Ttc Uranus HE Linear Switches

The Ttc Uranus Magnetic HE Linear is a smooth, quiet linear switch with Hall-Effect magnetic actuation. It suits users who want consistent, low-fatigue typing or extended use without debounce issues. Its muted sound and gentle feel make it a good choice for office environments or shared spaces. It requires a compatible Hall-effect PCB and is less suited for those seeking tactile feedback or a clicky experience.

Feel and Sound

• Delivers a light, consistent keystroke with a 32 g actuation force, reducing finger fatigue during long sessions.
• Linear and smooth, with no tactile bump or click, supporting fluid typing or gaming.
• Soft elastic buffers reduce bottom-out noise, producing a muted pop quieter than typical Hall switches, suitable for quiet environments.

Actuation Characteristics

• Magnetic Hall-Effect actuation provides contactless key registration, eliminating debounce delay and switch wear.
• Adjustable pre-travel from 0.1 to 3.5 mm allows customization of trigger point on compatible PCBs.
• Total travel of 3.5 mm offers a standard keypress depth, balancing speed and feedback.

Build Quality

• POM housing and boxed POM stem reduce stem wobble, improving typing stability and dust resistance.
• Factory self-lubricated with POM materials, minimizing initial scratchiness and maintenance needs.
• Extended stainless steel spring supports durability and consistent force over time.
• Rated for 100 million keystrokes, indicating long lifespan.

Compatibility and Limitations

• Requires 5-pin Hall-compatible PCBs, limiting use to specific keyboards.
• Not hot-swap compatible with standard PCBs without Hall-effect support.
• Lacks tactile or clicky feedback, less ideal for users who prefer pronounced key response.
• Sound profile is quieter but includes a soft pop, which may still be noticeable in very quiet settings.
