I believe many friends have encountered common problems about the use of microswitches. Many people don't know what to do and how to deal with them. They don't know much about the basic knowledge of microswitches. Let's explain the common problems about the use of microswitches first, and let's learn about them together.
1. What is the reason for the poor contact of the microswitch? How to deal with it?
One may be the dust adhering to copper sheets and switch contact points. It is recommended to use sealed electrical switches. The second is the damage of malignant gases in the natural environment, which leads to the formation of insulation coating on the surface of the joint. It is recommended to use the raw materials of the joint (gold, aluminum alloy, etc.) with good adaptability to the natural environment.
2. What is the reason why the load will not open even if the microswitch is pressed?
There are many reasons for this problem. One may be due to poor contact, the second may be due to the dissolution of the joint, the third may be due to the damage of the torsion spring of the internal structure, the fourth may be due to different operating speeds, the fifth may be due to the frequency of the operation process, and the sixth may be attached to waste, dust, and the actual reasons must be checked.
3. What is the aging and ablation of the insulation layer of the microswitch? How to prevent?
First of all, the key to the aging and corrosion of the microswitch is that the load volume is very large, and then lead to electric isolation, and the connector floats around. This situation can be avoided by switching loads of automotive relays and AC contactors. 2. Too high environmental humidity leads to obvious changes in the nearby temperature, resulting in the infiltration of water droplets. Cause the carbonization of insulating layer to increase. In wet and cold natural environment, try to avoid long-term existence of microswitch, or use sealed switch.
I believe you can also understand the common problems about the use of microswitches after reading the above. If you have more questions, you can also consult us. I hope it can be helpful to you.
