HMX Guava Linear Switches

This linear switch is suited for users who want a deep, pronounced bottom-out sound without a soft typing feel. It fits typists or gamers who prefer a firm keystroke with a heavier sound profile. The switch may appeal to those interested in unique stem materials that affect sound and feel, but less so if a cushioned or quiet experience is desired.

Feel & Sound

• The switch provides a smooth, linear keystroke without tactile bumps or clicks.
• Its stem material, high-density polyethylene (HPE), is chosen to produce a deeper bottom-out sound, resulting in a more resonant and thocky acoustic profile.
• The typing feel is firm rather than soft, so it does not cushion key presses despite the deeper sound.

Actuation Characteristics

• Operating force is moderate, requiring a noticeable but not heavy press.
• Pre-travel distance is average, allowing for responsive actuation without being overly sensitive.
• Total travel is standard, with a firm bottom-out force that contributes to the solid typing feel.

Build Quality

• Top housing is made from PA12, and bottom housing from PA66 without fiberglass, influencing the switch’s sound and durability.
• The HPE stem is uncommon and specifically selected to deepen the bottom-out sound.
• The spring is a 20mm single-stage type, supporting consistent force throughout the keypress.
• Factory lubrication uses a mix of GPL105 and GPL205 on key components, reducing initial scratchiness and improving smoothness.

Trade-offs

• The firm bottom-out feel may be less comfortable for users seeking a softer or cushioned typing experience.
• Deeper sound profile increases noise, which might be unsuitable for quiet environments.
• Unknown compatibility details and modification potential limit assessment of customization options.
