Frequently Asked Questions About the Use of Micro Switches

It's believed that many customers have encountered common problems about the use of micro switch, and many people do not know how to deal with them. Besides, they don't have the basic knowledge of micro switches. Let's first explain the common problems about the use of micro switches, and understand it together.

1. What is the cause of the poor contact of the micro switch? How to deal with it?

First, maybe the dust adheres to copper sheet, or switch contact, which is recommended to use sealed electric switch. The second is that in the natural environment, the malignant gas damages it, resulting in the formation of insulation performance covering film on the joint surface. It is recommended to use the  switch with the joint raw materials (gold, aluminum alloy, etc.), which has a good adaptability to the natural environment.


2. What is the reason why the load does not open even if the micro switch is pressed?

There are many reasons for this problem. First of all, may be due to poor contact; second, may be melted contacts; third, may be damage to torsion spring in internal structure; fourth, may be different operating speed; fifth, may be operating process frequency; sixth, may be adhesion of waste, dust. All in all, the actual reasons must be checked.

3. What is the aging and ablation of the insulation layer of the micro switch? How to prevent it?

First, the key to the aging and ablation of the micro switch is that the load volume is large, which then leads to arcing, so the joint floats around. This can be avoided by switching loads on car relays and AC contactors. Secondly, the ambient humidity is too high, resulting in a significant change in the nearby temperature, leading to the infiltration of water droplets and the increase of carbonization of insulating layer. In wet and cold natural environments, try to avoid the long-term presence of micro switches, or use sealed switches.

It's believed that you have read the above FAQs for the use of micro switch and also have an understanding. If you have more questions, you can consult Unionwell, we do hope to help you.
