HMX Black Cat Tactile Switches

The HMX Black Cat Tactile is a full tactile mechanical switch suited for users who want clear tactile feedback with minimal linear travel before and after the bump. It fits typists who prefer a pronounced tactile sensation and a bright, high-pitched sound profile. It may also appeal to those looking for a switch with a distinct clacky and resonant acoustic character rather than a muted or thocky sound.

Feel & Sound

• Provides a strong tactile bump with minimal linear travel before and after, offering precise feedback without excessive travel distance.
• Produces a bright, high-pitched, and clacky sound, which may be noticeable in quiet environments or shared workspaces.
• The modified PA12 top housing contributes to the switch’s resonant and sharp acoustic profile.

Actuation Characteristics

• Actuation force is moderate, requiring about 35g, which balances responsiveness and deliberate keypresses.
• Pre-travel is around 2.5mm, allowing for a tactile bump early in the keypress.
• Total travel is approximately 3.0mm, typical for most mechanical switches, with a firm bottom-out feel due to the spring design.

Build Quality

• Top housing is made from modified PA12, enhancing sound brightness and durability.
• Bottom housing uses P3 nylon with 30% fiberglass, providing structural stability.
• Stem is hardened POM, a material known for smoothness and wear resistance.
• Spring is a single-stage 22mm KOS type, contributing to consistent force throughout the keypress.
• Factory lubed with a mix of 205G0 and 105 lubricants on key contact points, reducing scratchiness and noise.

Trade-offs

• The bright and clacky sound may be disruptive in quiet settings or open offices.
• Minimal linear travel around the tactile bump means less smoothness for users who prefer gradual force curves.
• Unknown compatibility details may require verification for specific keyboard builds.

Use Cases

• Well suited for typists who want clear tactile feedback and audible keypress confirmation.
• Less ideal for office environments requiring quiet operation or for gamers seeking rapid, smooth keypresses.
• Good for users who appreciate a distinctive and bright sound signature in their typing experience.
