Quoted from hawknole:OK, I need some help please. I replaced my Shire Y switch with a new switch because the metal Y broke off. I was attempting to adjust the old switch as it was not responding. The new switch worked fine for a couple games and then no response. I fiddled with it a little then got some intermittent response and now back to nothing. Bad switch or something else and if so what? I reseated the closest connector as well.
test with your hand first... also make sure you aren't over tightening the screws as that will cause the switch to bind.
test with finger... then adjust the rotation of the switch when mounted to ensure the armature moves enough to make the switch click. bend forks if needed to get more travel.
