ABSTRACT:
An electric load control device of a heating unit of a heating blanket comprises an actuating unit; a power supply for supplying power to the device; a microprocessor as a control center of the device for generating at least one pulse signal; the microprocessor being actuated by the actuating unit; and a driving unit; the driving unit receiving the at least one pulse signal from the microprocessor for actuating the heating unit to generate heat to heat the heating blanket; the driving unit serving to actuate the heating unit. An actuation time period of the heating unit is controlled by the pulses from the driving unit. In the driving unit, the negative parts of the pulses from the microprocessor are converted into positive pulses so that all the pulses become positive pulses; after the pulses pass through the driving unit, only selective positive pulses are passed.
