HMX XINHAI LINEAR SWITCH
The Xinhai switch distinguishes itself from other HMX switches in several notable ways. Firstly, its top housing is constructed from a softer material, PA12, as opposed to the more common PA66 or PA2. This design choice results in a less sharp and less pronounced top-out sound. Additionally, the bottom housing is composed of a modified Nylon material, a standard choice among HMX switches. Notably, the housing materials used in the Xinhai are identical to those in the HMX Macchiato; the key distinction between the two switches lies in their stem material. The Macchiato features a POK stem, lending it a pronounced 'thocky' sound in the mid-range, whereas the Xinhai employs a POM stem, producing a crisper, higher-pitched bottom-out sound.
Furthermore, Xinhai employs a unique factory lubrication technique. This method involves applying a greater amount of lubrication to the leaf spring and modifying the application process to ensure a more even distribution of lubricant.
