Comments on HMX Egg Yolk switches
The Egg Yolk is HMX's first switch with a double-shot bottom housing – and that's exactly what makes the difference in the sound profile: a deliberately engineered S1 post sits in the middle of the PA66 bottom, right where the stem hits. The result is an exceptionally clacky, crisp keypress with a surprisingly full, rounded character – substantial and defined, without letting the classic HMX clack drift into the bright or shrill range. The hardened M2 stem keeps the 3.6mm travel glassy-smooth throughout and adds a poppy snap on bottom-out. Currently considered one of the clackiest linear switches around – ideal for loud, lively builds with character – MonacoKeys.
