HMX Lulu Silent Linear Switches

The HMX Lulu Silent Linear is a quiet, smooth linear switch designed for users who want a firm keypress without tactile bumps or audible clicks. It suits typists and office workers needing low noise, as well as enthusiasts who prefer a solid feel with minimal stem wobble. The switch offers a subtle sound on release, adding a unique audio character without increasing overall noise.

Feel & Sound

• Provides a firm and solid keystroke, avoiding the mushy feel common in some silent linears.
• Completely silent on the downstroke, reducing typing noise in shared spaces.
• Features a small, pleasant pop sound on the upstroke (key release), creating a semi-silent, subtle thock effect.
• Low stem wobble improves stability and consistent keypress feel.

Actuation Characteristics

• Moderate actuation force supports deliberate typing without fatigue.
• Pre-travel and total travel distances are typical for linear switches, balancing responsiveness and comfort.
• Bottoming out feels firm but not harsh, aiding in typing accuracy.

Build Quality

• Top housing made of polycarbonate offers durability and clarity.
• Bottom housing uses nylon (PA66), contributing to sound dampening and structural integrity.
• Stem made from POM reduces friction for smooth keypresses.
• Factory lubed with high-quality lubricant, minimizing scratchiness and improving smoothness from the start.

Trade-offs

• The subtle upstroke pop may not suit users seeking complete silence.
• Firm feel may be less comfortable for those preferring softer or more cushioned keypresses.
• Unknown compatibility details for hot-swap or LED configurations.
