Compact 75% mechanical combo

The Redragon S136 bundles a 78-key K628 keyboard with a 7200 DPI M693 mouse. Both devices connect through a single 2.4 GHz dongle and also support Bluetooth. The keyboard uses linear red switches and keeps dedicated arrow and number keys in a 75 percent layout. The right-handed optical mouse offers seven programmable buttons and a scroll wheel.

Hot-swap sockets and shared receiver

The keyboard features hot-swap sockets compatible with 99.8 percent of three-pin and five-pin switches, allowing switch changes without soldering. A single USB receiver handles both keyboard and mouse, freeing a port and removing dongle confusion. Keycaps and chassis are black with per-key RGB lighting. The mouse shape suits all grip styles and tracks optically.

Upgrades full-size wired sets

This combo replaces a full 104-key wired keyboard and separate mouse for users who want wireless freedom and a smaller desk footprint. The jump is worth it when you need hot-swap flexibility, unified software for lighting and macros, and a single dongle for both peripherals. Buyers who require a built-in palm rest or a left-handed mouse should look elsewhere.

Questions about this item

How does the single 2.4 GHz dongle handle both the keyboard and mouse simultaneously?

The shared receiver pairs both devices at once, so only one USB port is occupied and there is no need to swap or track separate dongles.

Will the 75% 78-key board fit my existing keycap sets and case?

The compact 75% layout keeps standard spacing for the 78 keys, including dedicated arrows and number row, so most aftermarket keycap kits and 75% cases are compatible.

What is the hot-swap socket process and which mistake should I avoid?

Pull the old switch straight out with a switch puller, align the new 3-pin or 5-pin switch pins, and press evenly until seated; the common error is forcing a switch in at an angle, which bends pins.
