98% Compact Layout with Volume Knob

The Redragon K742 is a 98% layout mechanical gaming keyboard that retains a number pad while saving desk space. It features a built-in multimedia volume knob for quick media control. Tri-mode connectivity covers Bluetooth 5.0, 2.4 GHz wireless and USB-C wired operation. The board uses pre-lubed linear switches with a 40 gf actuation force and 3.6 mm total travel.

Hot-Swap PCB and Gasket Mount

The hot-swappable PCB accepts both 3-pin and 5-pin switches without soldering, and a 2-in-1 puller is included for quick changes. A gasket structure with five layers of sound-absorbing padding reduces ping and hollow noise. South-facing RGB LEDs shine through double-shot PBT keycaps. The keyboard connects to up to three devices and switches between them with dedicated shortcuts.

Check OS Shortcuts and Dongle Storage

Verify that the dedicated Windows and macOS shortcut keys match your daily workflow before ordering. The USB dongle stores inside the keyboard chassis, so confirm the compartment is accessible on your desk setup. Battery life varies with RGB brightness and wireless mode; the board recharges via USB-C. No software installation is required for basic functionality.

Questions about this item

How do I confirm the gasket structure and 5-layer padding are giving the intended silent typing feel after setup?

Press several keys and listen for a muted thock sound without ping or rattle; the pre-lubed RCP POM linear switches should feel smooth with a 40±10 gf actuation force and 3.6 mm total travel.

What items are included and what must I purchase separately to start using the keyboard?

The box contains the K742 keyboard, 4 spare switches, a brand logo sticker, a USB-C wired cable, a quick-start manual, and a 2-in-1 keycap/switch puller; no extra accessories are required for tri-mode operation.

Which version should I choose if I want the compact 98% layout with a volume knob and hot-swappable sockets?

The K742 is the single model offered; it provides the 98% layout, multimedia volume knob, gasket mount, tri-mode connectivity (Bluetooth 5.0/2.4 GHz/USB-C), and hot-swappable 3-pin/5-pin PCB sockets.
