ABSTRACT:
A vandal-resistant push-button actuator which may be utilized in a vandal resistant, remotely programmable voice communications unit capable of being programmed for automatically calling predetermined telephone numbers. The vandal-resistant push-button actuator employs a push-button, a push-button mounting device having a passageway therein for slidably receiving the push-button, and first and second axially spaced apart seals between the push-button and the passageway. The seals absorb transverse blows to a raised portion of the push-button and a lubricant may be disposed between the seals to prevent an adhesive inserted by a vandal from disabling the actuator. The raised push-button actuator may be disposed inwardly of an escutcheon and shaped to form a concave, ring-shaped surface therewith, thus to inhibit damage to the inner surface of the escutcheon from a hammer blow.
