Overview

BSUN X is a factory-lubricated linear switch that uses POK for both housings and a modified LY material for the stem. This combination of polymers is the design’s defining feature, pairing a continuous mechanical keypress with a construction centered on low-friction surfaces. It remains a conventional contact switch, with no deliberate tactile bump or separate click mechanism.
