We all know about the thermal switch normally open and how they are used in electrical appliances, but have you ever thought about what a thermal switch is? If not, don’t worry, this article will help you learn more about them.
What is Thermal Switch
A thermal protector, sometimes known as a thermal switch, is a gadget that is temperature- or current-sensitive. The temperature switch uses a bimetallic strip as a temperature sensing element. When the electrical appliance is working normally, the bimetallic strip is in a free state and the contacts are in a closed/open state. When the temperature rises to the operating temperature value, the bimetallic strip Components are heated to generate internal stress and act quickly to open/close contacts, cut off/connect the circuit, and thus play a role in thermal protection. When the temperature drops to the reset temperature, the contacts will automatically close/disconnect and return to normal working conditions.
The role of the temperature switch
The temperature switch is a temperature switch that uses a bimetallic strip as a temperature sensing element. When the electrical appliance is working normally, the bimetallic strip is in a free state and the contacts are in a closed/open state. When the temperature rises to the operating temperature value, the bimetallic strip Components are heated to generate internal stress and act quickly to open/close contacts, cut off/connect the circuit, and thus play a role in thermal protection. When the gradient drops to the reset temperature, the contacts will automatically close/disconnect and return to normal working conditions.
According to the temperature change of the working environment, physical deformation occurs inside the switch, thereby producing some special effects, and a series of automatic control elements that produce conduction or disconnection actions, also called temperature control switches, temperature protectors, and temperature controllers, referred to as thermostat.
The temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect.
