HMX Sandstorm

HMX Sandstorm – Tactile Switches with a Pronounced Bump and Crisp Sound

The HMX Sandstorm, manufactured by HMX, redefines the tactile experience through a combination of a precise bump and a signature clacky sound. Inspired by the Type R structure, Sandstorm delivers a distinct tactile feel from start to finish, with a nearly imperceptible short linear portion at the end of the press.

Unique Tactile Experience

Sandstorm features a profile close to a "D tactile" type, where each press begins and ends with clear, consistent feedback.
The tactility is constant, delivering a satisfying, rhythmic feel during typing — ideal for those who prefer a well-defined response without compromising the fluidity of movement.

Innovative Construction & Distinct Acoustics

Upper Housing: Polycarbonate (PC) – HMX's new top housing design with a wider upper opening eliminates the syringe effect and provides smooth, controlled movement.
Lower Housing: PA66 (Nylon) – delivers structural stability and a full, balanced sound.
Stem: POM – ensures solid tactile feel and fast key return.

Acoustically, Sandstorm preserves the signature HMX sound: a clacky, crisp, satisfying tone that accentuates each press.

High-Precision Factory Lubrication

Each switch is factory-lubed with a thin film of Krytox 205g0 applied to the stem legs and rails.
The spring and metal contact are also lubed to ensure consistency and a smooth feel in use.
