ABSTRACT:
A vibration sensitive switch has a pair of spaced apart parallel contacts contained within a switch body and a movably supported tubular mass inside a chamber in the body. The mass is supported by conductive men, bets in the form of two pairs of contact bars secured at each end of the tubular mass and located between the two contacts so that both sets of bars are in electrical contact and resting on and between them by force of gravity. The contact bars are suitably arranged to cross each other at the axial center of the tubular mass and angled to provide a wedging action when at rest thus providing higher contact pressure than would normally be obtained.
