Typical Connection: Connect to a microcontroller or circuit ground.
Pin 2: COM (Common)
Function: Serves as the common connection point for the switch.
State: Always connected to either NC or NO.
Typical Connection: Connect to a microcontroller or circuit power source.
Pin 3: NO (Normally Open)
Function: Connects to the circuit when the switch is pressed.
State: Open when the switch is not pressed, closed when the switch is pressed.
Typical Connection: Connect to a microcontroller or circuit input.
Pin 4: GND (Ground)
Function: Provides a ground connection for the switch.
State: Always connected to ground.
Typical Connection: Connect to the circuit ground or a microcontroller's ground pin.
Pin Connection Structure
The following is a typical connection structure for the 4-Pins DIP Momentary Square Tactile Push Button Switch:

Code Examples

### Example 1: Basic Debouncing with Arduino

In this example, we'll use the switch to control an LED connected to digital pin 13 on an Arduino board.

```cpp
const int buttonPin = 2;  // Connect switch to digital pin 2
const int ledPin = 13;   // Connect LED to digital pin 13
int buttonState = 0;     // Store the current button state

void setup() {
  pinMode(buttonPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop() {
  buttonState = digitalRead(buttonPin);
  if (buttonState == HIGH) {
    digitalWrite(ledPin, HIGH);
  } else {
    digitalWrite(ledPin, LOW);
  }
  delay(50); // Debounce time
}
```

### Example 2: Using with Raspberry Pi and Python

In this example, we'll use the switch to toggle an LED connected to GPIO pin 17 on a Raspberry Pi.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
button_pin = 17  # Connect switch to GPIO pin 17
led_pin = 17    # Connect LED to GPIO pin 17

GPIO.setup(button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(led_pin, GPIO.OUT)

try:
    while True:
        button_state = GPIO.input(button_pin)
        if button_state == False:
            GPIO.output(led_pin, GPIO.HIGH)
        else:
            GPIO.output(led_pin, GPIO.LOW)
        time.sleep(0.05)  # Debounce time
except KeyboardInterrupt:
    GPIO.cleanup()
```

Note: In both examples, a debouncing mechanism is used to prevent the code from reading multiple button presses as separate events. The debouncing time is set to 50ms, but you may need to adjust this value depending on your specific application.
