HMX Cola Linear Switches

This linear switch is suited for users who prefer a smooth keystroke with a longer travel distance and a distinct clacky sound. It fits typists or gamers who want a consistent, non-tactile feel combined with audible feedback that is not sharp or dry. The extended travel and moderate actuation force make it a choice for those who value a noticeable keypress without tactile bumps.

Feel & Sound

• Provides a smooth, linear keystroke without tactile feedback, suitable for users who prefer uninterrupted key travel.
• Produces a clacky sound with a lively tone, due to its PA66 fiberglass housing and L2 mold, which avoids a flat or muted noise.
• Longer total travel (3.8mm) offers a more deliberate keypress compared to shorter linear switches, affecting typing rhythm and feedback.

Actuation Characteristics

• Requires moderate force (45g) to actuate, balancing between light and heavy keypresses for controlled input.
• Pre-travel of 2.0mm means the key registers input after a noticeable initial movement, which may suit users who prefer clear actuation points.
• Bottom-out force is slightly higher (52g), providing a firm end to the keypress that can reduce accidental presses but may increase finger fatigue over long sessions.

Build Quality

• Housing made from PA66 with fiberglass reinforcement enhances durability and contributes to the switch’s distinct sound profile.
• Stem is made of POM, a material known for smooth sliding, which supports the linear feel.
• Includes a 22mm single-stage spring designed for consistent resistance throughout the keypress.
• Factory lubed with a thin coat on stem legs and sliders, plus dry film lubrication on spring and leaf, reducing initial scratchiness and noise.

Trade-offs

• Longer travel distance may slow down rapid keypresses, making it less ideal for users seeking very fast actuation.
• Clacky sound is louder than silent linear switches, which might be distracting in quiet environments.
• Moderate bottom-out force can cause finger fatigue during extended typing sessions for some users.
