Mercury K1 75% Wireless Mechanical Gaming Keyboard

The GravaStar Mercury K1 is a 75% wireless mechanical gaming keyboard built around an aluminum alloy exoskeleton. It ships with custom GravaStar x Kailh Cheery Pink linear switches factory-lubed for a 40 gf actuation force, 1.5 mm pre-travel and 3.5 mm total travel. The compact 79-key layout plus a programmable control knob targets gamers and typists who want a smaller footprint without losing dedicated function rows.

Aluminum Exoskeleton Gasket Mount

A streamlined aluminum frame measuring 343 by 156 by 46 mm and weighing 1.06 kg wraps a gasket-mounted polycarbonate plate and five layers of sound-dampening foam for a low-pitched, cushioned bottom-out. PBT and PC keycaps resist shine over long sessions. Tri-mode connectivity covers wired USB-C, Bluetooth and 2.4 GHz wireless via the included Type-A receiver, while an 8000 mAh rechargeable battery powers dual independent RGB backlighting systems for extended cable-free use.

Hot-Swap Socket Switch Variety Pack In The Box

The hot-swap PCB accepts 3-pin and 5-pin switches without soldering, letting owners swap the pre-installed linear switches in seconds. The package includes a keycap and switch 2-in-1 puller, a cleaning brush, a cleaning cloth, a USB Type-A to Type-C cable, the 2.4 GHz receiver and four extra switches: one Kailh Platycodon, one Kailh Crackle Ice Box, one KTT Silent Blue and one KTT Baby White, so users can audition tactile, clicky or silent feel immediately.
