Overview

The Gateron UHMknown is a linear switch built around a UHMWPE stem paired with a nylon top housing and an INK bottom housing. Its defining feature is a stem mold made specifically for UHMWPE, introduced to give the material more consistent tolerances than earlier Gateron stems produced in molds intended for other plastics. Shipped factory lubed, it is generally described as moderately smooth with a soft, mid-range stock sound.
