It relies on a little roll pin pressed perpendicularly into the rotating shaft of the switch, which aligns with a slot in the end of the shift shaft. When the switch is installed at the factory, it must be aligned by eye before bolting it in place. It is easy to get it miss-aligned, which could bend or break the roll pin.
The switch is underneath the sprocket cover.
That's good news, an easy fix. The little roll pin fell to the bottom of the case somewhere, and surrounded by the relatively thick oil, will live its life stuck like glue in a little crevice, out of the way. It won't move when you hit a bunch of bumps, won't get into the oil system, and can't get into the gears.
