Coin switch sticking

[Jcarter168]

I have an NRI coin mech that only takes dimes and nickels I believe.  The coin switch works but gets stuck when pressed.  If I manually push it up, it will spring back up.  How do I clean/fix one of these?

Sorry it's a sealed micro switch, you can't open it, but you can try some electronics contact spray cleaner & see if it gets inside to help free it up. most the time I've found that the whisker-wire isn't riding in the middle of the coin-paths arc & scrapes the side of the little channel it rides in. if so then some careful bending with a pair of needle nose piers can help true it up.
