HMX Lotus Linear Switch Factory Lubed Edition

HMX Lotus Switches

Refined sound with a smoother edge.

HMX Lotus switches are linear switches designed by Udon, built around a POM stem and a full nylon housing to deliver a balanced, controlled sound profile. The updated top housing (PA12 + PA11 blend) helps keep the top-out subtle and focused, while the P2 nylon bottom housing maintains that signature HMX clacky bottom-out—just slightly more refined.

The result is a switch that keeps the character HMX is known for, but smooths out the edges for a cleaner overall experience.

What you’ll notice:

• Smooth linear travel with consistent feel
• Controlled top-out with a refined sound profile
• Light, clacky bottom-out without being overly sharp
• Balanced acoustics across the full keystroke
