Crystal Iceberg switches, exclusively from Upgrade Keyboards and manufactured by Aflion. These switches have a very unique sound profile that is unlike most other switches - giving it a crisp tone that is right in the middle of the traditional "clack" vs. "thock" - Take a listen below to a sound test showcasing both stock, and lubed sounds from the switch.REMINDER: These are 2 stage springs, which means they will feel slightly heavier than they are rated in real world usage. If you typically like a standard 65-67g spring, we would recommend the 63g - etc.
The Crystal Iceberg is a linear switch that has a silky smooth travel, and constant pressure from top to bottom thanks to its 2 stage spring design.
