75% Hot-Swap Keyboard & Mouse Combo

The Redragon S136 Pollux bundles a 75% layout mechanical keyboard with 78 keys and a wireless gaming mouse. The keyboard uses hot-swap sockets compatible with 99.8% of switches for easy customisation. A shared 2.4 GHz dongle connects both peripherals for a clutter-free desk. This set suits gamers and typists who want compact functionality with switch flexibility.

Installation & Common Issues

Plug the single USB dongle into a free port and the pair is recognised instantly without extra drivers. Hot-swap switches pull out with the included tool; align pins carefully to avoid bent contacts. The mouse offers five on-board DPI levels up to 7200, adjustable via software for finer tuning. Some users report occasional wireless interference in crowded 2.4 GHz environments.

Pre-Purchase Checklist

Verify you have an available USB-A port for the shared receiver. Confirm your operating system supports standard HID keyboard and mouse input for full functionality. The 78-key layout omits a dedicated number pad, so ensure that matches your workflow. Battery-powered operation means periodic recharging or replacement is required for both devices.

Questions about this item

How do I confirm the keyboard is registering every keystroke after setup?

Press each of the 78 keys and verify the corresponding character appears on screen; the hot-swap sockets accept 99.8%+ switches so any replacement switch should register identically.

What comes in the box and what must I buy separately?

The bundle includes the 75% K628 keyboard, the M693 mouse and a shared 2.4 GHz dongle; no separate receiver is needed, and the units are battery powered so no cable is required for wireless use.

Which version should I choose between the 75% and a full 104-key layout?

The 78-key 75% layout keeps dedicated arrow and number keys while saving desk space; choose it if you want compactness without losing those clusters.
