What is a temperature fuse
Temperature fuses, also known as thermal fuses or thermal melt fuses, are safety devices used to protect circuits or equipment. They are specially designed resistance wires that can automatically disconnect the circuit based on the magnitude of the current and the duration of time, serving the purpose of overload protection.

The working principle of temperature fuses
When current flows through a conductor, the conductor will heat up due to its certain resistance. The amount of heat generated follows this formula: Q=0.24I2RT; where Q is the amount of heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time the current flows through the conductor; from this formula, we can easily see the simple working principle of a fuse.

What is used to sense temperature in a temperature control switch?
Many friends are very interested in what temperature sensing the snap-action temperature control switch relies on! Since it is a snap-action temperature control switch, it must have its own temperature sensing system. Without a good temperature sensing system, it is impossible to predict the temperature.
