ABSTRACT:
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.
