting said first contact member, a weight connected to said second contact mechanism that is susceptible to predetermined shock and is adapted to react therefrom by movement to separate said two contact members from normal position, spring means attached to said weight and supported by said first bracket extension, and conducting means attached to one of said contact members adapted to normally establish an electrical circuit through said contact members when the latter are in normal position.
Claim 2
Dependent Claim
165 words
A safety impact switch device for use on motor vehicles, comprising a housing, a first and a second angular bracket attached to said housing each having a supporting extension within the interior of said housing, a third angular bracket attached to said housing having a resilient supporting extension within the interior of said housing, first Contact mechanism supported by said resilient supporting extension and having a first contact member, second contact mechanism supported by said second bracket supporting extension having a second contact member normally directly opposite and contacting said first contact member, a weight connected to said second contact mechanism that is susceptible to predetermined shock and is adapted to react therefrom by movement to separate said two contact members from normal position, spring means attached to said weight and supported by said first bracket extension, and conducting means attached to one of said contact members adapted to normally establish an electrical circuit through said contact members when the latter are in normal position.
Claim 3
Dependent Claim
93 words
A safety impact switch device as of claim 1, and reset apparatus attached to said housing at a point spaced from and angularly to said three brackets, and having a cam, a shaft attached to said cam and extending outside of said housing, said cam being eccentrically mounted on said shaft and so positioned that it is spaced from said resilient, supporting extension normally, but upon movement bears against said latter extension and is adapted to move the latter and said first contact member to a point spaced from said second contact member.
Claim 4
Dependent Claim
49 words
A safety impact switch device as of claim 1, said second contact mechanism having an elongate portion, said weight being adjustably mounted on said elongate portion, and a screw extending into said weight and normally bearing on said elongate portion to adjustably hold said weight in predetermined position thereon.
Claim 5
Dependent Claim
40 words
A safety impact switch device as of claim 2, and a block mounted on said housing, a retaining member supported by said block and projecting beyond and normally contacting said cam to thereby hold said reset apparatus in predetermined position.
Claim 6
Dependent Claim
24 words
A safety impact switch device as of claim 2, and a handle fixedly attached to said cam shaft and being outside of said housing.
Claim 7
Dependent Claim
64 words
A safety impact switch device as of claim 1, said housing having two oppositely disposed ends, a switch and a box therefor attached to one of said housing ends and extending into the interior thereof, said switch being connected to said conducting means, and a switch button connected to said switch and being outside of said housing and extending through said latter housing end.
