A tilt angle sensor has a body which includes a V-shaped cavity defined by a pair of inclined surfaces which intersect to define a lower end. A roller is disposed in said cavity. A sensing circuit is associated with the cavity to sense the presence of the roller in the lower end of the cavity. The sensing circuit initiates a first signal when the roller is displaced from the lower end of the cavity. A timing circuit is coupled to the sensing circuit for commencing a timing cycle upon the occurrence of the first signal and for providing a second signal after a predetermined time delay. A latch mechanism coupled to the timing circuit latches an output device upon the occurrence of the second signal.
