ABSTRACT:
A shock sensor for vehicles is provided with a housing having a sloping bottom wall and a ball that can move up the sloping wall when a shock in excess of a certain level is applied. A supporting member pushes the ball towards the bottom end of the housing but is released from the ball upon the application of a shock in excess of a certain level. A movable electrode is mounted on the supporting member and is disconnected from a fixed electrode that is fixed within the housing during downward movement of the rod. This causes the electric current to be turned off. The connected state of the electrodes can be restored by pulling up a reset member.
