Bsun Aniya Linear Switches

The BSUN Aniya Linear switch is a smooth, linear mechanical switch suited for users who prioritize a consistent, quiet keystroke with a deep sound profile. It fits well for typists, coders, and gamers who want a buttery-smooth keypress without tactile bumps or clicks. Its factory lubrication and low-friction materials aim to deliver a refined feel right out of the box.

Feel & Sound

• Linear action provides a smooth, uninterrupted keystroke without tactile feedback.
• The full POM housing reduces friction, contributing to a soft, "thocky" sound with a deep bottom-out tone.
• Suitable for users who prefer a quieter but sonorous typing experience rather than sharp clicks or clacks.

Actuation Characteristics

• Light actuation force around 42g allows for responsive keypresses with moderate effort.
• Pre-travel of 2.0mm and total travel of 3.2mm provide a balanced key travel distance common in many mechanical switches.
• Bottom-out force of 50g offers a noticeable but not harsh end to each keystroke.

Build Quality

• Stem made from LY material, chosen for low friction and smooth movement.
• Top and bottom housings are POM (Polyoxymethylene), which helps reduce scratchiness and enhances sound quality.
• Uses a 20mm single-stage extended spring for consistent force throughout the press.
• Factory lubrication includes Krytox 205g0 and 105 on sliders and dry film lube on stem sliders and spring, improving smoothness and durability.

Trade-offs

• Linear design lacks tactile feedback, which may be less suitable for users who prefer noticeable actuation points.
• While factory lubed, additional lubing or filming could further reduce any minor stem wobble or noise, but this is unknown.
• Unknown compatibility with hot-swap sockets or LED lighting due to lack of specific data.

Use Cases

• Good for typing and coding where smooth, consistent keystrokes reduce finger fatigue.
• Suitable for gaming due to light actuation and smooth travel, allowing quick key presses.
• Less ideal for users seeking tactile or clicky feedback or extremely quiet switches for noise-sensitive environments.
