Manufacturer description
The GravaStar Mercury K1 brings a 75% layout and an aluminum alloy exoskeleton with a gradient black finish to a desk that needs to look as sharp as it performs. Inside, custom GravaStar x Kailh linear switches run a 40gf actuation force with 1.5mm pre-travel and 3.5mm total travel, so keypresses register fast in-game without the accidental taps a heavier, longer-throw switch invites. The gasket-mounted structure pairs a flexible polycarbonate plate with five layers of sound-dampening foam, softening each keystroke and cutting the hollow rattle that makes long typing sessions grating…
