ABSTRACT:
A tilt responsive switch supported on a hinged structure such as a trunk lid, door or the like includes an oscillating mass or pendulum rotatingly held by a bearing structure located within the switch housing and a pair or electrical terminals electrically connected by a movable contact mechanism. The pendulum effectively controls the motion of the movable contact mechanism. When the electrical terminals are connected by the movable contact mechanism, the pendulum abuts against a first internal switch housing limit bumper. When the pendulum abuts against a second switch housing limit bumper, the movable contact mechanism is disconnected from the electrical terminals.
