Nintendo NEW Nintendo 3DS LL Dedicated ABXY Button Diaphragm Switch Seal Sticker Repair Repair Replacement Compatible Parts Maintenance Parts For Right Color Buttons 1 piece ■ Is the Nintendo 3DS cross key stiff!? Symptoms of poor response without a pressing feel are improved by replacing the internal seal! ■ If used for many years, the 3DS cross key's conductive parts may become dirty or rusty due to aging, causing electrical signals to stop flowing, resulting in extremely poor responsiveness. Replacing this seal may improve such situations. ■ If there is rust or dirt on the main unit's board, please clean the surface using a solvent. ■ Issues with the cross key can be caused by various factors other than the diaphragm. If the problem lies elsewhere, replacing only this part will not resolve the issue. Please assess the problem area at your own risk. ■ Bulk product. There is no packaging or instruction manual, so please search the internet for replacement methods.
