HMX Lunar Stone Linear Switches

The HMX Lunar Stone Linear is a smooth linear switch designed for users who prefer a consistent keystroke without tactile bumps or clicks. It suits typists and gamers seeking a fuller, thockier sound with a bassy bottom-out. Its unique full POM housing offers a distinct feel and sound compared to other HMX switches. This switch is a good choice if you want a smooth travel with a subtle audible scratch typical of full POM materials.

Feel & Sound

• Provides a very smooth keystroke with no tactile feedback, ideal for linear switch fans.
• Produces a fuller, thockier sound with a bassy bottom-out, which some users find satisfying.
• Includes an audible scratch sound from the POM housing, a characteristic some enthusiasts appreciate but may be distracting to others.

Actuation Characteristics

• Requires moderate force to actuate, balancing responsiveness and fatigue.
• Pre-travel and total travel lengths support a smooth, controlled keypress suitable for both typing and gaming.
• Bottom-out force is slightly higher, providing a firm end to each keypress without harshness.

Build Quality

• Features a full POM housing and stem, which affects sound and smoothness differently than common plastic housings.
• Uses a KOS single-stage extended spring, contributing to consistent force throughout travel.
• Factory lubed with a thin coat on stem legs and sliders, plus dry film on spring and leaf, reducing lube pooling issues and improving smoothness.

Trade-offs

• The audible scratch from the POM housing may not suit users seeking a quieter or smoother sound profile.
• Full POM construction can produce a unique sound that may not blend well in all keyboard builds.
• Unknown compatibility details such as hot-swap friendliness or LED support.
