Full Size 108 Keys Layout

The Redragon K689 is a full size wired gaming keyboard with 108 keys and four additional shortcut keys. It uses custom linear switches that are factory lubricated for a smooth travel. The gasket mounted structure replaces traditional screw fixing with precision locked covers to add flexibility and reduce rigid noise. The board is aimed at gamers and typists who want a quiet, cushioned feel.

Gasket Mount and Hot Swappable Sockets

The chassis uses a gasket design with three layers of dampening foam including 3.5mm PO foam, IXPE switch foam and bottom socket foam. A silicone gasket sits between the plate and case to absorb hollow sound. Keycaps are a mixed colour set made of plastic and the board includes a keycap puller. Two stage adjustable feet allow the typing angle to be raised for wrist comfort. Hot swappable sockets let you change switches without soldering.

Wired RGB With Software Control

Power is delivered over a wired USB connection so there is no battery to manage. Per key RGB backlighting can be customised through Redragon software where macros and the four shortcut keys can also be remapped. The linear switches and dampening materials keep acoustic output low during extended sessions. The keyboard measures 444 mm by 133 mm by 37 mm.

Questions about this item

What connection does the Redragon K689 use, and what does that limit?

The K689 connects by a single wired USB cable, so it works instantly on any PC without pairing or batteries, but the cable length fixes how far the board can sit from the host.

What are the exact outer dimensions of the K689, and how much desk depth does it need?

The board measures 444 mm wide, 133 mm deep and 37 mm high, so you need at least 133 mm of clear desk depth plus room for the cable exit.

How are the keycaps removed on the K689, and what is the step users often miss?

Use the included keycap puller, hook it under opposite edges of a cap and pull straight up; the step people miss is pulling vertically — tilting the puller bends or snaps the switch stems.
