HMX Bad Sweetheart Linear (10 pack)

Manufacturer Introduction:
HMX, a leading name in the switch community, collaborated with Rena Labs (one of our closest partners in the industry) to create their deepest-sounding linear yet. Drawing on advanced materials and design refinements, this switch marks a bold step for HMX's enthusiast lineup. 

Product Description:
The Bad Sweetheart delivers a rich, deep acoustic tone with a firm yet smooth push feel—far from muted or shrouded. The T5 spherical UPE stem, combined with a PA12 top housing and new P4 bottom housing (with minimal fiberglass), gives each keypress a satisfying thock and a solid bottom-out echo, without unwanted clack. The tight-precision molds and factory-lubed leaf, spring, stem, and bottom rails ensure excellent glide and minimal friction. This switch stands out if you're after depth and presence, not just silence.
