Date Feb. 18, 1993.An acceleration sensor is used in particular for recognizing an impact experienced by a motor vehicle. The sensor has a spring-mass system (1) with at least one stable original position (4) and one stable deflection position (5). Upon acceleration in the measuring direction, the spring-mass system is initially deflected only slightly out of the original position (4). However, if a predetermined acceleration value is exceeded, then the spring-mass system (1) jumps into the deflection position (5), in which an electrical contact is closed.
