Abstract
An electronic timer graphically displaying programmed ON/OFF settings includes a microprocessor; a time setting unit electrically connected to the microprocessor for a user to set at least one programmed ON/OFF setting for at least one selected day; a memory unit electrically connected to the microprocessor for storing the programmed ON/OFF setting; a clock signal generating unit electrically connected to the microprocessor for generating a clock signal to the microprocessor; and a graphic time scale display unit electrically connected to the microprocessor and including a plurality of time scale segments, each of which represents a predetermined time period. The microprocessor calculates based on the programmed ON/OFF settings to derive all the time scale segments that are corresponding to the programmed ON/OFF settings, and drives the graphic time scale display unit to show the time scale segments corresponding to the programmed ON/OFF settings.
