Product details

MMD Princess Linear/Tactile switches are standard‑profile linear mechanical keyboard switches sold in packs of 10. They use a POM+PTFE stem for extra smoothness, with a modified polycarbonate (PC) top housing and nylon PA66 bottom housing to produce a deeper, crisp sound.

These switches are factory‑lubed, 5‑pin, and designed for custom mechanical keyboards where users want a medium‑weight linear feel with a shorter 3.1 mm total travel for a slightly snappier bottom‑out than typical 3.5–4.0 mm linears.
