Hmx Rain Rail Bottom-out





The HMX Rain Rail Bottom-Out is a five-pin linear switch with a scratchy feel throughout, pairing a rail bottom-out structure with materials chosen to keep the keypress relaxed and consistent. Matte guide rails and updated stem-mold components create a uniform sandy texture; the PA66-with-fiberglass housing was chosen for stability, and the POM-blend stem for its textured feel. It is effectively the rail-bottom-out version of the HMX Azalea linear switch. Factory lubrication is tuned for scratchy switches: a thin dry-film on spring and stem, with the leaf and bottom-housing spring-contact area evenly lubricated to control metallic noise, while unnecessary areas are kept dry.
