FAQ

1. What’s the shipping term of bimetal thermal switch?

A: Since all our bimetal thermal switches have small size, the shipping term should be based on the order quantity. If the order is above 50,000 pcs per shipment, the most economical shipping term is by sea. If the order quantity of thermal switch is less than 10,000 pcs per shipment, shipping by express would be the only choice because the weight of 10,000 pcs would be less than 50Kg, MOQ of shipping by air. For the quantity between 10,000 and 50,000 pcs, express or shipping by air is optional, depending on the weight of different thermal switches.

2. What’s the price difference between delivery term Ex works and FOB?

A: The cost difference between delivery term Ex Works and FOB for our thermal switch is around USD 270 per shipment. Therefore, if we quote the price under Ex works, and you want us to offer FOB price, we will add USD 180 to each shipment.

3. What’s the advantage of using automatic equipment to produce thermal switches?

Comparing to traditional manual equipment, automatic equipment is more precision, consistent, reliable, faster, and safer in producing thermal switch. When conducting temperature calibration, the auto equipment can control the strength and movement of calibration pin precisely, and avoid operator’s occasional mistakes. During the process of bimetal temperature selection and temperature testing, it is much faster and can save 90% human power. For bimetal and contacts welding processes, the automatic equipment is obviously more reliable.

Because of the above reasons, we are using automatic equipment to produce most of our thermal switch and thermal protectors. Of course, it also has some short comings. It would be difficult for auto facilities to produce customized and small orders. To solve this problem, we remain a complete set of manual operation equipment. It is intended for trial orders or customized products.

4. 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:

a. 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.

b. 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.

c. 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.
