HMX Rosa Centifolia Linear Switch

1 quantity = 10 switches.

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.

Customer video review of HMX Rosa Centifolia Linear Switch Factory Lubed (10PCS)

Love the pitch and volume from these switches. Went from Sunset Gleam og and was a major upgrade in sound and stability. Was deciding between Yogurt S and Rosa Centifolia but went with the strengthened LY stem and it did not disappoint.

Dry and clacky sound.

(board in video is the bachoo x osume nemui, POM plate, in top mount, with plate foam & osume tsukimi PBT keycaps) Lovely clacky switch, really enjoying the typing feel and sound. Despite having a higher pitched sound, I don't find them to be too loud and am able to work comfortably with them. I feel the video doesn't really capture the pitch of this IRL. If I had to compare the rosas to another switch, I personally think they are very close in sound to the yogurt S (which I also own), just higher pitched.

A very high pitched and clacky switch, even for HMX. Not the best for me, but still a very good switch.
