Abstract
This miniature omnidirectional impact switch has a generally cylindrical electrically conductive mass held by coil spring bias in abutment with a conductive header wall at one end of a cylindrical housing. The mass has a blind bore in one end. The mass is held axially tilted by contact between a free end of a wire conductor and an end wall of the bore. A closed circuit is defined between a second conductor contacting the header wall and the first conductor, via the mass and header wall. The switch is responsive to an impact applied to the other end of the housing or to a side thereof within 200 microseconds after impact to open the closed circuit by separating the mass from the header wall and the end of the first conductor against the spring bias. A movement of the mass of 0.001 of an inch is sufficient to open the closed circuit.
