Comments on HMX TT Red switches
The HMX TT Red switches are manufactured using HMX's new mold set. If you are looking for another clacky HMX switch, you have come to the right place. The new molding design makes them sound clacky, high-pitched, and full at the same time. The PA12 top housing and POM stem ensure its smoothness and a quieter top-out sound. Unlike most HMX switches, which use nylon bottom housing with fiberglass, TT Red has a pure PA66 bottom housing instead. It might make them slightly less clacky and loud, but it helps the switch to sound less thin – Unikeys.
