The Red PBS-11B 2PIN 12mm No Lock Push Button Momentary Switch is a type of momentary push-button switch designed for various IoT applications. It features a compact design, a red cap, and a 12mm diameter. This switch has two pins and can handle up to 3A of current at 250V.
Pinouts:
The Red PBS-11B 2PIN 12mm No Lock Push Button Momentary Switch has two pins, labeled as follows:
Pin 1:
Function: Normally Open (NO) pin
Description: When the push button is not pressed, this pin is disconnected from Pin 2. When the push button is pressed, this pin connects to Pin 2, allowing the circuit to be completed.
Pin 2:
Function: Common (COM) pin
Description: This pin is connected to the power source or the circuit being controlled. When the push button is pressed, Pin 1 connects to this pin, allowing the circuit to be completed.
Connection Structure:
Here's a step-by-step guide to connect the pins:
Typical Connection:
1. Connect Pin 2 (COM) to the power source or the circuit being controlled: This can be a positive voltage supply, a microcontroller output, or any other circuit element that needs to be controlled by the push-button switch.
2. Connect Pin 1 (NO) to the load or the circuit element being controlled: This can be an LED, a relay, a buzzer, or any other device that you want to turn on or off when the push button is pressed.
Example Connection Diagram:
Suppose we want to use the Red PBS-11B 2PIN 12mm No Lock Push Button Momentary Switch to control an LED lamp. Here's an example connection diagram:
Pin 2 (COM) Positive terminal of the power supply (e.g., 5V)
Pin 1 (NO) LED lamp's positive terminal
LED lamp's negative terminal Ground (GND)
When the push button is not pressed, the circuit is open, and the LED lamp is off. When the push button is pressed, Pin 1 connects to Pin 2, completing the circuit and turning on the LED lamp.
Important Notes:
Always ensure the switch is used within its rated current and voltage limits (3A, 250V) to prevent damage or electrical shock.
Use proper wiring and insulate connections to prevent electrical shorts or faults.
Make sure to mount the switch securely and follow proper installation guidelines to prevent mechanical damage or malfunction.
By following this documentation, you should be able to correctly understand and connect the Red PBS-11B 2PIN 12mm No Lock Push Button Momentary Switch in your IoT projects.

The switch operates as a momentary push-button switch. When the button is pressed, the normally open (NO) pin is connected to the common (COM) pin, allowing current to flow. When the button is released, the connection is broken, and the circuit is open.

Code Examples

### Example 1: Basic LED Control using Arduino

In this example, we'll use the Red PBS-11B switch to control an LED connected to an Arduino board.

Hardware:

Red PBS-11B switch
 Arduino Board (e.g., Arduino Uno)
 LED
 Resistor (e.g., 220)
 Breadboard and jumper wires

Software:

```cpp
const int ledPin = 13;  // choose a digital pin for the LED
const int buttonPin = 2;  // choose a digital pin for the switch

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

void loop() {
  int buttonState = digitalRead(buttonPin);
  if (buttonState == HIGH) {
    digitalWrite(ledPin, HIGH);  // turn the LED on
  } else {
    digitalWrite(ledPin, LOW);  // turn the LED off
  }
}
```

Explanation:

In this example, we connect the switch to digital pin 2 on the Arduino board, and the LED to digital pin 13. The `setup()` function configures the pins as input and output, respectively. In the `loop()` function, we read the state of the switch using `digitalRead()`. If the switch is pressed (HIGH), we turn the LED on using `digitalWrite()`. Otherwise, we turn the LED off.

### Example 2: Raspberry Pi GPIO Control using Python

In this example, we'll use the Red PBS-11B switch to control a GPIO pin on a Raspberry Pi using Python.

Hardware:

Red PBS-11B switch
 Raspberry Pi (e.g., Raspberry Pi 4)
 Breadboard and jumper wires

Software:

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

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Define the GPIO pins
button_pin = 17
output_pin = 23

# Set up the GPIO pins as input and output
GPIO.setup(button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(output_pin, GPIO.OUT)

try:
    while True:
        button_state = GPIO.input(button_pin)
        if button_state == False:
            GPIO.output(output_pin, GPIO.HIGH)  # turn the output on
        else:
            GPIO.output(output_pin, GPIO.LOW)  # turn the output off
        time.sleep(0.1)
except KeyboardInterrupt:
    GPIO.cleanup()
```

Explanation:

In this example, we connect the switch to GPIO pin 17 on the Raspberry Pi, and an output pin (e.g., a relay or an LED) to GPIO pin 23. We use the RPi.GPIO library to interact with the GPIO pins. The script reads the state of the switch using `GPIO.input()` and sets the output pin accordingly using `GPIO.output()`.
