How to Use Arcade Button (white): Examples, Pinouts, and Specs

The Arcade Button (White) is a push-button switch commonly used in arcade machines and gaming consoles. It features a durable plastic housing, a white-colored cap, and a spring-loaded mechanism for easy activation. This button provides tactile feedback, making it ideal for user interaction in gaming, DIY electronics projects, and control panels. Its robust design ensures long-lasting performance even under frequent use.

• Arcade gaming machines
• DIY gaming controllers
• Control panels for industrial or hobbyist projects
• Interactive kiosks and exhibits
• Custom electronics projects requiring user input

The Arcade Button (White) typically has two terminals for electrical connections:

1. Mounting the Button:
   Drill a 28mm hole in your panel or enclosure. Insert the button into the hole and secure it using the included mounting nut.

2. Wiring the Button:

   • Connect the COM terminal to the ground (GND) of your circuit.
   • Connect the NO terminal to the input pin of your microcontroller or circuit.
   • Use quick-connect spade connectors for secure and reliable connections.

3. Pull-up Resistor:
   If connecting to a microcontroller (e.g., Arduino), ensure the input pin has a pull-up resistor (internal or external) to prevent floating signals when the button is not pressed.

4. Testing the Button:

   • When the button is pressed, the circuit between the COM and NO terminals closes, sending a signal to your circuit.
   • Release the button to open the circuit.

Below is an example of how to connect and use the Arcade Button (White) with an Arduino UNO:

• COM terminal → GND on Arduino
• NO terminal → Digital Pin 2 on Arduino

// Arcade Button Example with Arduino UNO
// This code reads the state of the button and turns on an LED when pressed.

const int buttonPin = 2;  // Pin connected to the NO terminal of the button
const int ledPin = 13;    // Built-in LED on Arduino UNO

void setup() {
  pinMode(buttonPin, INPUT_PULLUP); // Set button pin as input with internal pull-up
  pinMode(ledPin, OUTPUT);          // Set LED pin as output
}

void loop() {
  int buttonState = digitalRead(buttonPin); // Read the button state

  if (buttonState == LOW) { // Button pressed (LOW due to pull-up resistor)
    digitalWrite(ledPin, HIGH); // Turn on the LED
  } else {
    digitalWrite(ledPin, LOW);  // Turn off the LED
  }
}

• Debouncing: Mechanical buttons may produce noise or multiple signals when pressed. Use software debouncing or a capacitor across the terminals to stabilize the signal.
• Voltage Compatibility: Ensure the button's voltage rating matches your circuit's requirements.
• Durability: Avoid excessive force or improper mounting to maintain the button's lifespan.

1. Can I use this button with a Raspberry Pi?
   Yes, the Arcade Button (White) can be used with a Raspberry Pi. Connect the NO terminal to a GPIO pin and the COM terminal to GND. Use a pull-up resistor or enable the internal pull-up in your code.

2. Is the button waterproof?
   No, this button is not waterproof. Avoid using it in environments with high moisture or exposure to liquids.

3. Can I use this button for high-power applications?
   The button is rated for 1A at 125V AC or 0.5A at 250V AC. For higher power applications, use a relay or transistor to handle the load.

4. How do I clean the button?
   Use a soft cloth and isopropyl alcohol to clean the surface. Avoid using excessive liquid or harsh chemicals.

By following this documentation, you can effectively integrate the Arcade Button (White) into your projects and troubleshoot any issues that arise.
