Common issues with micro switches

One possible reason for poor contact of the micro switch may be the adhesion of dust to the copper sheet or switch contacts. It is recommended to use sealed electric switches. Another reason is damage caused by harmful gases in the natural environment, which leads to the formation of insulating film layers on the surface of the joint. It is recommended to use joint materials with good adaptability to the natural environment, such as gold and aluminum alloys.

Even if the micro switch is pressed, the load may not be turned on. There are many reasons for this problem. It may be due to poor contact, joint dissolution, or damage to the internal structure of the twisted spring. It may also be due to different operating speeds or frequencies of the operation process, or it may be affixed to waste, dust, etc. The actual reason must be checked.

There may also be problems with the aging and burning of the insulation layer of the micro switch. Firstly, the key to aging and corrosion of the micro switch is due to the large volume of the load, which then leads to the electrical isolation and floating of the joint in the surrounding area. This situation can be avoided by the load switching of the automotive relay and AC contactor. High humidity in the environment leads to noticeable changes in temperature nearby, causing water droplets to seep in and increase the carbonization of the insulation layer. In humid and cold natural environments, it is best to avoid the long-term presence of micro switches or to use sealed switches.

If there is suspicion of a problem with the micro switch, it should be replaced as soon as possible to avoid affecting the normal use of electronic products.
