An apparatus for sensing vehicular mechanical motion, which includes a motion transducer for sensing a vehicular displacement, and which generates plural groups of transducer signals based on the sensed displacements, with the transducer signals of each group bearing a predetermined relative phase relationship with respect to the transducer signals of the other groups. The plural groups of transducer signals are respectively applied to plural latching switch circuits, each of which is capable of being set to a first motion sensitive output state and latched to a second output state upon the application thereto of a signal from a respective group of signals. Connected to the plural latching switch circuits is a circuit for detecting when all the latching switch circuits are in the second latched output state and for then generating a motion detected signal indicative of the fact that a predetermined vehicular displacement has occured. Also provided is a circuit for setting each of the latching switch circuits to the first non-latched output state upon the initiation of operations which for safety reasons require the sensing of vehicular motion.
