HMX SW x Catmint Linear Switches

This linear switch suits users who prefer a smooth, consistent keystroke without tactile bumps or clicks. It is a good choice for typists and gamers seeking a straightforward, quiet keypress with moderate actuation force. The factory lubrication reduces initial scratchiness, making it comfortable for extended typing sessions.

Feel & Sound

• Linear design provides a smooth keystroke without tactile feedback or audible clicks.
• Factory lubrication helps minimize scratchiness, resulting in a quieter, softer bottom-out sound.
• Bottoming out at 50g force offers moderate resistance, balancing speed and control.

Actuation Characteristics

• Pre-travel of 2mm means the key registers after a moderate press depth, suitable for deliberate typing.
• Total travel of 3.5mm offers a standard key travel distance, allowing familiar typing feel.
• Consistent force curve supports smooth keypresses without sudden resistance changes.

Build Quality

• Top housing made from PA12 and bottom housing from PA66 with glass fiber enhance durability and stability.
• Stem constructed from POM reduces friction, contributing to smooth key movement.
• 20mm spring length supports consistent force application throughout the keypress.

Compatibility & Mounting

• PCB mount with 5-pin design ensures secure installation and compatibility with most standard PCBs.
• Unknown LED compatibility and hot-swap friendliness.

Trade-offs

• Linear feel may be less suitable for users who prefer tactile or clicky feedback for typing accuracy.
• Moderate bottom-out force could cause finger fatigue for those who prefer lighter switches.
• Unknown long-term durability and spring noise characteristics.
