haimu SW x MP Tactile Switches

This tactile mechanical switch suits users who want a balanced typing experience with noticeable feedback and a quieter sound profile. It fits well for typists and office workers seeking consistent tactility without loud bottom-out noise. The metal-on-metal stem design offers a distinct feel and sound that may appeal to enthusiasts interested in unique switch characteristics.

Feel & Sound

• Delivers a tactile bump with moderate force, providing clear feedback without being harsh.
• Metal-on-metal contact at bottom-out creates a consistent, mixed-pitched sound that some find satisfying but may be perceived as high-pitched by others.
• Top-out sound is also distinct, contributing to an overall balanced acoustic profile.
• Quieter than many tactile switches, making it suitable for office environments.

Actuation Characteristics

• Light actuation force supports comfortable typing with less finger fatigue.
• Short pre-travel allows for responsive keypresses, aiding typing speed.
• Total travel distance is standard, providing familiar key movement.
• Bottom-out force is higher than actuation force, giving a firm finish to each keystroke.

Build Quality

• Housing made from POM, a durable plastic known for smoothness and reduced friction.
• Stem uses UPE material with a metal tip, enhancing durability and tactile consistency.
• Spring length and force tuned to balance tactility and smoothness.
• Factory lubed to reduce initial scratchiness, improving out-of-the-box feel.

Compatibility

• PCB mount design with five pins ensures stable installation on compatible boards.
• Supports SMD LEDs, allowing for backlighting customization.
• Not specified as hot-swap compatible, so may require soldering.

Trade-offs

• Metal-on-metal bottom-out sound may not suit users preferring softer or quieter feedback.
• Some builds might emphasize a higher-pitched bottom-out noise, which could be distracting.
• Unknown how it responds to additional modifications like filming or re-lubing.
