ABSTRACT:
A pushbutton assembly has an actuating arm with a body portion and an outer end portion connected to the body portion by a narrowed portion. A pushbutton having a cavity and a slot leading from the rear wall to the cavity is retained on the arm by slipping the arm through the slot until the end portion enters the cavity, then twisting the end portion slightly around the longitudinal axis of the arm. The pushbutton can be released by realignment of the arm end portion with the body portion.
