Switch Overview

The Bad Sweetheart, designed by Rena Lab, is one of the deepest-sounding HMX switches so far. Its T5 UPE-blend stem, spherical stem tip, and new P4 bottom housing molding give it an atypical HMX sound. The P4 bottom housing uses minimal fiberglass to eliminate a clacky tone, making this a good option for fans of deep, thocky, unmuted switches. It is factory lubed with mixed GPL105 and GPL205 on the leaf spring, stem feet, and bottom housing rails.
