So these come in either white Omron switches or Topre...this should be easy if you can press a key
Is there any audible/tactile feedback? If not, omrons
Is there a deep thocking sound? Topre
This might apply, but this looks like the Topre version because of the side-printed legends on the blue keys on the home row - something that appears to be absent in the Alps versions. I say this without full confidence.
