HMX Blue Topaz Switch

The HMX Blue Topaz linear switch offers a refined typing experience with its PC top housing, LY stem, and innovative P4 bottom housing. Unlike typical PC tops, Blue Topaz’s top housing is expertly molded to minimize loose top-out noise, resulting in a more subtle and focused sound profile. The P4 bottom housing, crafted from a newly engineered nylon blend, reduces fiberglass content while incorporating PTFE into PA66, creating a tempered bottom-out feel with a quieter, softer sound. Paired with the LY stem, the Blue Topaz strikes a balance—retaining brightness without veering into deep-sounding territory. While quieter and less clacky than HMX’s Hyacinth V2, it still holds its place among vibrant and lively switches, offering a sophisticated option for enthusiasts seeking nuanced performance.
