Abstract

The invention discloses a switch with temperature control and overheating protection functions. The switch comprises a tubular casing, wherein a partition board is arranged in the middle of the casing and divides the casing into two cavities, and a temperature control assembly and an overheating protection assembly are respectively arranged in the two cavities. The switch has the doubles functions of a temperature controller and a fuse, overcomes the shortcomings that temperature control and temperature protection of the existing household appliances are finished by adopting two sets of independent devices, can effectively reduce the cost, and enables products to be safe and reliable. The switch adopts memory metal to perform temperature control, and the temperature control accuracy and the durability of the switch are prior to the existing double-metal temperature control scheme.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a switch whose contacts are opened or closed due to temperature. Background technique [0002] At present, the temperature control and temperature insurance in the home appliance industry are two different electronic components, which are completed by two separate devices. , complex structure, unstable quality, and high cost, especially small household appliances are very inconvenient to use due to volume limitations. Contents of the invention [0003] The purpose of the present invention is to provide a switch with temperature control and overheating protection functions, which has dual functions of temperature controller and fuse. Small size, simple structure, adjustable temperature, accurate temperature control, safe and reliable. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: ...
