HMX SU Color Blue R2 Linear Switches

This linear mechanical switch is designed for users who prefer a smooth, consistent keystroke without tactile bumps or clicks. It suits typists and gamers seeking a light actuation force with a clear bottom-out feel. Factory lubrication reduces initial scratchiness, making it a good choice for those wanting a quieter, smoother typing experience without additional mods.

Feel & Sound

• Linear feel provides a smooth keypress without tactile feedback or audible clicks.
• Factory lubrication helps minimize scratchiness, contributing to a quieter sound profile.
• Bottom-out force offers a noticeable but not harsh end to each keystroke.

Actuation Characteristics

• Light actuation force supports fast, effortless key presses, reducing finger fatigue during long sessions.
• Short pre-travel distance allows for quick response, beneficial for gaming and fast typing.
• Total travel length balances responsiveness with sufficient key travel for comfortable typing.

Build Quality

• Housing made from PA12, a durable nylon material, ensures structural stability.
• Blue T5 stem offers consistent smoothness and compatibility with MX-style keycaps.
• 22mm spring length contributes to the linear force curve and bottom-out feel.
• Factory lubed spring and stem reduce break-in time and initial scratchiness.

Trade-offs

• Linear design lacks tactile feedback, which may be less satisfying for users who prefer noticeable keypress confirmation.
• Force variance of 5 cN means slight inconsistency between switches, potentially noticeable in large key sets.
• Unknown wobble and ping characteristics, which could affect feel and sound for some users.

Use Cases

• Good for gamers who want quick, smooth key presses without distractions from tactile bumps or clicks.
• Suitable for typists who prefer a quiet, light linear switch with minimal break-in.
• Less ideal for users seeking tactile or clicky feedback for typing accuracy or preference.
