Setup and Installation
The arcade button requires DIY assembly. Follow these steps for proper installation:
- Prepare Mounting Hole: Ensure your control panel or mounting surface has a circular hole of approximately 100mm (3.94 inches) in diameter to accommodate the button.
- Insert Button Body: Place the main button body (yellow dome) through the mounting hole from the top.
- Secure with Holder: From the underside of the mounting surface, slide the gasket onto the threaded shaft of the button, followed by the fixed nut (button holder). Tighten the fixed nut securely to hold the button in place.
- Install Microswitch: Attach the microswitch to the bracket on the underside of the button assembly. The microswitch should align so that its plunger is activated when the button is pressed.
- Connect LED Light: Insert the LED light into its designated slot within the button assembly. Note that LED lights have positive and negative poles. Ensure correct polarity when connecting to a DC 12V power source. Incorrect polarity will prevent the LED from lighting up but will not damage the microswitch.
- Wire Connections:
- Microswitch: Connect your control signals to the microswitch terminals. The microswitch contacts are normally open (NO) and close when the button is pressed. Refer to your arcade system's wiring diagram for specific connections (e.g., Common (COM) and Normally Open (NO) terminals).
- LED Light: Connect the LED light to a DC 12V power supply. Observe polarity.

Operating Instructions
Once installed and wired correctly, the NDNCZDHC 100mm Massive Arcade Button operates as a standard momentary push-button switch with illumination.
- Button Function: Press the yellow dome to activate the microswitch. This will send a signal to your connected device (e.g., arcade game, vending machine).
- LED Illumination: When the LED is powered by a DC 12V source, it will illuminate the button. The illumination may not be perfectly even across the entire button face due to its large size and shallow depth.
Maintenance
The NDNCZDHC 100mm Massive Arcade Button is designed for durability and requires minimal maintenance.
- Cleaning: Use a soft, damp cloth to wipe the surface of the button. Avoid abrasive cleaners or solvents, as these may damage the plastic.
- Inspection: Periodically check the wiring connections to the microswitch and LED for any signs of wear or looseness. Ensure the fixed nut remains tight.
- Component Replacement: If the microswitch or LED light fails, they can be replaced independently. Ensure replacement parts match the original specifications (e.g., 12V DC LED).
