Product Description

This linear switch suits users who want a smooth, quiet keypress without tactile feedback or clicking noise. It fits well for both focused typing and gaming where consistent, fast actuation and low sound are priorities. The switch offers a controlled feel with minimal distractions, making it a practical choice for office or home setups emphasizing quiet operation.

Feel & Sound

  • Provides a smooth keystroke with no tactile bump or audible click, resulting in a quiet typing experience.
  • Reduced noise on bottom-out helps minimize distractions in shared or quiet environments.
  • Lacks tactile feedback, which may feel less engaging for users who prefer a noticeable actuation point.

Actuation Characteristics

  • Moderate actuation force supports comfortable typing without excessive finger fatigue.
  • Pre-travel and total travel distances balance responsiveness with deliberate keypresses.
  • Consistent linear force curve enables predictable key behavior, beneficial for fast-paced input.

Build Quality

  • Top housing made of transparent polycarbonate enhances durability and allows RGB lighting diffusion.
  • Bottom housing uses nylon for structural stability.
  • Stem material is POM (polyoxymethylene), chosen for low friction and precise movement.
  • Factory lubrication reduces initial scratchiness, improving smoothness out of the box.

Compatibility

  • Standard 5-pin MX-style mount fits most PCBs and supports plate mounting.
  • Compatible with common hot-swap keyboards and RGB lighting setups.

Trade-offs

  • Linear design means no tactile or auditory feedback, which some users may find less satisfying.
  • Unknown long-term durability and potential for stem wobble or spring noise.
  • Factory lube quality is adequate but may benefit from additional lubrication or filming for further smoothness and sound dampening.

Use Cases

  • Well suited for office environments or shared spaces where quiet operation is important.
  • Good choice for gamers who need fast, consistent keypresses without distractions.
  • Less ideal for typists who prefer tactile or clicky feedback to confirm key activation.
