Abstract : An acceleration actuated switch is disclosed which is capable of distinguishing between random and brief acceleration forces on the one hand and sustained acceleration forces on the other hand. The device comprises a stationary electrical contact and a movable contact held in position by biasing means. Sustained acceleration forces in a particular direction will drive the movable contact along a fixed path to a position whereat the biasing means may bring the movable contact into proximity with the stationary contact thereby closing the switch. If the acceleration force is not in the proper direction or is not applied to the switch for a sufficient length of time, the biasing means will return the movable contact to its original position thereby maintaining the switch in an open condition.
