The thermostat on an iron works by turning the power to the heating coils on and off. This regulates the temperature of the iron, keeping it at the desired temperature.

Usually, the thermostat is a bi-metallic switch, which moves in response to heat. The knob changes the pressure on the switch, which changes the amount of heat required to turn the switch off.
