3. Package Contents
Your package should contain the following item:
- 1 x CROWN 30mm Silent 203-S Push Button (in your chosen color)
4. Installation
The CROWN 203-S push button is designed for easy screw-in installation and is compatible with most standard arcade joysticks, including many Hori and MadCatz models. Ensure your mounting surface has a 30mm diameter hole.
- Prepare the Mounting Hole: Verify that the mounting hole on your joystick panel or arcade cabinet is 30mm in diameter. The maximum compatible panel thickness is 10mm.
- Disassemble the Button (if necessary): The button typically comes assembled. To install, you may need to unscrew the clear retaining ring from the button body.
- Insert the Button: Place the button body (with the plunger and switch attached) through the front of the mounting hole.
- Secure the Button: From the back of the panel, screw the retaining ring onto the threaded body of the button until it is finger-tight and secure. Do not overtighten.
- Connect Wiring: The Cherry MX Silver Switch has two terminals. Connect your arcade joystick's signal and ground wires to these terminals. Polarity typically does not matter for simple switch connections.
- (Optional) LED Installation: If you wish to add an LED (not included), the button is designed to accommodate a 3mm LED. Insert the LED into the designated slot on the button body and connect it to your LED power source, ensuring correct polarity.

5. Operation
Once installed and wired correctly, the CROWN 203-S push button operates like any standard arcade button. Press the button to activate the Cherry MX Silver Switch, sending a signal to your connected device. The silent design ensures minimal audible click during actuation, providing a quieter gaming experience.
6. Maintenance
To ensure the longevity and optimal performance of your CROWN 203-S push button, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the surface of the button. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the switch mechanism.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents, as these can damage the ABS plastic and printed legends.
- Inspection: Periodically check the wiring connections to ensure they are secure.
7. Troubleshooting
If you encounter issues with your push button, consider the following:
- Button Not Registering:
- Check all wiring connections to ensure they are secure and correctly attached to the switch terminals and your control board.
- Verify that the switch itself is properly seated within the button housing.
- Test with another known-working button or switch if available, to isolate the problem.
- Button Feels Stiff/Sticky:
- Ensure the button is not overtightened by the retaining ring, which can impede plunger movement.
- Check for any debris or foreign objects that might be obstructing the button's travel.
8. User Tips
- For optimal performance in competitive fighting games, ensure all connections are solid to prevent input lag or missed commands.
- Experiment with different button layouts on your arcade stick or HITBOX to find what feels most comfortable and efficient for your playstyle.
- While the button is silent, the tactile feedback of the Cherry MX Silver switch is still present, providing a satisfying response without the loud click.
