spotted this in my office the other day, tucked away in the back corner of a meeting room. sorry for the bad lighting/photo quality.
based on info online I think these are hall effect switches. I may be wrong though.
the cabinet. a mixture of high, spherical caps, and flat relegendable caps.
closer shot. note that the alpha keys are in a 5x5 array..
the switches! very long, smooth linear travel. feel really nice.
