HMX Saru V2 Tactile Switches

The HMX Saru V2 Tactile is a medium-light, full tactile mechanical switch suited for users who want a smooth, rounded bump with minimal pre- or post-bump travel. It fits typists who prefer tactile feedback that is close to linear in feel and enjoy a balanced, clean sound. This switch may also appeal to those who value factory lubrication for a consistent, flowing typing experience out of the box.

Feel & Sound

• Delivers a light, rounded tactile bump that is noticeable but not sharp, providing tactile feedback without interrupting flow.
• Minimal pre- and post-bump travel keeps the feel close to linear, which can suit users who want tactility without a pronounced bump.
• Produces a clacky, balanced, and clean sound that is semi-full, making it audible but not overly loud or harsh.

Actuation Characteristics

• Medium-light operating force results in less finger fatigue during extended typing sessions.
• Short pre-travel and total travel distances contribute to a responsive and quick keypress.
• Bottom-out force is slightly higher than actuation force, offering a subtle resistance before full keypress.

Build Quality

• Top housing made from PA12 nylon and bottom housing from NA2 nylon provide durability and consistent sound.
• Stem uses modified POM, which supports smooth key movement and reduces scratchiness (noise from stem friction).
• Spring is a single-stage KOS type, contributing to a consistent force curve.

Modification Potential

• Factory lubrication is applied extensively, including all stem sides, contact leaf, and housing rails, reducing initial scratchiness and leaf ping (noise from metal contact).
• Lubrication improves further with break-in, making the tactile bump more even without losing smoothness.
• Additional lubing or filming may enhance smoothness but is less necessary due to factory lube quality.

Trade-offs

• The tactile bump is light and rounded, which may be less satisfying for users seeking a strong or sharp tactile response.
• Sound is clacky rather than thocky, which may not suit quiet office environments.
• Unknown compatibility with hot-swap sockets or LED lighting effects.

Use Cases

• Well suited for typists who want tactile feedback without a harsh bump or heavy force.
• Good for users who prefer a smooth, flowing keypress with moderate sound presence.
• Less ideal for gamers needing very fast, linear switches or for office users requiring very quiet operation.
