HMX Ash Linear Switches

This linear switch suits users seeking a balanced, smooth keystroke with a clean sound that is noticeable but not loud. It fits well for typists and keyboard enthusiasts who appreciate a consistent feel and moderate resistance without tactile bumps. The switch’s design aims to reduce common issues like lube pooling, making it a practical choice for those wanting reliable factory lubrication.

Feel & Sound

• Delivers a smooth, linear keystroke with no tactile feedback, supporting fast and consistent typing.
• The POK stem creates a clean clacky sound profile that is audible yet restrained, avoiding excessive noise.
• Bottom-out feels firm but not harsh, helping prevent finger fatigue during extended use.

Actuation Characteristics

• Requires moderate force to actuate, offering a balance between light and heavy presses suitable for varied typing styles.
• Pre-travel distance allows for responsive key activation without accidental presses.
• Total travel length supports full key depression with a controlled bottom-out.

Build Quality

• Top housing made from PA12 material, chosen for smoothness and durability.
• Bottom housing uses PA66, a classic and reliable plastic that contributes to switch stability.
• Stem constructed from POK plastic, enhancing sound and smoothness consistency.
• Spring is a single-stage extended design, providing steady resistance throughout the press.

Factory Lubrication & Maintenance

• Factory lubed with a thin coat on stem legs and sliders, reducing initial scratchiness and stem wobble (side-to-side movement).
• Spring and leaf receive dry film lubrication, minimizing spring ping (vibrations from the spring).
• Lubrication is carefully applied to avoid pooling, lowering the risk of inconsistent feel or sound over time.

Trade-offs

• Linear design means no tactile feedback, which may be less satisfying for users who prefer bumps or clicks.
• Sound profile is clacky but not muted, so it might be too audible for very quiet environments.
• Unknown compatibility details with specific keyboard layouts or hot-swap sockets.
