Gateron Harmonic Clicky

Gateron Harmonic Clicky is a dual-rail clicky switch from Gateron's Custom Switches Series, built around a redesigned click leaf meant to give consistent click timing and sound across keys. Reviewers describe a firm, pronounced click paired with a clear tactile bump, with some scratchiness on the upstroke rather than a fully clean return.

It ships factory lubed and is usable without further modification, though the click mechanism is sensitive to over-lubing.
