HMX Siliworks X Sonja Linear Switches

The HMX Sillyworks X SONJA LINEAR is a linear mechanical switch designed for users who prefer a smooth keypress with a distinct scratchy texture. It suits typists or gamers looking for a bottom-out switch with a unique tactile surface feel rather than tactile feedback. The switch offers moderate actuation force and a consistent travel distance, making it suitable for those who want a balance between lightness and control.

Feel & Sound

• The switch provides a smooth linear keystroke without tactile bumps, focusing on consistent downward motion.
• The top housing features a rough texture that creates a subtle scratchy sensation during keypresses, adding a unique tactile layer to the otherwise smooth feel.
• Sound profile is influenced by the rail bottom-out design, producing a moderate bottom-out noise with no additional dampening.

Actuation Characteristics

• Requires a moderate operating force around 45g, offering a balance between light and firm keypresses.
• Pre-travel of 2.0mm and total travel near 3.9mm provide a standard mechanical switch distance, suitable for both typing and gaming.
• Bottom-out force is slightly higher than actuation force, giving a defined end-point without harsh impact.

Build Quality & Lubrication

• Constructed with PA66 housings and a POM stem, materials known for durability and smooth sliding.
• Factory lubed on leaves and springs using a mix of GPL105 and GPL205, reducing initial scratchiness and leaf ping (spring noise).
• Stem and housing rails remain dry, preserving the intended scratchy texture but potentially increasing stem noise or requiring break-in.

Trade-offs

• The intentional rough texture adds a scratchy feel that may not suit users seeking a completely smooth switch.
• Dry stem and housing can result in higher stem noise or longer break-in time compared to fully lubed switches.
• Bottom-out rail design can produce a sharper sound and feel at the end of travel, which may be distracting in quiet environments.
