ABSTRACT:
A vibrating push button station to be associated with a standard traffic signal of the kind used to control vehicular traffic at an intersection so that visually impaired pedestrians will be alerted when the pedestrian WALK signal is illuminated after first pressing a push button. The push button station includes an electromagnetic assembly that is adapted to generate a changing magnetic field following the depression of the push button. A magnet coupled to the push button by way of a flexible diaphragm is either pulled towards and repelled or simply released by the electromagnetic assembly as the magnetic field changes. The opposite movements of the magnet relative to the electromagnetic assembly is transmitted to the push button as a vibration so that the hand of a user will receive a tactile indication at the push button when vehicular traffic has been halted.
