1. What’s the difference between creep action thermostat and snap action thermostat?

According to the action type of contacts, the bimetal thermostat can be divided into creep action and snap action thermostat. General speaking, creep action thermostat can only be used for heating pad or cushion. Our WAA2 series thermostat belongs to creep action type.The function of creep action thermostat is for temperature adjustment, not for heating or over temperature protection. Only USA and Canada accept this kind of temperature controlling device. In Europe,creep action thermostat is not allowed to use. On the contrary, most of bimetal thermostats are snap action. The main purpose is over heat protection. Our KW model is snap action.

2. Why does the smaller size thermal protector have higher price?

Customers like to ask the question:” Why does the smaller size thermal protector have higher price?” It sounds that it does not make sense. In fact, there are some reasons:

1). For the small size thermal protector, all parts have to be more precise. It means that we need to use better manufacturing machineries. The equipment cost would be higher.

2). The yield rate of smaller size thermal protector is lower than common size. So, the final cost would be higher.

3). The material of small size thermal protector is different also. The material has to be more reliable. Accordingly, the price of raw material is higher.

4). For the small size thermal protector, we have to use different machineries and manufacturing process. Both the manufacturing cost and labor cost are much higher than common size.

Due to the above reasons, the final cost of smaller size thermal protector is higher than common size.

3. Why is the thermal switch with lower temperature but higher price?

There are three reasons for thermal switch with lower temperature but higher price:

1). Thermal switches with lower temperature have to use some special materials, like bimetal strip and contacts. These materials have higher cost and better quality level;

2). In the process of manufacturing, both production and testing equipment for lower temperature thermal switches are different. The equipment cost of low temperature is higher than common temperature ratings.

3). The production yield of low temperature thermal switches is lower than standard temperature rating also. It would make the final cost is much higher.

4. How can we conduct the incoming test for your thermal switch?

Incoming test for thermal switch includes temperature test under No-Load, mock-up test under load, functional test in applications and appearance inspection. Since mock-up test, functional test and appearance inspection can be easily done in the customers’ factories, we will only explain how to conduct temperature test under No-Load here.

1). Put the thermal switch inside of a test oven. The air flow speed of the oven needs to be over 200m/min

2). The measuring thermal couple should be as close to thermal switch as possible. An indicator of showing ON/OFF should be provided. The current flowing through thermal switch is less than 0.01A

3). Increasing the air temperature inside of the oven slowly. When air temperature increases to the 10C lower than the bottom tolerance limit of rated temperature value, the further temperature increasing speed has to be controlled at 0.5K/min.

4). When the temperature reaches the tolerance of thermal switch, the bimetal will actuate the contact and cut the circuit off. After that, the operator can open the cover of test oven and let the temperature decrease down. Then, the thermal switch will turn ON again.
