Comments on HMX Black Cat switches
The Black Cat tactile switch is a clacky-sounding long-pole tactile switch manufactured by HMX. Unlike most short travel HMX tactile switches, the Black Cat tactiles have a PA12 top housing instead of a PC one. The PA12 material is better for calming down the overall top-out sound to make it not too shrill. With the POM stem and P3 bottom housing, the Black Cat switch overall sounds very pleasant. The tactile bump is very close to a D shape, like the retro J or Hydra switches. It's rounded and very comfortable to type on – Unikeys.
