Hi guys,
just a couple days ago i finally figured out how to open the SafeFlight Stall Switch (since mine din't really want to work).
Because I stepped across a lot of posts regarding the switch, going from who is able to do a overhaul to where to buy anew one, I wanted to share my experience so that if somone is interested to try on his own at least he knows where to start from .
So, for anyone that has not seen it before....This is the Stall Switch, costs over $1000 if someone wanted to buy one.
If you want to do it by yourself, the worst that could happen is you destroy something that also didn't work before...
To get the switch housing apart, you first have to remove both rivets (red arrow) that hold the outer housing to the mounting plate (white in my case). After you separated it, you can proceed with removing also both rivets (blue arrows) that hold the switch to the outer housing. Removing the rivets means you have to physically destroy them.
so basically if you want to get to the core you need to push two small pins on both sides inwards. After that, there is another one on the back (blue arrow) that also has to be pushed in. Be careful not to push them to far inside, or you won't be able to pull them out (that's what happened to me..).
if you got so far, well....you basically did it. Here you can see how it looks from the inside. It's made up from a single copper switch that also functions as a leaf spring (see the bended parts on both sides). In my case I had to clean a bit the contacts since it probably didn't work due to corrosions on the tips.
After the work inside is done just put the lid on it, push the pins in and seal it with some kind of tape. I also used some silicon for gaskets (the red one) to be 100% sure that humidity doesn't pass.
I hope this short instructions are helpful to anyone that has the same problem as I did.
Check also the grounding before remounting it. Could also be the main problem why the switch isn't working.
