Gateron produces what is arguably the best Cherry MX clone switch out of China to date. Many users even prefer them to genuine Cherry switches because of the extreme smoothness they exhibit even without lubrication. Their smooth action can likely be attributed to a softer stem material and high quality copper click leafs.
Gateron MX-mount switches use the same cross-shaped stem so they should be compatible with all the same keycaps that fit Cherry MX switches. They use a identical color coding categorization system based on stem color (with similar feel and characteristics of the same color Cherry counterpart), though switch variety is more limited. Gateron switches are easily identifiable by their clear casing and “Gateron” branding.
