Not heard of the Forced Switch Button, the only reference to switch button in the manual describes it as the following Switch Button - internal name for your reference only. Appears on the layout area.
if you use advanced moves to switch character behavior and then use a collision based advanced to change behavior, it doesn't change the switch so now you can force the switch to change so that gameplay stays correct this was used to make the bumpers in GLTCH https://www.buildbox.com/make-your-own-game/
