Abstract:
An illuminating circuit for the key slot in a locking device is made up of a high intensity light source which is mounted on the face plate of the lock in close proximity to the key slot, a piezoelectric crystal is mounted within or adjacent to the lock to respond to vibrations created, for example, by tapping on the face plate to generate an electrical signal, and a control circuit including a timer and battery respond to the electrical signal generated by the crystal to energize a light source for a predetermined time interval after receiving the electrical signal from the crystal.
