Stem type therostat operates by opening and closing a snap-action switch in the load circuit. It consists of a brass tubing which is the sensor for operating and as soon as the particular temperature is reached the switch opens and thus switched off the mains supply to the load. When the temperature at the brass tube fall below a certain level the switch makes the contact and the mains supply to the element is restored. In this way the temperature can be set by adjusting the screw.
