Mercury K1 Pro 75% Layout

The GravaStar Mercury K1 Pro is a wireless mechanical gaming keyboard with a compact 75% layout that includes 79 keys plus a rotary knob. An aluminum alloy frame provides a rigid chassis while the gasket-mounted design uses five layers of foam dampening to reduce resonance. Custom Kailh Speedy Mint linear switches deliver a 45 gf actuation force and 1.2 mm pre-travel for quick response.

Gamers and typists wanting tri-mode flexibility

This keyboard suits users who want to switch between wired USB-C, 2.4 GHz wireless and Bluetooth without changing hardware. The 8000 mAh rechargeable battery supports long cable-free sessions. Buyers who need a full-size numpad or dedicated macro column will find the streamlined layout restrictive for spreadsheet work.

Hot-swappable sockets simplify switch changes

The board ships with a 2-in-1 puller so extra switches can be installed without soldering. Four sample switches are included for experimentation. The gasket structure and multiple foam layers make reassembly slightly tighter than a tray-mount board, so first-time builders should seat the PCB carefully to avoid pinching the dampening strips.
