Durock POM Linear

The Durock POM Linear, sometimes sold as the "Piano" switch, is a linear switch manufactured by JWK/Durock. It uses a full POM housing for both the top and bottom, a plastic known for a naturally slick, low-friction glide.

The switch pairs that housing with an extended long-pole stem, which shortens the bottom-out and gives the switch a fuller, deeper sound. Reviewers describe the stock feel as smooth and solid, with a firm, quiet bottom-out even before any hand lubing.
