How do thermal cut out switches work?
Also question is, what does thermal cut out mean?
Definition of thermal cutout. : a protective device for automatically opening an overloaded electrical circuit because of excessive rise of temperature.
Subsequently, question is, how do temperature switches work? As the switch begins to increase in temperature, the bimetal heats up until it reaches the temperature where it deflects and thereby opens the electrical contacts. When the temperature decreases, the bimetal returns to its original shape and closes the electrical contacts.
In this regard, how do I know if my thermal switch is working?
Touch the leads on your digital multimeter to both sides of the thermal overload switch. Watch the needle on the digital multimeter display to determine if your thermal overload switch needs to be replaced. A functional thermal overload switch will cause the needle to move to "0".
What is thermal protection switch?
Thermal switches and thermal protectors are thermally-actuated electro-mechanical on/off switches. They differ from thermal fuses as they are reusable, and suited to protecting against temporary situations that are common and user-correctable.
