Gateron-manufactured tactile with a rounded bump and short 3.4 mm travel. Drop's in-house take on the Holy Panda lineage; available without modding, which is the whole point.
The Holy Panda was a six-month frankenswitch project for most of its life. The Drop Holy Panda X is the first version where the geometry, the spring tune, the housing pairing, and the factory lube were the spec — not the mod.
Drop Holy Panda X appears in editor-curated build sheets.
