- Avoid spraying liquids directly onto the keyboard.

The Yoidesu keyboard features hot-swappable switches, allowing for easy replacement without soldering. Use the included keycap puller and switch puller (often integrated with the keycap puller) for this process.
- Removing a Keycap: Gently attach the keycap puller to the keycap you wish to remove and pull upwards until it detaches.
- Removing a Switch: After removing the keycap, use the switch puller to grasp the top and bottom clips of the switch. Apply gentle pressure and pull the switch straight up.
- Installing a New Switch: Align the pins of the new switch with the holes on the PCB. Press down firmly until the switch clicks into place. Ensure it is seated correctly and not bent.
- Installing a Keycap: Place the keycap over the switch stem and press down gently until it is secure.
