ABSTRACT:
A thermosensitive switching circuit includes a first voltage divider for producing a reference voltage with a predetermined constant level and a second voltage divider for producing a detection voltage signal whose level changes in response to changes in the temperature to be detected. The reference voltage is compared with the detection voltage signal by a voltage comparator having an open-collector type output circuit, and a feedback resistor is connected between the output terminal and the input terminal of the voltage compartor to provide hysteresis for the comparing operation of the voltage comparator.
