ABSTRACT:
An acceleration detecting system includes a base plate made of non-conductive material and mounted on a moving object. A stationary contact is fixedly disposed on the base plate and is formed of a first plate-like contact portion fixed and electrically connected at a base end thereof to the first connecting terminal, and a second plate-like contact portion fixed and electrically connected at a base end thereof to the second connecting terminal through a resistor element. A movable contact, which cooperates with the stationary contact to constitute an acceleration detecting switch, is electrically connected to the second connecting terminal and floatingly supported on the base plate so that the movable contact can abut against an intermediate portion or free end of the stationary contact. It is possible to reliably detect a failure of conduction between the first and second connecting terminals by monitoring the energization of an energizing circuit including an acceleration switch and particularly, at a coupled portion or junction of the stationary contact.
