They are structurally based on Kailh Hush Box Switch v3, so the specs are similar. The lifespan of Box Switch is rated up to 100 million.
Hexgears need some new types of switches to complete the aesthetics and character of our loved BoxKeyboard. Yes! BoxSwitch for BoxKeyboard, they should be born at the same time. The "Premium Silent" is the most excellent typing experience ever! The collison and the noise will be absorbed by the rubber layer, the rest is pure joy.
These switches should be looking awesome also on some other boards.
