Abstract
The switch assembly comprises a single inertial sensing mass which is magnetically biased to an initial position along a path of travel within an enclosure. In this position, the mass holds a normally closed arming switch open. A normally open discriminating switch is disposed in the path of travel of the mass to be closed by the mass upon the occurrence of a velocity change indicating that a passive occupant restraint device such as an air bag should be deployed. Travel of the mass from the initial position releases the arming switch before the discriminating switch closes.
