Product details

Designed by Rena Lab and made by HMX, the Rosa Centifolia is a factory-lubed linear built around a bright, clean clack. A strengthened LY stem meets a fibreglass-reinforced P7 bottom housing for a crisp, well-defined bottom-out, while the PA12 top keeps the keystroke smooth and lively. The sound is high-pitched and focused, and it holds its character whether your board is foamless or fully dampened.

The switch uses HMX's new L3 mould with a dedicated light guide for more even RGB shine-through. Lubing is deliberately light: a thin coat of 205g0 on the stem legs and sliders, dry-film on the spring and leaf, and everything else left dry to keep the sound clean. It comes in two weights, 45g or 53g bottom-out, with a 22mm KOS extended spring, 2.0mm pre-travel, and a short 3.5mm total travel.

Compatibility

Keyboards: fit any MX-style hot-swap board with 5-pin sockets, and can be soldered onto standard MX PCBs. On 3-pin-only boards, the two plastic side legs need clipping first.
Keycaps: standard MX cross stem, so any MX-compatible keycap set works.
Lighting: the built-in light guide is made for RGB shine-through, so it suits boards with per-key LEDs (north- or south-facing).
Not compatible with: Hall effect/magnetic boards, low-profile boards, or Alps/Topre layouts.
