This component is available in a pack of 10, making it an ideal choice for prototyping, development, and production purposes.

Functionality

The 12x12x7.3mm Tactile Push Button Switch is a momentary action switch, meaning it returns to its original position once the pressure is released. When pressed, the switch makes contact, allowing electrical current to flow through the circuit. When released, the switch breaks the contact, interrupting the current flow. This switch is commonly used in IoT devices, robotics, and other electronic projects that require a simple, reliable, and durable human-machine interface.

Pin Configuration

Component Documentation: 12x12x7.3mm Tactile Push Button Switch (Pack of 10)
Overview
The 12x12x7.3mm Tactile Push Button Switch is a compact, surface-mountable switch designed for use in a wide range of IoT applications. This documentation provides a detailed explanation of the switch's pins, their functions, and how to connect them.
Pinout
The switch has 4 pins, labeled as follows:
Pin 1: NC (Normally Closed)
Function: Connects to the circuit when the button is not pressed
Description: This pin is connected to the circuit when the button is in its normal, unpressed state.
Pin 2: COM (Common)
Function: The common pin that connects to the circuit when the button is pressed
Description: This pin acts as a reference point for the switch and is connected to the circuit when the button is pressed.
Pin 3: NO (Normally Open)
Function: Connects to the circuit when the button is pressed
Description: This pin is connected to the circuit when the button is pressed, and is normally open when the button is not pressed.
Pin 4: No connection
Function: No internal connection
Description: This pin is not connected to any internal component and should not be used.
Connection Structure
To connect the switch to a circuit, follow these steps:
1. Connect Pin 2 (COM) to a ground point or a reference voltage:
This provides a common reference point for the switch.
2. Connect Pin 1 (NC) to the circuit's normally closed path:
This pin connects to the circuit when the button is not pressed, allowing the circuit to function normally.
3. Connect Pin 3 (NO) to the circuit's normally open path:
This pin connects to the circuit when the button is pressed, allowing the circuit to function in its alternative state.
Example Connection Diagram
Here's an example of how to connect the switch to a simple LED circuit:
Pin 2 (COM) -> Ground
Pin 1 (NC) -> Resistor -> LED -> Ground
Pin 3 (NO) -> Resistor -> LED -> Ground
In this example, the LED is normally off (connected to Pin 1). When the button is pressed, the LED turns on (connected to Pin 3).

Connectivity and Usage

The switch has two pins: one for the input (pin 1) and one for the output (pin 2). When the button is pressed, the two pins are connected, allowing the circuit to be closed.

Code Examples

Here are three code examples demonstrating how to use the 12x12x7.3mm Tactile Push Button Switch in different contexts:

Example 1: Basic Switch Usage with Arduino

In this example, we'll connect the switch to digital pin 2 on an Arduino board and use it to toggle an LED on and off.
```c
const int switchPin = 2;  // The pin connected to the switch
const int ledPin = 13;   // The pin connected to the LED

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

void loop() {
  int switchState = digitalRead(switchPin);
  if (switchState == HIGH) {
    digitalWrite(ledPin, HIGH); // Turn the LED on
  } else {
    digitalWrite(ledPin, LOW);  // Turn the LED off
  }
  delay(50); // Debouncing
}
```

Example 2: Using the Switch as a Debounced Input with Raspberry Pi (Python)
```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
switch_pin = 17  # The pin connected to the switch
GPIO.setup(switch_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

while True:
    if GPIO.input(switch_pin) == GPIO.LOW:
        print("Switch pressed!")
        # Perform an action here, such as sending a signal or triggering an event
    time.sleep(0.05)  # Debouncing delay
```

Example 3: Using the Switch as a Trigger for an ESP32 Microcontroller (C++)
```c
#include <WiFi.h>

const int switchPin = 23;  // The pin connected to the switch

void setup() {
  pinMode(switchPin, INPUT);
  Serial.begin(115200);
}

void loop() {
  int switchState = digitalRead(switchPin);
  if (switchState == HIGH) {
    Serial.println("Switch pressed!");
    // Perform an action here, such as sending a message over Wi-Fi or triggering an event
    delay(50); // Debouncing
  }
}
```
These examples demonstrate how to use the 12x12x7.3mm Tactile Push Button Switch in various contexts, including Arduino, Raspberry Pi, and ESP32 microcontrollers.
