How to use various temperature control switches?

Apr 19 , 2023

With the gradual development of technology, household appliances are becoming increasingly diverse and intelligent, and the ultimate requirement for any type of household appliance is always safety. The temperature control switch is an important electronic component in electrical equipment, which can also be started or closed as the temperature changes during operation. The temperature control switch is directly connected in series to the electrical equipment to control the electrical equipment, So how to use the specific temperature control switch? What else is worth our attention?

 

How to use the temperature control switch?

The usage of different types of temperature control switches is also different. Here are some examples of temperature control switch models:

 

1. Mechanical temperature control switch: Two types of metal with different expansion coefficients are pressed together. When the temperature changes, the bending degree of the metal will change. When the bending reaches a certain degree, the circuit will be turned on or off. Generally, electrical appliances are thermally protected. For example, when used in electrical appliances, abnormal electrical appliances cause temperature increases, such as water dispensers, electric kettles, and other dry burning causes temperature increases. KSD301 temperature control switches can be used for such appliances; For example, if the motor of soybean milk machine is overheated due to locked rotor, the temperature control switch will start protection, disconnect the circuit in time, and protect electrical safety and personal safety.

 

2. Electronic temperature control switch: Resistance made of platinum, copper, tungsten, and semiconductors (thermistors, etc.) is used for measurement to achieve an ideal temperature control effect. It is widely used in floor heating and air conditioning, and the method of over-resistance measurement can fully utilize the advantages of electrical resistance to control temperature.

 

Precautions for using temperature control switches

When using a temperature control switch, it is necessary to place the metal cover tightly against the mounting surface of the controlled device. In order to achieve a good temperature sensing effect, it is best to coat the temperature sensing surface with thermal conductive silicone or other media with thermal conductivity. During use, the interior of the temperature control switch cannot penetrate into liquid, crack the housing, or arbitrarily change the shape of the external terminals of the switch, thereby avoiding affecting the electrical reliability of the temperature control switch. At the installation site of the switch, insulation protection measures should be taken to prevent electrical accidents due to leakage.
