Do you have retail home security stores where you live ? Or DIY type home improvement stores.. You might be looking too deeply into this when what you could use is close by you.. and not too expensiveI'm not saying any of these companies/stores are available to you, but these are the types of magnetic switches I think might work for your application.In the first one, I'm looking at switches like AWS-21 that would require a small round hole to be drilled for mounting. Many could be done around the movement of the handle axle point. With just one magnet mounted to the handle part.Look for normally OPEN type of course..http://www.alstron.com.sg/security_magnetic_switches_1.htmhttp://www.radioshack.com/product.asp?cata...uct%5Fid=49-496http://www.hometech.com/security/acc.html

I saw this site long ago... which inspired me to do the same...http://forums.avsim.net/user_files/108029.jpg

I had a similar setup. Problem is that I don't feel this solution isn't reliable enough and does not work fine with the F50 and other types that have flaps levers that don't move in a straight line.That's why I am looking for another solution. With these reed sensors there is no physical contact required which should be much better. I've sent an e-mail explaining the situation of the application and asked 'meder' which one of their products would sute best.

Actually, Brass does corrode... and quite rapidly. Anodized brass might work better.

In case anyone is still interested in this topic, I have described my solution to the flaps 'problem' (using a slide potentiometer) in a post in the FDS forum. Here are a couple of pictures of my solution for the 737 flaps. The link to my post at FDS (& more pictures) is:http://www.flightdecksolutions.com/forum/v...opic.php?t=1857Flaps 0 PositionFlaps 40 Position.The calibration of the flap position was quite easy with the 8/8/8 Phidgets interface card.
