Snap Action Thermal Controls These devices are similar in function to creep action devices in that snap action devices will open and close an electrical circuit based on increases in either temperature and or current. The real difference is that they are produced with specially formed bimetallic elements which produce a wider temperature variation between the point where the thermal control opens and the point at which the device will close. The devices get their name from the “snapping” sound that the bimetallic element makes when it reacts to changes in temperature.
