Sadly no they cant.

The switch thumbsticks go at a right angle to their contact point. These as you can see are a straight line.

It would make things much easier tho. But, companies gotta be all unique with their stuff and have zero interchangeability. Honestly i keep praying someone will come up with “hall effect” sticks for quest and switch.

ok. so i managed the tear down as an experiment in seeing if i could do the process without destroying anything and i had complete success! now the problem is finding a replacement for the "select, home, and start" laminate buttons on the front of my 3ds ctr-001. can anyone provide a link? google and amazon are of no help.
