The utility model is characterized in that the periphery of a light-tight rotary plate which rotates along with a clock wheel shaft is provided with slots with equal distance and equal width, and LEDs are fixed on the relevant positions of the rotary plate to rotate along with the rotary plate so as to output light pulse. The control circuit counts the light pulse, and independent control signals at each output end of a readable and writable write memory are outputted according given timing numbers; then an executive device controls the power switch of an electric appliance to be turned on or off.
