I’m reporting back, just in case anyone stumbles into this topic in the future.
I was able to fix my flaky leaf switches and take them from ~25% reliable to 100% reliable. All it took was two steps:
- I roughed up the contacts of the leaf switch a tiny bit with an emery board.
- I cleaned the contacts with a little 99% IPA on a q-tip.
I don’t know if the important action here was more about cleaning the surfaces with the abrasive and the IPA (they were unused, but had been sitting on the shelf for a few years) or more about roughing the surface to improve contact. But either way, it made a huge difference. Everything is A+ now.
