HMX
Hmx Lotus







The Lotus linear switches have a POM stem and a full nylon housing, though the nylon materials used for the top and bottom housing are fairly new to HMX. The top housing is a PA12+PA11 mix, similar to PA12 in character, creating a concentrated and subtle top-out sound. The P2 bottom housing has less fiberglass added, but still generates the signature clacky bottom-out of other HMX switches. The spring is a 22mm single-stage KOS stainless steel extended spring. Factory lubed with mixed GPL105 and GPL205 on the leaf spring, stem feet and bottom housing rails, with dry film lube on the springs.
