Comments on HMX Cosmic Purple switches
The HMX Cosmic Purple linear switches are manufactured using HMX's brand new full POM housing mold. It is the first HMX switch that comes with a full POM housing. Full POM housing with LY stem is not rare to see in this hobby but HMX makes it distinct; Most POM housing and Ly stem switches, such as BSUN Aniya and BSUN Dusty Rose, are deep and thocky sounding. That's not the case with Cosmic Purple; Thanks to HMX's molding design and unique LY blend, Cosmic Purple switches are super clacky and higher pitched. The POM housing widens the sound spectrum and makes them sound full and vibrant at the same time. We also left a bit of audible scratch to these switches if that's what you like – Unikeys.
