1. TB02 sudden jump temperature protection switch is a bimetallic temperature protection switch and a new type of temperature protection switch, which is used in the fields of industrial circuits, motors, and household appliances, especially microwave ovens, induction cookers, Dishwashers, electronic disinfection cabinets, electric hot water bottles, water dispensers, soymilk machines, cooling and heating air-conditioning fans, food processors, warm water bags, heat up quickly, foot baths, coffee makers, electric ovens and other small appliances are more commonly used . 2. TB02 sudden jump temperature protection switch is divided into open type and sealed type. The sealed type thermostat is divided into automatic reset type and manual reset type. The models of various sudden jump temperature protection switches are collectively referred to as KSD, and the temperature is fixed and cannot be adjusted. The working principle of the automatic reset type sudden jump temperature protection switch is to make the bimetallic plate into a dish-shaped element, and heat to generate displacement energy accumulation. Once the resistance reverse sudden jump is overcome, the push rod is pushed to quickly break the contact and automatically disconnect the circuit ; When the temperature drops, the bimetal snaps back to its original state, closes the contacts and automatically turns on the circuit, so as to achieve the purpose of controlling the temperature. 3. The automatic reset snapping temperature protection switch is used as the overheat protection of various electric heating appliances. Disposable thermal fuse (also known as over-temperature fuse) is used in series, and the sudden-jump thermostat is used as the primary protection. When the heating element is over-temperature or dry-burning, the sudden jump thermostat will act quickly to automatically disconnect the circuit, and when the temperature drops, it will automatically connect the circuit. The thermal fuse is used as a secondary protection to automatically disconnect the circuit when the sudden jump thermostat loses or fails to cause the heating element to overheat, effectively preventing the burning of the heating element and the resulting fire accident. 4. TB02 sudden jump manual reset type temperature protection switch adds conical spring leaf and manual reset mechanism. When the bimetallic strip is heated and deformed to a certain degree, a sudden jump action occurs. The conical spring strip is pushed by the bimetallic strip and bounces in the opposite direction. The contact is driven by the porcelain rod to quickly break and automatically disconnect the circuit; when the temperature drops, the bimetallic strip The plate returns to its original state, but because the conical spring plate has no automatic reset capability, it cannot rebound and reset, and the contact still does not move. You must press the manual reset button to reset the conical spring plate with the help of external force, and the contact will be closed accordingly.
