Siliworks × HMX Sonja HC Linear Switch (10‑Pack)

Brand Introduction

Designed by Siliworks - a regular hit on ThX, and meticulously manufactured by HMX, the Sonja HC (“Hardcore”) switches are crafted for purists seeking a heavier, scratch‑enhanced typing experience. These premium switches blend nostalgic inspiration with modern precision.

Product Description

The Sonja HC is a weighty linear with essentially full travel featuring a rail bottom‑out design and deliberately textured housings to evoke vintage Cherry MX feel. Only the spring and leaf components are factory‑lubed (using GPL 105/205 mix), while the housing and rails remain dry to preserve tactile feedback. With a higher bottom‑out force and more aggressive sound profile than the original Sonja, HC is built for users who value bold, character-rich typing over ultra-smooth neutrality.
