Switch Overview

The HMX Longjing S tactile switch is the successor to the Gateron Longjing tactile switches. The two do not differ much in materials, but HMX's light tactile molds make them feel and sound drastically different. Longjing S is similar to the HMX K01 tactile switch, delivering a mid-clacky bottom-out sound, and its tactile bump is on the smaller side, close in size to Cherry Brown. Factory lubed: a very thin coat of 205g0 on the stem legs and sliders, with the spring and leaf lubed with dry film; everything else is dry, with no lube in the bottom housing or near the stem pole.
