Abstract
Abstract An omnidirectional sensor includes a base plate having a rectangularly shaped aperture therethrough. An operating arm is swingably mounted on the plate to one side thereof and spring biased to actuated position. A pair of spring arms extend from the operating arm through the aperture and are normally biased together. A retainer plate seats on the base plate to the other side thereof and includes an aperture aligned with the base plate aperture and also receiving the spring arms. A circular embossed rib surrounds the aperture. A cylindrical seismic mass seats on the retainer plate within the rib and is held against movement by a magnet surrounding a central cylindrical extension which forces the spring arms apart and engages lateral flanges thereof with the retainer plate adjacent the aperture to retain the operating arm against movement to actuated position. Upon tilting movement of the seismic mass under an acceleration pulse of predetermined amplitude and time, the extension thereof is withdrawn from between the spring arms to permit the arms to move together and move through the aperture as the operating arm moves to actuated position.
