  I swear PS2 controllers are so old and so badly kept that it's impossible to find one for under $60 in a decent condition.
  Ended up just buying a convertor to use Series X and PS5 controllers on my PS2, since it's literally cheaper to buy a Dualsense controller than a decent Dualshock PS2 controller.

  this is from a type of old apple keyboard that came with varying switch types - some are apparently borderline mythical in quality, and others, like the ones above, are potentially among the worst switches ever made >
  
  That doesn’t look like a butterfly switch >
  
  You're right, it looks like Mitsumi standard mechanicals, which have alps mount sliders.  i dont know much about these switches, theyre probably not that bad, but definitely no amber alps >
  
  Really interesting seeing the names Alps and Mitsumi pop up here, too.
  Those are mega familiar to me from fixing up PS2 controllers. Alps, Mistumi and Hosiden were the 3 main variants of PS2 controllers, denoted by the letters A, M and H respectively on the backs of controllers (named after the factories they came from). I'm pretty sure they've been involved with playstation constrollers since the beginning. H and A variants are mega common here in UK, haven't seen a single Mitsumi PS2 controller here yet.
  Caught me off guard seeing those names  here, but I guess they make all kinds of components so not surprising.
