摘要： A temperature control device is disclosed that includes a heating wire being connected to an alternating current power source though a SCR, a sensing wire being disposed parallel to the heating wire, a thermo-sensitive resin insulating the heating wire and the sensing wire from each other and changing its impedance according to a change in temperature, and a temperature sensing unit outputting a temperature control signal to turn the SCR on or off according to a change in electric current flowing through the thermo-sensitive resin, in which the SCR is turned on or off by a sensing unit diode. The heating wire is heated by a heating current that flows in a heating cycle only, in which a forward voltage is formed in the SCR, and the sensing wire conducts a sensing current that flows in a sensing cycle only, in which a reverse voltage is formed in the SCR.
