FAQ

 

1. 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.

 

2. What would happen if the working current exceeds the rated value of a thermal switch?

When the end users operate the appliances, the working current might exceed the rated value. If so, what would happen to the bimetallic thermal switch? There are some possible results:

1. The thermal switch would trip off earlier than the rated temperature. The reason is that the bigger current would generate more heat, and the bimetal would sense higher temperature than the rated value. So, it would trip off earlier.

2. The life endurance would be shorter. Bigger current would hurt both bimetal and contacts. There would be flashover between two contacts. If the current is too big, for example, 3 or 4 times of rated value, the two contacts would be stuck and could not open. That would make thermal switch malfunction, or even cause fire.

3. The thermal switch failed to action in few seconds and even burned the insulation sleeving

Therefore, it is very important for the user to operate the thermal switch correctly and try to avoid overloading the thermal switch.

 

3. What qaulity assurance system do you use in your factory to ensure the thermal switch quality?

1. To ensure the quality consistence of our bimetal thermal switch, we got ISO9001:2008 version certification and fulfill the system strictly. In 2012, we started to implement TS16949 system to meet the demands of automotive cusotmers.

2. The life endurance we guaranteed is based on the working enviroment and rating. Different thermal switch has different level, like 10,000 cycles, 30,000 cycles or 100,000 cycles.

3. The defective rate of our thermal switch that we promise to our customer is 100 ppm.
