3D Controller Trigger Not Working

[linkt101]

I was playing with my 3D controller when suddenly the R-Trigger no longer worked. I opened up the controller and couldn't see anything wrong with it when directly compared to the fully functional L-Trigger. I gave the controller a general clean anyway, but the problem still persists. Does anyone have advice for what steps I should follow for getting the trigger to work again?

EDIT: One thing I did notice when I first opened up the controller was there was a loose plastic disc inside the controller. Something that could be easily heard when shaking the controller before I opened it up.

EDIT_2: OK, it appears to be a small magnet, but no idea where it's supposed to go.

Yay, managed to get it working. Removing the trigger was tricky and hurt my fingers trying to bend the various bits of plastic that keep the trigger in place. Not to mention it requires excessive force. Thus hurts my fingers trying to pry and hold them open. You also have to insert the magnet a certain way, which I was fortunate enough to get right first time. Also, putting the controller back together again was as difficult an experience as the GameCube controller was, but here's where you need to insert the magnet.

Hmm. very interesting. Wonder what the purpose of that disc is.

Happy to hear you got it fixed though

Most controllers use potentiometers. I'm guessing this one can determine inputs based off the strength of magnetic fields. One advantage I could think for this, is that it will make the controller less prone to wear and tear,

If your correct thats pretty cool. My knowledge on all these sort of things is extremely limited but I love seeing how tech develops over time.
