I have some microswitches that electronically works fine, and the button also works fine. The problem is with the arms. They tend to get slightly stuck and they are not pushed away but the button when depressing. What happens is that the switches do not work consistently. It's very annoying becuase when you check them they look fine, then they work ok for short time, and then you are back with the same problem.
What to do in those cases? Is there a way to fix the arm? I tried gently widening a bit the part of the arm that is attached to the microswitch, but I got poor results. I know a new microswitch is not expensive at all, but it's quite a long process ordering a new one, and then desolder the old one and solder the new one.
Do you have some suggestion on how to fix switch arms not working consistently?
