HMX Lulu Linear Switches

This linear switch suits users who want a smooth, consistent keystroke without tactile bumps or clicks. It fits typists and gamers seeking straightforward keypresses with moderate force, offering a balance between lightness and resistance. Factory lubrication reduces initial scratchiness, making it ready for use out of the box.

Feel & Sound

• Provides a smooth, linear keystroke with no tactile feedback or audible click.
• Bottom-out force adds a slight resistance near the end of the press, which some users may find helps with typing rhythm.
• Sound profile is quiet but not silent, with no built-in LED diffuser to soften keypress noise.

Actuation Characteristics

• Moderate actuation force balances responsiveness and fatigue, suitable for extended typing or gaming sessions.
• Pre-travel distance allows for deliberate keypresses without feeling overly sensitive.
• Total travel length supports full keypress depth, which some users prefer for accuracy.

Build Quality

• Top housing made of nylon (PA12) and bottom housing of N2 material provide durability and consistent performance.
• Stem constructed from modified POM, a material known for smooth sliding, reducing scratchiness.
• Single-stage spring design contributes to predictable force curve without sudden changes.
• Factory lubrication helps minimize initial stem scratchiness, improving smoothness from first use.

Compatibility

• Five-pin design supports secure PCB mounting and plate compatibility.
• Lacks an LED diffuser, which may affect RGB lighting diffusion if that is a priority.

Trade-offs

• No LED diffuser means lighting effects may be less uniform or bright compared to switches with built-in diffusers.
• Factory lube quality is generally good but may still benefit from additional lubing or filming for enthusiasts seeking ultra-smooth feel.
• Unknown details on long-term spring noise or stem wobble, so some break-in period may be necessary.
