ABSTRACT:
This invention relates to a sensor suitable for detecting the collision speed of a car or the like. The sensor has a pair of spring members which are supported so as to intersect with each other between free ends and fixed ends thereof, a mass which is supported in the intersecting portion of the spring members, and electric contact members which are arranged at an operative position of the mass. When an intense impulsive force acts, the mass moves onto the operative position side against the springs while shifting the intersecting portion of the springs. In the process of the movement of the mass, the collision speed is detected.
