HMX Sandstorm

These switches were produced by HMX at the request of SU LAB in China. The HMX Sandstorm switch, also going by the name HMX Dune, is one of the most impressive and aggressive tactile switches stocked on Mechstock. 

The switch is very stable, has no pre-travel, and the tactile bump is at the very top of the key-press which gives it a similar sensation to "popping bubble wrap".

Additional feedback will be noticed as you bottom-out because the HMX Sandstorm switches are long-pole and therefore have short travel. This means that center stem pole inside the switch contacts the bottom housing much quicker and harsher than a traditional MX switch. This often gives switches a more distinctive feeling and audible sound profile.

Many enthusiast like this combination of large tactility, short travel and harsh bottom-out because it adds lots of physical feeling to each press. 

The long spring used also helps keep the switch feeling responsive and snappy. Switches, like the HMX Sandstorm, that use an extended spring always return quickly on the up-stroke.

The housing tolerances are very good and tight so this switch may struggle to accept switch films. Additionally, because of the aggressive tactility, these switches are loud and audible. If you're after a cleaner sound profile, it's recommended to add dielectric grease behind the metal leaves to reduce "ping" sounds.

Pair with:

• Silicone Spring Oil
• Dielectric Grease

These switches may be fatiguing initially and can take several weeks to adjust to. This is due to the nature of tactile switches with long-poles.
