Product Description

This linear switch targets users who want a smooth, consistent keystroke with medium actuation force and care about the materials affecting feel and sound. It suits typists or gamers preferring a quieter, non-clicky experience with a longer stem for a distinct typing sensation. The switch is less ideal if you want tactile feedback or factory lubrication.

Feel & Sound

  • Provides a smooth, linear keystroke without tactile bumps or clicks.
  • The longer stem design offers a unique typing feel compared to standard switches.
  • Material choices, including HDPE and nylon, influence a balanced sound profile, reducing harshness and emphasizing a softer thock.

Actuation Characteristics

  • Medium actuation force around 55 g supports deliberate keypresses without excessive effort.
  • Total travel of approximately 3.5 mm allows for full key travel with a defined bottom-out feel.
  • Long stem length may slightly affect keypress timing and feel compared to shorter stems.

Build Quality

  • Top housing and stem made from HDPE, a dense plastic that can improve sound and durability.
  • Bottom housing uses nylon, contributing to the switch’s acoustic and tactile characteristics.
  • Spring is standard linear type, providing consistent resistance throughout the press.

Modification Potential

  • Comes unlubricated, so users seeking smoother or quieter operation should plan to apply lubrication.
  • Long-pole stem design may respond differently to filming or lubing compared to standard stems.

Trade-offs

  • No factory lubrication means initial scratchiness or noise may be present until broken in or lubed.
  • Long stem length could increase stem wobble, affecting stability for some users.
  • Lacks tactile or audible feedback, which may not satisfy users who prefer more pronounced keypress sensations.
