Abstract

An illuminated doorbell pushbutton assembly includes a pushbutton assembly that uses a light source, or a plurality thereof to illuminate the pushbutton. The assembly also includes a user-adjustable rotating task light that can be used to direct light to a door lock, a dark step, or to provide a light for identifying keys. A reflector is rotated through an arc to direct light to the area desired by the user. The assembly further includes an electrical circuit that enables the assembly to be installed with electromechanical or electronic chimes.
