PURPOSE: To form an electric passage without passing through an inertial body or the moving element of a sensor responsive to crash by providing a sensitive element moving to a second position in response to a deceleration force exceeding an actuation force. CONSTITUTION: When the deceleration force exceeds a set threshold value, it overcomes the restriction force of a field and a metal ball 34 is shifted in the direction of an arrow A along a passage 40. The metal ball 34 touches the forward end of upper contactors 50, 52 substantially simultaneously. Since the forward ends are insulated, electric contact does not take place at the moment of time. The metal ball 34 is shifted in the direction of arrow A until the contactors 50, 52 are bent in same direction to touch bends 58, 60, respectively. Consequently, an electric paths are formed between contactors 48, 50 and 46, 52. These electric paths are utilized for generation of electric signal which is delivered on conductors 14, 16, for example, to a passenger controller 80. |
