Oh I get it...
Microswitch stick = The Joystick's Microswitch.

Could you do the same efjayel switch hack to the switches in a joystick?
Yeah, I did it to a Happs Super Joystick. It was so clicky and annoying. Now it makes no noise. Well its not completely silent but any noise you hear are the other mechanical parts in the joystick. Feel a lot smoother too. Doing 360's on it is a joy.
