It's nothing electrical. Those are levers that reach out to screws for fine adjustment of the beam alignment. One screw for horizontal and one for vertical adjustment. At first I thought I could get away with just gluing and patience, but that led nowhere. I thought for a long time and made that solution with the levers. I wonder if there is another way, but this works well.
