Description

Technical Field

[0001] The utility model relates to the technical field of power-off reset, in particular to a power-off reset device for a temperature controller. Background Art

[0002] Thermostat is a common device used in our daily production and life. Various heating or cooling devices are controlled by thermostats, which can well adjust the temperature in our production and living environment. In actual use, the thermostat is usually not disconnected from the plug or other devices, because if it is disconnected and unplugged each time, it will cause subsequent use to be more troublesome.

[0003] Therefore, in some equipment that needs to be powered off, such as large heating or cooling equipment, it is necessary to completely ensure that the device will not be accidentally started by cutting off the power, so as to meet the requirements of production safety. Therefore, the thermostat needs to have a convenient power-off and reset device structure to ensure production needs during use, while also avoiding the trouble of plugging and unplugging the plug switch.

[0004] At the same time, when the existing connecting switch is used, due to long-term wear or metal fatigue and other conditions, the contact points of the switch connecting structure inside the device may not be connected tightly enough, thereby affecting the normal use of the thermostat and requiring replacement or disassembly, which is inconvenient.
