HMX Aster Linear Switch blends the best of classic design with modern refinement.
Built on the proven foundation of the HMX Cheese, Aster features the same 3.6mm LY stem produced from the original Cheese mold, along with a PA12 top housing and PA-2 bottom housing for a familiar yet signature sound profile.
Where Aster truly stands out is in its significantly improved factory lubing—carefully tuned to reduce unwanted noise while preserving a crisp, responsive typing experience.
The result? A switch that delivers a clean, clacky, and satisfyingly loud sound profile, paired with exceptional smoothness—all without any sluggish or over-lubed feel.

Factory Lubed
Yes! Stem legs and stem sliders are covered with a very thin coat of 205g0. The spring and leaf are lubed with dry film. Everything else is dry. There is no lube in the bottom housing or anywhere near the stem pole. The chance that these get lube pooling issue is very small.
