Compact 75% Layout

The costom WK75 is a 75 percent mechanical keyboard built for gamers and typists who want a smaller footprint without losing the function row and navigation cluster. It uses pre-lubed custom linear switches mounted in a hot-swappable PCB and a gasket structure with multiple sound-damping layers. The aluminium case and topographic colourway give it a distinct look on any desk.

Tri-Mode Connectivity

The board connects via Bluetooth 5.0, 2.4 GHz wireless or USB-C wired modes and can switch between devices with a side shortcut button. RGB backlighting offers 16.8 million colours with twelve music-rhythm effects adjustable by knob or FN combination. Power comes from an included AA battery for wireless use.

Hot-Swappable Switch Sockets

Three-pin and five-pin mechanical switches can be swapped without soldering using the supplied keycap puller and three replacement switches. Custom software allows keymap, macro and RGB redefinition. Buyers who need a full-size layout or a non-mechanical membrane board should look elsewhere.

Questions about this item

How do I pair the keyboard via Bluetooth 5.0 and what step is often missed?

Turn the side mode switch to Bluetooth, hold the designated FN key combination until the indicator flashes, then select the keyboard in the OS Bluetooth menu; the step often missed is holding the FN combo long enough to enter pairing mode.

What maintenance will the hot-swappable Outemu linear switches need over time?

Switches can be pulled with the included keycap puller and replaced with any 3-pin or 5-pin MX-style switch; re-lubing is optional but not required for normal use.

What limit appears first during extended RGB use on the 2.4 GHz wireless link?

The single AA battery drains faster with full-brightness RGB, reducing wireless runtime before a recharge or replacement is needed.
