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 electro-mechanical or electronic chimes.

Abstract: A doorbell detection and playback circuit for a doorbell pushbutton connected to an alternating current power source comprises at least one bridge rectifier circuit coupled to the power source through a diode placed in parallel with the pushbutton. The bridge rectifier circuit generates a signal at a first frequency when the pushbutton is not depressed, and generates a signal at a second frequency when the pushbutton is depressed. A frequency detection circuit is included and is coupled to the signal from the bridge rectifier. The frequency detection circuit further comprises an output responsive to the presence of a signal at the second frequency coupled to a sound generator for playing a ring tone or series thereof.
