HMX X 80 RETROS KD400 Linear Switch Factory Lubed (35PCS)

These are great. I’ve used so many hmx switches and so far these are my favorite. I have replaced my Geon F1’s and Glare65’s switches with these switches and they sound flawless and the factory lubing is consistent and well done. The kd200 and hmx retro t’s I had before in these boards were also great, but these kd400 are even better.

Awesome switches. I can only compare them to the Xinhai and Oil Kings, and I think HMX has once again brought us a killer switch. The KD400 feel super smooth and have a very crisp sound. They're also a little louder compared to the Xinhai, but I wouldn't expect a huge difference. All in all very well recommended.

Super Clacky, I have the 63g bottom out version and they are very nice to type on, probably my favourite heavy linear for 2026 so far 😀
