ABSTRACT:
In response to a deceleration force, a rapidly reacting magnetic system causes a reed switch to change state. A predetermined time after the force ceases, a second, relatively slowly reacting magnetic system causes the switch to return to its original state. Each magnetic system includes a fixed magnet and a magnet movable within a recess. The reed switch is situated in a housing proximate the recesses and is controlled by the positions of the movable magnets. The recess through which the movable magnet of the slowly reacting system moves contains a fluid. This magnet carries a pair of self-positioning members which cooperate with the fluid to regulate the speed of the movement of the magnet within the recess, in accordance with its direction of movement, such that the slowly reacting system maintains the switch in the changed state and, thereafter, returns the switch to its original state.
