PURPOSE:To simplify constitution by permitting an AC voltage to control a controlled part at a prescribed mode when work or a work mode by means of a waveform work part is detected. CONSTITUTION:The waveform work part 14 works an AC voltage waveform from a power source 12 and impresses the waveform on a rectifier smoothing part 16, whereby it supplies the waveform to a driving part 18 as a DC voltage. On the other hand, a detection circuit 20 detects whether the voltage waveform impressed on the rectifier smoothing part 16 is worked or the mode of work. When the detection circuit 20 detects work, a signal circuit 22 outputs a detection signal corresponding to the content of detection. The detection signal is transmitted to a control circuit 24 and the driving power of a load 26, being a controlled part which is transmitted from the driving part 18 is controlled and the operation of the load 26 is controlled. Thus, the control part can be controlled without providing a private control signal generation device ad a private signal line. |
