company news about What is the difference between temperature fuse and temperature switch

In the strict sense, the temperature fuse refers to the component that can disconnect the circuit when the temperature of the temperature exceeds certain temperature. After the temperature fuse is turned on the circuit, its own internal structure has been damaged. Even when the temperature returns to normal temperature, it cannot be returned, unless the new temperature fuse is replaced. Of course, there is also a temperature fuse that can be returned (PTC resistance), but this is no longer strictly called the temperature fuse.

The temperature switch is an electrical component that reaches a temperature (or temperature range) disconnecting or turning circuit. It can be divided into automatic recovery and manual recovery. No matter which one, it can be used multiple times, not disposable. However, in recent years, a temperature switch that reaches a certain extreme temperature that can be turned on at one time, and the switch itself is no longer returned. The effect of this switch in the limit temperature is very similar to the temperature fuse. right

In summary, thermal fuses are usually disposable, and they have to be replaced if they are broken. The price is cheaper; the temperature switch is mostly reused, and the price is much more expensive than the temperature fuse.
