Code Examples

Component Documentation: 3A 250V AC SPST ON-OFF Round Rocker Switch
Overview
The 3A 250V AC SPST ON-OFF Round Rocker Switch is a type of electrical switch used to control the flow of electrical current in IoT applications. It is a single-pole single-throw (SPST) switch, meaning it has two terminals and can be used to turn a circuit on or off. This switch is designed to handle up to 3A of current and is rated for 250V AC, making it suitable for a wide range of IoT projects.
Pinout
The switch has two terminals:
Terminal 1 (T1): Input terminal, connected to the power source
 Terminal 2 (T2): Output terminal, connected to the load (e.g., LED, motor, etc.)
How to Use
To use the 3A 250V AC SPST ON-OFF Round Rocker Switch, follow these general steps:
1. Connect the input terminal (T1) to a power source (e.g., wall adapter, battery, etc.).
2. Connect the output terminal (T2) to the load (e.g., LED, motor, etc.).
3. Flip the switch to the "ON" position to allow current to flow from the power source to the load.
4. Flip the switch to the "OFF" position to disconnect the power source from the load.
Code Examples
Here are two code examples that demonstrate how to use the 3A 250V AC SPST ON-OFF Round Rocker Switch in different contexts:
Example 1: Controlling an LED using an Arduino Uno
In this example, we will use the switch to control an LED connected to an Arduino Uno board.
```c++
const int ledPin = 13;  // LED connected to digital pin 13
const int switchPin = 2;  // Switch connected to digital pin 2
void setup() {
  pinMode(ledPin, OUTPUT);
  pinMode(switchPin, INPUT);
}
void loop() {
  int switchState = digitalRead(switchPin);
  if (switchState == HIGH) {
    digitalWrite(ledPin, HIGH);  // Turn on the LED
  } else {
    digitalWrite(ledPin, LOW);  // Turn off the LED
  }
}
```
Example 2: Controlling a Relay using a Raspberry Pi
In this example, we will use the switch to control a relay module connected to a Raspberry Pi.
```python
import RPi.GPIO as GPIO
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Define switch and relay pins
switch_pin = 17
relay_pin = 23
# Set up switch and relay pins as input and output, respectively
GPIO.setup(switch_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(relay_pin, GPIO.OUT)
try:
    while True:
        switch_state = GPIO.input(switch_pin)
        if switch_state:
            GPIO.output(relay_pin, GPIO.HIGH)  # Turn on the relay
        else:
            GPIO.output(relay_pin, GPIO.LOW)  # Turn off the relay
except KeyboardInterrupt:
    GPIO.cleanup()
```
In both examples, the switch is connected to a digital input pin on the microcontroller (Arduino Uno or Raspberry Pi), and the state of the switch is read to control the output (LED or relay).
