I have a 1981 M20J and I've replaced one or more of the micro switches twice and I've replace the entire switch with new, twice...over the past 8 years. I find it hard to believe this is normal and I'm convinced there is something else going on that causing this ongoing problem. Thoughts? Thanks in advance for your feeback Rick

Here's a new one, at least new to me. Not sure exactly when, but sometime in the last few months I changed my procedure on when I would set trim for takeoff position, and I noticed that occasionally on the ground the thumb switch would be a little "balky", like it would activate in one direction or not the other briefly. It always ended up working eventually in pre-flight, and NEVER did anything weird in-flight. So figuring I learned to fly with manual trim and this wasn't a dangerous situation, I decided to just keep an eye on it to see if I could detect a pattern. Lo and behold, today I was just doing database updates and decided to do some tests. With everything at rest and the Master on, pushing the trim switch did NOTHING, either direction, no matter what I tried. But then something clicked in my head and I thought "well, these yokes are at full rest position (meaning all the way forward), which is a totally non-flying position. What happens when I pull them back a more neutral flying position?" Voilà, as soon as the yoke was in a more natural flying position, the trim switch worked immediately in both directions, no hesitation, no problemo. So it seems as though there is a limit switch that deactivates the trim button when the yokes are too far forward, but I couldn't find anything about this in the POH. Has anyone ever heard of this? On the long-bodies, the yokes at rest do go all the way to the forward stops, unlike the mid- and short-bodies where there is a mechanism that keeps them in a more neutral position. Perhaps in all my prior pre-flights in two years of owning this airplane I always had the yoke pulled back somewhat which is why I never noticed it. Or perhaps there is still something wrong that I need to keep investigating. Any thoughts?

looking for a KFC 200 trim switch P/N 200-01902-0002 (Why cant this be repaired - are mico switches really that old?) thanks Hendrik
