Redragon Gwern K662L-G1RS Wireless Mechanical Keyboard – 68-Key Compact Layout, Red Switches, 2.4GHz & Bluetooth, Hot-Swappable – Grey/Black

Description

The Redragon Gwern K662L-G1RS is a compact dual-mode wireless mechanical keyboard designed for gaming, everyday typing, study, and portable desktop setups. It supports both low-latency 2.4GHz wireless connectivity and Bluetooth, allowing it to work with desktop computers, laptops, tablets, and other compatible devices.

Its space-saving 68-key layout retains essential controls and dedicated arrow keys while eliminating the numeric keypad and separate function-key row. The keyboard uses smooth linear Red mechanical switches and supports hot-swapping through its 5-pin switch sockets.

The K662L-G1RS is powered by two replaceable AAA batteries and features intelligent sleep modes to reduce unnecessary power consumption. This model does not include backlighting.

Dual-Mode Wireless Connectivity

The Redragon Gwern supports two wireless connection methods:

2.4GHz Wireless

The included USB receiver provides a responsive wireless connection suitable for gaming, general desktop use, and everyday typing.

The receiver can be stored in the compartment underneath the keyboard when it is not being used, helping prevent it from being lost during transportation.

Bluetooth

Bluetooth connectivity is convenient for compatible laptops, tablets, smartphones, and computers without occupying a USB port.

The keyboard provides three Bluetooth channels, allowing it to pair with multiple compatible devices and switch between them using keyboard shortcuts.

For gaming, the 2.4GHz receiver is generally the preferred connection because it normally provides lower latency than Bluetooth.

Compact 68-Key Layout

The K662L-G1RS uses a compact 68-key layout, sometimes marketed as a 60% gaming keyboard. Functionally, it is closer to a compact 65%-class layout because it retains dedicated arrow keys and several navigation controls.

Removing the numeric keypad and dedicated function-key row gives the keyboard a width of approximately 31cm, creating additional space for mouse movement.

This layout is particularly useful for:

• Small gaming desks
• Low-sensitivity mouse movement
• Portable computer setups
• Home offices
• Student desks
• Laptop users
• Minimalist workstations

Frequently used secondary commands and function keys remain available through Fn shortcuts.

Linear Red Mechanical Switches

The keyboard is equipped with Red mechanical switches designed to provide a smooth, linear keypress without the pronounced tactile bump or click of Brown and Blue switches.

Red switches are suitable for:

• Fast-paced gaming
• Repeated key presses
• Everyday typing
• Users who prefer smooth keystrokes
• Shared spaces where clicky switches may be distracting

The listed switch specifications include an actuation force of approximately 60 ± 15g and total travel of 4.0 ± 0.2mm.

Hot-Swappable Switches

The K662L-G1RS features a hot-swappable PCB with 5-pin mechanical-switch sockets. Compatible switches can be removed and replaced without soldering.

This allows users to:

• Replace a damaged switch
• Experiment with different switch types
• Change the keyboard’s typing feel
• Mix switch types for selected keys
• Maintain the keyboard more easily

Replacement switches must be mechanically and electrically compatible with the keyboard’s sockets.

Full-Key Anti-Ghosting

Full-key anti-ghosting allows the keyboard to register multiple simultaneous keypresses accurately. This is particularly useful during gaming, where movement, modifiers, abilities, and other commands may be pressed at the same time.

English and Arabic Keycaps

The K662L-G1RS version sold in regional markets features English and Arabic key legends, making it suitable for bilingual typing.

The keycaps are manufactured from injection-moulded ABS material. This keyboard does not include illuminated legends because it has no backlighting.

AAA Battery Power

The keyboard operates using two AAA batteries and does not require a charging cable.

Replaceable batteries allow users to install fresh batteries immediately rather than waiting for an internal battery to recharge. Intelligent sleep modes help reduce power usage when the keyboard remains inactive.

Battery operating time depends on factors including:

• Battery quality and capacity
• Selected wireless mode
• Daily usage
• Sleep-mode behaviour
• Distance from the connected device

Two AAA batteries are required. Battery inclusion may vary between retailers.
