Compact 75% Layout with Control Knob

The Mercury K1 Pro is a 75% wireless mechanical gaming keyboard with 79 keys and a programmable control knob. Its streamlined form factor suits gamers and typists who want full function-row access without a full-size footprint. The ambidextrous design works for left- or right-handed users. Hot-swappable sockets let you change switches without soldering.

Verify Connectivity and Switch Preference

Ensure your device has a free USB-A port for the 2.4GHz receiver or a USB-C port for wired use. The keyboard also pairs via Bluetooth for laptops and tablets. The stock GravaStar x Kailh Speedy Mint linear switches have a 45gf actuation force and 1.2mm pre-travel. If you prefer tactile or clicky feedback, plan to use the four extra switches included or source alternatives.

Aluminium Frame and Gasket Mount

A matte black aluminium alloy frame weighing 1.18kg provides a rigid, skeletal chassis that resists flex during intense sessions. The gasket-mounted FR4 plate and five layers of sound-dampening foam create a cushioned, quiet typing feel. Dual independent RGB systems shine through double-shot PBT pudding keycaps with dye-sublimated legends. The 8000mAh battery supports long wireless sessions across all three connection modes.
