I know when we first got ours.. It would be out as many times as it worked.. I would spend lots of time bending and adjusting.. Only to have it break the silver y part.....,,,,,,After about 5 new switches... I must of gotten a good batch. NO problems since...
Also when I first changed the switch... I would solder it to long on install. And melt or damage it sometimes... Maybe that could be happening in your experience.. Good luck...
