These have got to be the lowest quality switches I've ever tried to use! Rather NO quality! It seems that even if you approach them with a soldering iron, it's all over! I only succeeded on the third attempt/change. I've dabbled with electronics my whole life, including some pretty thin circuit boards, and I've never had a problem like this! It's a shame that resources are so limited when it comes to this type of switch. Don't be disappointed, find something else!
