HMX Rosa Centifolia is a factory-lubed linear switch designed by Rena Lab for a crisp, focused sound profile. Its strengthened LY stem and reinforced P7 bottom housing bring clear impact and a concentrated bottom-out, while the PA12 top housing helps preserve a lively response and smoothness without excessive harshness.
A newly molded light guide is made to better fit HMX dimensions, deliver more even RGB shine through, and support more efficient, consistent production. The result is a switch that aims for a bright, clean sound that stays composed—whether used in a foamless build or a fully dampened setup.

Factory Lubing
Stem legs and sliders receive a very thin coat of 205g0. The spring and leaf are dry-film lubed; all other areas remain dry, including the bottom housing and the area around the stem pole. This approach is intended to maintain a clean sound and reduce the chance of lubricant pooling.
