ABSTRACT:
The specification discloses a timer including a housing having a display aperture in the front surface thereof. A light emitting diode display is mounted within the display aperture for displaying multiple digits. A U-shaped bracket pivotally connects to the housing and has a base surface which is adapted to be attached to a telephone set for ease of viewing by the telephone user. Timing circuitry within the housing generates periodic timing signals and drives the display to display time intervals to the telephone user. A switch is positioned on the housing for actuation by the telephone user to start and stop operation of the circuitry.
