HMX Crisp

Quick Summary

The HMX Crisp is a light POM linear engineered for sound. By mixing Teflon powder into the housings, HMX concentrates the acoustics into a clean, high-pitched, clacky signature that lives up to the name. It’s smooth stock thanks to the naturally slick PTFE-infused POM, and it comes in both 37g and 42g weights. If you want a poppy, bright linear that’s easy on the fingers, this is a strong budget option.

Specs and Feel

Crisp is offered in a 37g version (43g bottom-out) and a 42g version (48g bottom-out), both with a 2.0mm pre-travel and a short 3.5mm total travel that keeps the press quick. The construction is the story: a POM stem in a PA12+PTFE top housing and a POM+PTFE bottom. Teflon in the housing does two things: it lowers friction for a slick stroke, and it tightens the sound into a clearer, more focused clack. The POM stem and bottom housing add the bright, distinct top-end that gives it the high-pitched crisp character. The 22mm KOS single-stage spring keeps the return brisk. Stock smoothness is good and there’s essentially no scratch; wobble is controlled.

Tuning

The PTFE-infused POM is already slick, so these are genuinely good stock and don’t need lube to feel smooth. If you want to preserve the bright, crisp sound, leave them dry-ish. Heavy hand-lube will mute exactly the high-frequency clack you bought them for. A spring swap to dial in weight is the only worthwhile mod. Films are unnecessary.

Verdict

Buy the Crisp if you want a clean, high-pitched, clacky linear with low effort and a slick stock feel. It’s brighter and poppier than HMX’s all-Nylon switches like the Hibiscus 42g, which sound deeper and rounder by comparison. If you like a sharp, articulate keystroke and a light press, the Crisp delivers. Just skip it if you’re chasing a deep, muted thock.
