4.4 Hall Effect Magnetic Switches and Rapid Trigger
The YK61 utilizes Hall Effect magnetic switches, which detect key presses using magnetic fields, offering precise and consistent actuation without physical contact. This design reduces wear and tear and allows for advanced features:
- Adjustable Actuation: Customize the actuation point from 0.1mm to 4.0mm with 0.1mm sensitivity.
- Rapid Trigger Mode: This feature allows keys to reset dynamically, enabling faster repeated inputs and quick-stop shooting in games.

6. Troubleshooting
- Keyboard not responding: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.
- RGB lighting not working: Check Fn key combinations for lighting control. If using the driver, ensure it is installed correctly and the keyboard is in wired mode.
- Keys not registering or double-typing: This may indicate an issue with the switch. Due to hot-swap capability, try replacing the affected switch. Ensure the driver software is up to date.
- Driver software not detecting keyboard: Ensure the keyboard is connected via USB-C and that the driver is the correct version for your operating system (Windows only). Restart your computer and try again.
- Difficulty seeing side-printed keycaps in low light: While the keyboard has RGB backlighting, the visibility of side-printed legends can vary based on ambient light and specific RGB settings. Adjust lighting brightness or use direct light if needed.
