Compact 75% Layout

The WISDUM Mercury K1 is a 75% wireless mechanical keyboard built around a compact layout that retains the function row and navigation cluster. An aluminium alloy exoskeleton with a gradient black finish supplies structural rigidity while keeping the unit light enough for transport between workstations. Gamers and typists who want a smaller footprint without losing dedicated arrow keys will find the form factor practical.

Gasket Mount and Linear Switches

A gasket-mounted structure paired with a flexible polycarbonate plate and five layers of sound-dampening foam absorbs vibration during long sessions, keeping the acoustic profile consistent rather than growing hollow over time. Custom GravaStar x Kailh linear switches deliver a 40gf actuation force with 1.5mm pre-travel and 3.5mm total travel, so repeated keystrokes stay smooth and predictable during extended play or work marathons.

Tri-Mode Connectivity

The keyboard operates over wired USB-C, Bluetooth 5.0, or 2.4GHz wireless, letting you switch between three devices without re-pairing. Compatibility with both Windows and Mac means a single board serves mixed-OS setups. Buyers who need wired-only simplicity or more than three simultaneous device slots should look elsewhere.

Questions about this item

How loud are the 40gf linear switches and five foam layers after hours of typing?

The 40gf actuation force and 1.5mm pre-travel keep each press light, while the gasket mount and five foam layers absorb vibration for a quiet, consistent sound profile during long sessions.

Do I need a free USB-C port or a 2.4GHz dongle to use the keyboard wirelessly?

Wireless use requires the included 2.4GHz receiver in a USB-A port; Bluetooth 5.0 works without a dongle, and wired mode uses a USB-C cable.

Will the 75% layout and hot-swap sockets fit my existing keycap sets and switch stash?

The 75% layout follows standard key sizing, and the hot-swap sockets accept three-pin and five-pin mechanical switches so you can reuse compatible keycaps and switches.
