The stick has two rotating switches that contain circular resistant (I think). I detached the malfunctioning switch with a soldering iron and opened it. There was a small piece of metal conductor with a poped out head and 2 hands. I raised the head and the hands a little and cleaned the resistant layer. After closing and reattaching the switch, It was working fine.
