HMX SW x Garnet Linear Switches

The HMX SW Garnet is a linear mechanical switch suited for users who prefer a smooth, consistent keypress without tactile bumps. It fits well for typists and gamers who want a moderate actuation force and a clear bottom-out feel. The switch is not silent, so it may be less ideal for quiet office environments.

Feel & Sound

• Linear design provides a smooth keystroke without tactile feedback, supporting fast, uninterrupted typing or gaming.
• Bottom-out force is slightly higher than actuation force, offering a noticeable but not harsh end to each keypress.
• Sound profile is not silent, producing moderate noise typical of linear switches without dampening features.

Actuation Characteristics

• Actuation occurs at a shallow 2.00 mm travel, allowing for quick response.
• Total travel of 4.00 mm gives a standard keypress depth, balancing speed and comfort.
• Force variance of 5 cN indicates consistent feel across keys, reducing finger fatigue during extended use.

Build Quality

• Polycarbonate top housing and nylon PA66 bottom housing combine durability with moderate sound resonance.
• POM stem reduces friction, contributing to smooth keypresses.
• 22 mm spring weighted at 50g supports a balanced resistance, neither too light nor heavy.
• Factory lubrication helps reduce initial scratchiness, improving out-of-the-box smoothness.

Compatibility

• PCB mount with 5 pins ensures stable installation on compatible boards.
• Supports single LED lighting, suitable for keyboards with basic backlighting.
• Unknown if compatible with hot-swap sockets, limiting ease of switch replacement.

Trade-offs

• Not silent, so may be less suitable for noise-sensitive environments.
• Linear feel lacks tactile feedback preferred by some typists.
• Unknown long-term durability and resistance to spring fatigue.
