Full-Size Hot-Swap Mechanical Keyboard

The Redragon K556 SE is a full-size wired mechanical keyboard built around a brushed aluminium base. It ships with 104 keys and factory-fitted linear Red switches that are quiet and smooth. The board uses a true hot-swap socket design rated for 99.8 % switch compatibility, supporting both 3-pin and 5-pin switches without soldering. A 3.5 mm sound-absorbing foam layer sits beneath the PCB to reduce hollow resonance.

Aluminium Base and Hot-Swap Socket Upgrade

This model replaces earlier plastic-chassis keyboards that required desoldering to change switches. The solid aluminium plate adds rigidity and a premium feel, while the upgraded socket structure reduces switch wobble and makes experimentation effortless. The jump is worth it for enthusiasts who want to try different switch types or replace a single faulty switch without specialist tools.

Gradient Keycaps and On-Board RGB Control

The blue gradient shine-through keycaps suit users who want vibrant per-key lighting without software. Eighteen preset backlight modes, plus on-board brightness and speed adjustment, cover most lighting preferences. Buyers who need dedicated macro keys, wireless connectivity, or a compact layout should look elsewhere.

Questions about this item

What size is the aluminium base and how many keys does the full-size layout have?

The keyboard uses a solid aluminium board with a brushed finish and a full-size 104-key layout.

How do I swap the pre-installed Red switches for a different type without soldering?

Pull each switch straight up with a switch puller, align the pins of the new 3-pin or 5-pin switch, and press firmly until seated; the hot-swap sockets accept 99.8 % of market switches.

When should I replace the 3.5 mm sound-absorbing foam underneath the PCB?

Replace the foam if it becomes compressed, torn or loses its damping effect, which changes the typing sound profile.
