Hmx Blue Topaz

The HMX Blue Topaz linear switch has a PC top housing, LY stem, and P4 bottom housing. The top housing is specially molded to eliminate loose top-out sound, giving a subtle, concentrated tone. The P4 bottom housing is a new nylon blend (less fiberglass, more PTFE added to PA66) that sounds quieter and tempers the bottom-out feel compared to P3 or PA3.0 housings. Paired with the LY stem, it is not a deep-sounding switch, and is quieter than HMX options like Hyacinth V2, though still in the same general category.
