The bimetal temperature control switch is most widely applied due to low cost and simple assembly, adopts a bimetal element as a temperature sensing element, and is manufactured by rolling two metal materials with greatly different thermal expansion coefficients according to a special process. When the electric appliance works normally, the bimetallic element is in a free state, the contact is in a closed/open state, when the temperature rises to an action temperature value, the bimetallic element is heated to generate internal stress to act rapidly, the contact is opened/closed, and a circuit is cut off/connected, so that the thermal protection effect is achieved. When the temperature drops to the reset temperature, the contact is automatically closed/opened, and the normal working state is recovered.
Referring to fig. 1 for a specific structure of a common temperature switch at present, the common temperature switch comprises a shell 1, an upper cover 2, a cross spring 7, a bimetallic element 3 and a height ring 8 which are sequentially arranged in the shell 1, wherein after the cross spring 7, the bimetallic element 3 and the height ring 8 are sequentially stacked from the bottom wall of the shell, a contact on the cross spring 7 corresponds to a contact embedded on the height ring 8, the bimetallic element 3 is attached to the cross spring 7, one path of an external circuit is connected with the shell, and the other path of the external circuit is connected with a contact on the height ring 8. So that when the bimetal element 3 senses the change of the external environment temperature, the bimetal element can drive the contact on the cross spring 7 to be connected with or disconnected from the contact on the height ring 8, and in the process, the cross spring 7 deforms to provide a resetting effect for the two contacts.
