No idea about how a resistive type is build, but I did repair a hall effect type the other day
The hall sensor is fixed in place and there are two magnets on the moving part of the throttle unit.
With throttle in closed position, one magnet is very near the throttle,
As you rotate the throttle, one magnet moves away from the hall sensor, and other get closer, and the signal ( voltage out from hall sensor ) increases.
Once the throttle is all the way open, the magnet at the opposite end of travel is almost touching the hall sensor.
I imagine a pot type throttle just has a gear on the pot and a rack on the throttle grip
