HMX Bad Sweetheart

Linear switch switches designed by SULAB, manufactured by HMX. 

HMX Bad Sweetheart has been carefully designed to produce a deep, quiet and satisfying bottom-out experience.

The bottom housing uses a minimal amount of glass fiber in the bottom housing, a softer material for the same to achieve a quieter than usual sound profile. The top housing, bottom housing and the stem use the quietest material combination in the HMX lineup.

The ball-bottomed stem prevents a diagonal bottom-out and helps reduce slop and wobble, leading to a consistent sound and bottom out. 

The new bottom housing mold prevents the "Bulky Base" complaint of the old mold. 

Finally, each switch is lubricated from the factory with a custom formulated lubricant, giving a smooth bottom-out while maintaining a non-tacky fee.
