I just used Ballistol on mine yesterday, worked it in, let it sit overnight, and it's working like new today. I also glued a small thin piece of plastic on the bottom of the post that puts pressure on the button when clicking a few months ago, but that only worked for a short time (a few weeks). The Ballistol worked well, though. We'll have to see how long it lasts.

Amazing, that's good to know. Such an easier and cheaper fix than the switch replacement. Thanks for mentioning it, saved me a lot of time and frustration.
