HMX
Hmx Tt Red







The HMX TT Red uses HMX's new mold set, whose design makes it sound clacky, high-pitched, and full at once. The PA12 top housing and POM stem ensure smoothness and a quieter top-out. Unlike most HMX switches, which use nylon bottom housing with fiberglass, TT Red has a pure PA66 bottom housing: slightly less clacky and loud, but it keeps the switch from sounding thin. Factory lubed with mixed GPL105 and GPL205.
