HMX Saru V2 Tactile Switches

This tactile mechanical switch suits users who want a light to medium actuation force with a clear tactile bump that remains noticeable without feeling heavy. It fits typists seeking a tactile experience that approaches linear smoothness after break-in. The switch produces a balanced, somewhat clacky sound, making it less ideal for quiet office environments but suitable for those who prefer audible feedback.

Feel & Sound

• Delivers a medium-light tactile bump that feels full but not sharp, providing clear feedback without harshness.
• After a break-in period, the factory-applied lube spreads evenly, softening the bump and making the feel closer to a light tactile or linear switch.
• Sound profile is clacky and balanced with a clean, semi-full tone, which may be noticeable in quiet settings.

Actuation Characteristics

• Actuation force is moderate, requiring about 48g, which balances responsiveness and fatigue reduction.
• Pre-travel and total travel distances are typical for tactile switches, supporting precise keypress registration.
• Bottoming out feels consistent with a slightly heavier force, helping prevent accidental double presses.

Build Quality

• Top housing made from PA12 nylon and bottom housing from NA2 nylon provide durability and moderate sound dampening.
• Stem is modified POM, contributing to smooth keypresses and reduced friction.
• Spring is a single 20mm KOS type, tuned for medium-light resistance.
• Lubrication is applied on all critical contact points, reducing scratchiness and leaf ping (spring noise).

Compatibility & Mounting

• Features a 5-pin MX-style PCB mount, compatible with most standard mechanical keyboard PCBs.
• Unknown if compatible with hot-swap sockets or specific LED types.

Trade-offs

• Requires a break-in period for lubrication to fully settle and optimize feel.
• Sound may be too clacky for users needing quiet operation.
• Less tactile sharpness may be a downside for those preferring a more pronounced bump.

Use Cases

• Good for typists who want tactile feedback without heavy force or sharp bumps.
• Suitable for users who appreciate a slightly audible typing sound and balanced key feel.
• Less ideal for office environments requiring silent switches or for gamers needing ultra-fast linear response.
