carusoam Posted December 22, 2019 Report Posted December 22, 2019 Ross has some impressive knowledge that comes out at interesting times... Two part epoxy is often the glue that comes from the double plunger arrangement... Most often when new, the mixture is very clear... When aged, the wet glue gets yellowed.... over time with oxygen intrusion into the package... The reactants get less effective with age this way... Speed of reaction is also highly dependent ambient temperature... Often, the instructions on the package will give some direct hints at what temp is best for the reaction to occur... Appropriateness(?) of use... will it glue the specific plastic that needs to be fixed? Is sometimes listed on the package as well.... Expect that the switch parts are made of ABS... acrylonitrile (acrylic ?) butadiene (rubber ?) styrene... all chemically attached in the polymer chain... So... Alexa says... epoxy and PE and PP are a NoGo... but epoxy and ABS seems to be acceptable... Ross, great suggestions... the 3M glues come in a few varieties including one for PP and PE... PP (private pilot, not polypropylene) thoughts only, not a glue expert... or chemist... Best regards, -a-

And by “interesting times” do you mean Post hoc?... after the fact?...too late to be remedied?... They call me Mr. Whatyoushouldhavedone.
carusoam Posted December 22, 2019 Report Posted December 22, 2019 Ross, impressive knowledge... all the deep, factual, tech details about aviation... combined with similar tech details with depth regarding areas outside of aviation.... Interesting times.... whenever the non-aviation knowledge applies directly to MS aviation topics... It’s enjoyable to be part of this community... I probably could have wrote my initial post a bit better... I struggled with a triple post at first... something locked up on my WiFi... Then I rushed to get the post pasted without its brothers.... Best regards, -a- 1
LANCECASPER Posted December 22, 2019 Report Posted December 22, 2019 As a dentist can you just put a cap on the switch cover . . Nevermind, that would be thousands of dollars . . Lol . . Jk 1

LANCECASPER Posted December 22, 2019 Report Posted December 22, 2019 I would never have thought of going to a dentist for a chipped switch cover. I wonder if I should see a proctologist the next time my exhaust system needs work. 3

enginenerd Posted October 27, 2025 Report Posted October 27, 2025 Bump on this old thread. I just broke mine today. I have the piece so I may glue it. That said, my switch was noticeably getting stiffer before it broke. In fact, sadly, I thought about this about 1 flight before, wondering to myself why that switch was getting sticky. On the very next flight, crunch, broken. With that said, has anyone attempted to clean and lubricate the actual switch mechanisms when they get sticky? I would say this one in particular is 2-3x as hard to toggle as the "normal" ones and that feels like the root cause of the cover failure- it really shouldn't be hard to push. Maybe a good blast with contact cleaner and then a light lube? The switch / switch cover appears to be hard to get at the moment.
N201MKTurbo Posted October 27, 2025 Report Posted October 27, 2025 Yes, shooting lubricant into the switch where the rocker goes through will do wonders. Some are sealed with a rubber seal, if so, get a pin or poker and carefully push the seal aside without damaging it and shoot some lube in next to the needle. The lube will get to the right place.
N201MKTurbo Posted October 27, 2025 Report Posted October 27, 2025 The switches were designed to last a long time. Our planes were designed to last longer.
