HMX Siliworks × Sonja HC Linear Switches

The HMX Siliworks × Sonja HC Linear is a premium mechanical keyboard switch designed for enthusiasts who appreciate a heavier, more tactile linear typing experience. Drawing inspiration from vintage switch designs, it combines modern engineering with nostalgic elements to deliver a unique, character-rich feel and sound.

Design and Construction

This switch features a rail bottom-out mechanism and a full travel distance, providing a substantial and satisfying keystroke. The housing is constructed from modified PA66 with a deliberately textured finish on both the top and bottom, evoking the scratch-enhanced sensation reminiscent of classic Cherry MX switches. The stem is made from durable POM material, ensuring smooth movement and longevity.

• Rail bottom-out design for consistent feel
• Textured PA66 housing for vintage-inspired scratchiness
• POM stem for durability and smoothness

Lubrication and Components

To balance tactile feedback and smoothness, only the spring and leaf components are factory-lubed with a blend of GPL 105 and 205 lubricants. The housing and rails remain unlubricated, preserving the intended scratchy texture and enhancing the overall typing feedback.

• Springs and leaves factory-lubed (GPL 105/205 mix)
• Unlubed housing and rails for tactile bite
• 18 mm KOS single-stage spring for a firm response
