HMX Cthulhu Linear Switches

This linear switch suits users who want a precise typing experience combined with a loud, sharp sound. It fits those who prefer a clean, smooth keystroke without scratchiness and enjoy a defined, clacky acoustic profile. It is less ideal for quiet office environments or users sensitive to noise.

Feel and Sound

• Delivers a smooth keystroke with minimal friction due to a hardened POM stem, which reduces scratchiness.
• Produces a bright, sharp, and resonant clack sound, driven by a fiberglass-reinforced bottom housing that enhances acoustic clarity.
• The 22mm single-stage spring provides a consistent and solid downstroke feel, avoiding mushiness.

Actuation Characteristics

• Requires moderate force to actuate, offering a controlled typing experience without feeling too light or heavy.
• Pre-travel and total travel distances support precise keypress registration with a defined bottom-out sensation.

Build Quality

• Uses a polycarbonate top housing and a P7 bottom housing with high fiberglass content for durability and sound enhancement.
• The stem is made from strengthened POM, a harder material than standard POM, improving smoothness and longevity.
• Factory lubed to reduce initial friction and noise, which benefits out-of-the-box performance.

Trade-offs

• The loud, clacky sound may be disruptive in shared or quiet spaces.
• The firmer spring and defined feedback might feel tiring during long typing sessions for some users.
• Unknown compatibility with hot-swap sockets and LED lighting effects.
