Q: When and why do we need gold contacts of thermal switch?

A: 1. If you need the contact resistance of thermal switch is less than 15 mOhm, you need gold contacts. The resistance of gold contacts is much smaller than silver contacts.

2. If the rated current of thermal switch is 250 mA or less, Gold contacts are necessary.  It can prevent oxidation of the contacts at low current rating. Oxidation forms an insulation film on the silver contacts and low current does not arc enough to burn off the oxidation.

Q: How is a thermal switch most possibly to fail?

A: The contacts of a thermal switch are the most possible parts to fail. Once the contacts failed to open, the thermal switch would be malfunctioned. There are several possible reasons to cause this failure.

1. Working current is more than the rated current. For example, the rated current is 5A. If you use this thermal switch to a 10A circuit, it would cause the contacts fail to action. Meanwhile, the life cycles would be much less than the rated value also.

2. The thermal switch suffered abnormal pressure. The imposed pressure would make the case of thermal switch distorted. The action room of bimetal would be narrowed. Then, there is no enough space or strength for the bimetal to trip off. The contacts would keep in close status and fail to open.

3. The contact resistance is too big. If so, every cycle of action would generate too much heat. Gradually, the contacts of thermal switch will be burned and failed to action.

Q: What’s the difference between Normally Closed thermal switch and normally open thermal switch?

A: Normally closed thermal switch means that the contacts of thermal switch normally remain closed. When temperature increases to the set value, the contacts would open and cut the circuit OFF.

Normally open thermal switch means that the contacts of thermal switch normally remain open. When temperature rises, the contacts would close and connect the circuit ON.

We now have several models that both Normally Open and Normally Close type are optional, like 17AME, TS01, KW, KSD301, 3MPE, and so on.

Q: Can I get a customized thermal protector from you?

A: Yes. We are providing customized service for our noble customers. If you need a customized thermal protector sample, please kindly tell us the following parameters:

1) Rated voltage and Current

2) Action temperature

3) Dimensional requirements

4)Overloading or Tripping current if needed

5) Application and relevant special demands

6) Potential order quantity.

If the customized thermal protector has the same dimension as our current models, and you only need special parameters, we would not charge any cost for 5 pcs samples. If the requested dimensions are different, we may need to build new toolings for this customization. It would cause extra cost and we can negotiate separately.
