The magnetic control switches used in refrigerators are mainly divided into two categories: low-temperature magnetic control switches and ambient temperature magnetic control switches. Their function is to automatically control the on and off of the low-temperature compensation heater to ensure the normal operation of the refrigerator in a low-temperature environment. It is mainly divided into the following two categories
(1) Low-temperature magnetic control switch
Installation location: Usually installed in the freezer.
Trigger condition: When the temperature in the freezer rises above the set conduction temperature, the switch contact closes, connecting the compensation heater circuit.
Typical parameters: The conduction temperatures vary among different brands. For instance, the disconnection point of some models is 9℃ and the conduction point is 11℃.
(2) Ambient temperature magnetic control switch (Ambient temperature type)
Installation location: Generally located on the top frame or door hinge of the refrigerator, it is used to detect the ambient temperature.
Trigger condition: When the ambient temperature is lower than the set value (such as 10℃ to 16℃), the switch contact closes and the compensation heating is initiated.
Typical parameters: The conduction point of some brands is 10.2℃ and the disconnection point is 12.2℃.
