Introduction
This manual provides instructions for the installation and maintenance of ZUIDID Rubber Conductive Buttons for NES/FC (Family Computer) controllers. These high-quality replacement parts are designed to restore responsiveness to your controller's D-Pad and other main buttons by replacing worn-out conductive pads.
Setup and Installation
The conductive rubber buttons serve as the contact points between the controller's buttons and the main circuit board. Proper installation is crucial for optimal performance.
Identifying Your Controller Version
It is important to identify whether your NES/FC controller is a Japan version or a Pal/USA version, as the D-Pad rubber contacts may differ slightly in design. The white conductive rubbers are generally universal, but the black D-Pad rubber may vary.

Installation Steps
- Disassembly: Carefully open your NES/FC controller. This typically involves removing screws from the back casing. Refer to specific controller disassembly guides if you are unsure.
- Remove Old Pads: Locate the existing conductive rubber pads under the D-Pad and other buttons. Gently remove the old, worn-out pads.
- Clean Contacts: Clean the contact points on the controller's circuit board and the plastic buttons to ensure good conductivity. Use a soft, dry cloth or isopropyl alcohol if necessary.
- Insert New Pads: Place the new ZUIDID conductive rubber pads into their respective positions. Ensure they are correctly aligned with the buttons and the circuit board contact points. Pay close attention to the D-Pad rubber to ensure you are using the correct version for your controller.
- Reassembly: Carefully reassemble the controller, ensuring all components are properly seated before securing the casing with screws.
Operation
Once installed, the new conductive rubber buttons will restore the tactile feel and electrical conductivity of your controller's buttons. Pressing a button will now properly register input on your NES or FC console, allowing for responsive gameplay.
Maintenance
To ensure the longevity and continued performance of your conductive rubber buttons and controller:
- Keep your controller clean and free from dust and debris.
- Avoid spilling liquids on the controller, as this can damage the conductive material.
- Store the controller in a dry environment away from extreme temperatures.
Troubleshooting
Buttons are unresponsive after installation:
- Check Pad Alignment: Ensure that each conductive rubber pad is correctly seated and aligned with both the physical button and the corresponding contact on the circuit board.
- Verify Version: Double-check that you have used the correct D-Pad rubber version (JP/EU/US) for your specific controller model. Refer to Figure 1.
- Inspect Circuit Board: Examine the circuit board for any visible damage or corrosion on the contact points. Clean if necessary.
- Re-seat Components: Disassemble and reassemble the controller, paying close attention to each step to ensure no components are pinched or misaligned.
