This miniature control circuit employs a microprocessor without using the program motor, cam and limit switch etc. to miniaturize the size. The one port of switches (SW1-10) in the control circuit is connected to ground and the other port connecting pull-up resistances (R1-8) is connected to the input terminal of integrated circuits (IC1, IC2). And the input signal between port (3) and (5) is connected to the input terminal of the integrated circuits through resistances (R9, R10) and diode (D1). Its output port (A) connecting the pull-up resistance is connected to the one port of switches (SW11-13).
