  • Inertia sensor
    Patent number: 4815320
    Abstract: An inertia body moves from a rest position in response to an applied acceleration and in so doing operates an electrical switch remote from the rest position. The body moves on spaced rails of a track arranged in a plane, with an aperture between the rails so that the body can extend below the running surfaces of the rails. The plane may be inclined and/or the rails may be non-parallel so that the center of gravity of the body rises as it moves from the rest position.
