HMX SU Pink R2 Linear Switches

This linear switch offers a smooth, consistent keystroke with a relatively light actuation force, making it suitable for users who prefer effortless key presses. It fits well for gamers seeking quick response and typists who want a soft, uninterrupted typing experience. The switch is not silent, so it may be less ideal for noise-sensitive environments.

Feel & Sound

• Linear stem provides a smooth, friction-free keypress without tactile bumps or clicks.
• Moderate bottom-out force gives a noticeable end to each keystroke without harsh impact.
• Not designed for silent operation, so expect typical mechanical switch noise.

Actuation Characteristics

• Light actuation force allows for fast, low-effort key presses, reducing finger fatigue during extended use.
• Short pre-travel distance enables quick response, beneficial for gaming and fast typing.
• Total travel length provides enough depth for comfortable typing without feeling shallow.

Build Quality

• Housing made from nylon PA12 offers durability and a stable typing feel.
• T5 nylon stem reduces friction for smooth keystrokes.
• Single-stage spring design balances light actuation with consistent bottom-out force.
• Factory lubrication helps reduce initial scratchiness, improving smoothness out of the box.

Compatibility

• PCB mount with five pins ensures secure installation on compatible PCBs.
• Supports single LED lighting, suitable for keyboards with basic backlighting.
• Unknown if compatible with hot-swap sockets, so check keyboard specifications before use.

Trade-offs

• Not silent, which may be disruptive in quiet settings.
• Force variance of 3 cN means slight inconsistency between switches, potentially noticeable in large sets.
• Unknown long-term durability and response to aftermarket modifications like re-lubing or filming.
