HMX Retro T Linear Switches

The HMX Retro T is a linear mechanical switch designed for users who prefer smooth keypresses with a moderate actuation force and a quieter, deeper sound. It suits typists and gamers looking for consistent, low-friction keystrokes without tactile feedback. The switch’s vintage-inspired design and full PA66 housing contribute to its distinct sound profile and durability.

Feel & Sound

• Linear and smooth keystroke with no tactile bump or click, providing consistent travel.
• Deeper, neutral sound due to the full PA66 plastic housing, reducing sharpness in key noise.
• Rounded sound profile makes it less likely to be distracting in quiet environments.

Actuation Characteristics

• Moderate actuation force around 45g, balancing between light and heavy presses.
• Pre-travel of 2.0mm offers a slightly longer distance before actuation, which some users find improves typing accuracy.
• Total travel of approximately 3.5mm with a firm bottom-out at 50g, giving a solid keypress feel.

Build Quality

• Top and bottom housings made from PA66, a durable nylon material that affects sound and stability.
• Stem made of POM, known for smooth sliding and low friction.
• Single-stage KOS spring designed for consistent force without abrupt changes.
• Factory lubed to reduce initial scratchiness and improve smoothness.

Compatibility & Mounting

• 5-pin MX-style stem compatible with most MX-compatible keycaps and PCBs.
• PCB mount design requires compatible sockets or soldering, less suited for hot-swap boards without 5-pin support.

Trade-offs

• Longer pre-travel may feel sluggish to users who prefer faster actuation.
• Linear design lacks tactile feedback, which some typists find less satisfying or prone to accidental presses.
• Deeper sound profile may not suit users seeking a quieter or more muted typing experience.
