Temperature control switch is the Electrical appliances temperature protection the main protection components. Product temperature sensing and speed of response is a very re-parameter. Buy a good product, Is the common aspiration of each customer. Temperature switch on the market today, the price level is different, the difference between the poor, Then the quality standards have a certain gap. So how to determine the KSD301, KSD9700 temperature control switch quality? First of all, we must start from the thermostat principle. To KSD9700 temperature control switch as an example:
KSD9700 temperature control switch working principle:

KSD9700 temperature control switch is the use of bimetal as a temperature sensing element. When the temperature rises to the set temperature, Disc break, Rapid separation of the drive contacts, Cut off the working circuit. When the temperature dropped to normal operating temperature, Disc reset, Contact back to its original state, To the purpose of on-off circuit.
The above product work process, Bimetallic temperature of the temperature, And the reaction rate is an important indicator of temperature control switch. Temperature control switch temperature sensitivity and response to the following factors:
1, the heating power of electrical appliances: to buy products, We must first understand the power of heating appliances, Temperature control switch power and heating power to match, The greater the power of the electrical heat faster, If the temperature control switch power selection is too small, High-power current through the temperature control switch, Temperature control switch itself will be fever, Seriously affecting the product protection speed accuracy, We need to take into account the KSD9700 temperature control switch temperature time, the correct selection of temperature, Temperature switch will be able to sense the temperature fast, Quick action, do not pull the arc characteristics.

2, the installation of temperature control switch:
Temperature control switch installation will also affect the temperature of the product speed. Temperature control switch temperature is to rely on the closure of the plastic surface of the shell,And then affect the internal air temperature, and then passed to the bimetal. Then the installation of temperature control switch, Should make the product close to the electrical heating source. Installation can add some thermal silica gel, Can be more fixed temperature control switch, But also conduction heat, it will not affect the temperature control switch performance.

3. Electrical characteristics of electrical appliances: When the temperature control switch in the use of some of the current and voltage sense of heat than the electrical appliances, You need to consider the electrical characteristics of electrical appliances. The best choice of normal electrical strength: 50HZ, 2000V, 1m no breakdown, No flash Road Of the temperature control switch.
