Ktt Hyacinth Linear Switches

The KTT Hyacinth Linear is a smooth, linear mechanical switch designed for users who prefer a shorter travel distance and a softer bottom-out feel. It suits typists and gamers looking for a light actuation force with minimal tactile feedback. This switch is not silent, so it may be less ideal for quiet office environments.

Feel & Sound

• Linear design provides a smooth keystroke without tactile bumps or clicks.
• Shorter pre-travel of 1.9mm allows for quicker key registration compared to standard switches.
• Softer bottom-out due to a long pole POM stem reduces finger fatigue during extended typing.
• Not silent, so key noise is noticeable but typical for linear switches without dampening.

Actuation Characteristics

• Actuation force of 45g offers a light touch suitable for fast typing or gaming.
• Bottom-out force of 56g provides a gentle resistance at the end of the keypress.
• Total travel of 3.5mm is slightly shorter than many standard switches, contributing to a quicker response.

Build Quality

• Polycarbonate top housing and PA66 bottom housing balance durability and sound profile.
• POM stem material reduces friction for smoother keypresses and less stem wobble.
• 22mm single-stage spring supports consistent force throughout the keystroke.
• Factory lubed, which can reduce initial scratchiness and improve smoothness.

Compatibility

• PCB mount with 5 pins ensures stable installation on compatible boards.
• Supports single LED lighting, suitable for keyboards with basic backlighting.
• Hot-swap compatibility is unknown.

Trade-offs

• Not silent, so it may not be suitable for noise-sensitive environments.
• Force variance of 5cN means slight inconsistency between switches is possible.
• Unknown how well it responds to additional modifications like filming or re-lubing.
