A crash sensor switch having a plunger held in floating suspension by resilient springs is movable from a magnetically biased, switch inoperative position to a switch operative position by crash forces in excess of the magnetic bias force. In one embodiment, the switch is closed to operate a safety device when current flows from one spring through a conductive zone on the plunger and to the other spring.


A crash sensor switch, comprising: a chamber having a rearward wall, and side walls; a non-conductive plunger having a longitudinal axis and an electrically conductive zone located along a portion of said axis; means for biasing said plunger toward said rearward end of said chamber in a switch inoperative position; resilient spring means for engaging said plunger and permitting low friction axial and lateral movement of said plunger within a zone of movement, said spring means having an electrically conductive path for electrically contacting said conduc...
