Pinout

Arduino Wiring

• Connect one pin of the switch to a digital input pin on the Arduino (example: D2).
• Connect the other pin to GND.
• Enable the internal pull-up resistor in Arduino to read HIGH when the button is not pressed.

Arduino Example Code

const int buttonPin = 2;    // Pin connected to switch
const int ledPin = 13;      // Pin connected to onboard LED

int buttonState = 0;

void setup() {
  pinMode(buttonPin, INPUT_PULLUP); // Enable internal pull-up resistor
  pinMode(ledPin, OUTPUT);
  Serial.begin(9600);
}

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

  if (buttonState == LOW) { // Button pressed (active LOW)
    digitalWrite(ledPin, HIGH); // Turn on LED
    Serial.println("Button Pressed");
  } else {
    digitalWrite(ledPin, LOW);  // Turn off LED
  }

  delay(50); // Debounce delay
}

Tips & Information

• The switch is active LOW when using internal pull-up resistors: pressing connects the pin to GND.
• Debouncing is important; a simple software delay or a hardware capacitor can help prevent false triggering.
• This tactile switch can be mounted directly on a breadboard for rapid prototyping.
• Combine multiple switches with arrays or keypads for advanced user interfaces.
• Ensure not to exceed the rated current (50mA) to avoid damage.
