Abstract
An omnidirectional optoelectronic acceleration pick-up for the automatic actuation of passenger safety devices in motor vehicles during emergency conditions, utilizes an inertial body which is held in its rest position by an annular permanent magnetic. When a preset amplitude of acceleration is exceeded, a quasi digital switching behavior is achieved by a radially opening annular gap between the end face of the inertial body and the surface of the annular permanent magnet turned towards that face.
