Time to pull the pin on this crank.
Out it comes. There's a cylindrical magnet embedded in the shaft. As it cranks, the rotating magnetic field hits the aforementioned Hall-effect sensor, which activates ... something, in your game.
One thing this crank won't do? Drift. There's no wiper or spring or sensor surface to wear out. The design is simplicity itself. You might even say there's ... no cranky-panky.
The Hall-effect sensor used here is an Infineon TLV493D-A1B6.
Elsewhere on the front side, the tiny mono speaker is adhered in place. Pretty easy to remove, but would be fussy to rework and replace.
