Hot-Swap Switch Replacement
The K500-B68 supports 3-pin hot-swappable mechanical switches, allowing you to change switches without soldering. This enables customization of typing feel and sound.
- To Remove a Switch: Use the provided switch puller tool. Gently grip the switch from the top and bottom, then pull upwards with even pressure until the switch detaches from the PCB.
- To Install a Switch: Align the pins of the new 3-pin mechanical switch with the holes on the PCB. Press down firmly until the switch clicks into place. Ensure the pins are straight before insertion to avoid bending.

Maintenance
- General Cleaning: Regularly clean the keyboard to prevent dust and debris buildup. Use a soft brush or compressed air to remove particles from between the keycaps.
- Keycap Cleaning: For deeper cleaning, keycaps can be removed using a keycap puller. Wash keycaps with mild soap and water, then ensure they are completely dry before reattaching. The Doubleshot ABS+PBT keycaps are designed for high durability and resistant legends.
- Surface Cleaning: Wipe the aluminum top plate with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals.
- Cable Care: Avoid sharp bends or excessive pulling on the USB cable to prevent damage.
Troubleshooting
Keyboard Not Responding
- Check Connection: Ensure the USB cable is securely plugged into both the keyboard and the computer/console. Try a different USB port.
- Restart Device: Restart your computer or gaming console.
- Test on Another Device: Connect the keyboard to another computer to determine if the issue is with the keyboard or the original device.
RGB Lighting Issues
- Check Brightness: Ensure the brightness is not set to minimum (Fn + ↑).
- Cycle Modes: Try cycling through different lighting modes (Fn + \|) to see if the issue persists across all modes.
- Firmware: Check the manufacturer's website for any available firmware updates that might resolve lighting issues.
Keys Not Registering
- Clean Key/Switch: Remove the keycap and inspect the switch for any debris. If hot-swapping, ensure the switch is fully seated and its pins are not bent.
