ABSTRACT:
An acceleration sensor that includes a permanent magnet mounted for movement within a cylindrical cavity in a body of non-magnetic material. The magnet has a cylindrical geometry and an outer surface with a first portion of electrically conductive construction entirely around the magnet adjacent to one axial end thereof, and a second portion of electrically non-conductive construction entirely around the magnet adjacent to an opposing end thereof. A pair of diametrically opposed electrical contact leaves extend through openings into resilient sliding contact with the magnet. The magnet is resiliently urged toward one end of the cavity such that the contacts are in engagement with one of the first and second surface portions. Acceleration forces on the magnet move the magnet toward the opposing end of the cavity, bringing the contacts into engagement with the other of the first and second surface portions, such that motion of the magnet within the cavity results in a change in electrical conductance between the contacts.
