Thermal Switch
A thermal switch is an electromechanical device that is designed to regulate the flow of current by opening or closing an electrical circuit when a certain temperature threshold is reached. It operates by using a bimetallic strip or a thermistor, which expands or contracts with changes in temperature, to trigger a switch mechanism. Thermal switches are commonly used in a variety of applications, including heating and cooling systems, electronic equipment, and safety devices to prevent overheating or overcooling.

FAQ
Q:
What is a thermal switch?A:
A thermal switch is an electromechanical device that opens or closes an electrical circuit when it detects a specific temperature threshold.Q:
What are some common applications of thermal switches?A:
Thermal switches are commonly used in appliances, HVAC systems, automotive engines, and industrial equipment to prevent overheating and ensure safe operation.Q:
How does a thermal switch work?A:
A thermal switch typically contains a bimetallic strip or other thermally-sensitive material that bends or flexes when exposed to heat. This movement triggers the switch to open or close the circuit, depending on the design and application.
