The Pushbutton_2P is a versatile pushbutton switch manufactured by Custom, with the part ID PushButton_2p. This component features two poles, enabling it to control two separate circuits or functions simultaneously with a single press. It is commonly used in applications requiring momentary switching, such as user interfaces, control panels, and prototyping.
This is a pushbutton-controlled LED circuit with a TA6568 chip that likely drives two LEDs (red and green). Each LED is connected to a pushbutton through the TA6568, allowing the user to toggle the state of the LEDs. The circuit is powered by a 3V battery and includes a JST connector for external interfacing.

This is a dual-channel pushbutton-controlled LED circuit. Each channel uses a pushbutton to activate an NPN transistor switch, which in turn lights up an LED. The circuit operates on a 5V DC supply.

This circuit features an Arduino UNO microcontroller connected to a pushbutton and a 10k Ohm resistor. The pushbutton is powered by the 5V pin of the Arduino, and its state is read through digital pin D2, with the resistor providing a pull-down to ground.

This circuit consists of a 24V power supply unit (PSU) connected to four pushbuttons. Each pushbutton is wired such that pressing it will send a 24V signal to a corresponding general-purpose input (GP In) on a 40-pin connector. The common return path for the pushbuttons is connected to the 0V of the PSU, which is also connected to the common (Com) for input pins on the 40-pin connector, completing the circuit for each button press.

| Pin Number | Description |
|---|---|
| 1 | Pole 1 - Normally Open (NO) Contact |
| 2 | Pole 1 - Common (COM) Contact |

The following example demonstrates how to use the Pushbutton_2P to control an LED with an Arduino UNO. One pole of the pushbutton is used in this example.
// Define pin numbers
const int buttonPin = 2; // Pushbutton connected to digital pin 2
const int ledPin = 13; // LED connected to digital pin 13
// Variable to store button state
int buttonState = 0;
void setup() {
pinMode(buttonPin, INPUT_PULLUP); // Set button pin as input with internal pull-up
pinMode(ledPin, OUTPUT); // Set LED pin as output
}
void loop() {
// Read the state of the pushbutton
buttonState = digitalRead(buttonPin);
// If button is pressed (LOW state due to pull-up resistor)
if (buttonState == LOW) {
digitalWrite(ledPin, HIGH); // Turn on the LED
} else {
digitalWrite(ledPin, LOW); // Turn off the LED
}
}

Multiple Circuits Not Working Simultaneously:
Q: Can I use the Pushbutton_2P to control AC circuits?
A: The Pushbutton_2P is rated for DC circuits up to 50V and 1A. It is not recommended for use in AC circuits unless the ratings are strictly adhered to.
Q: How do I debounce the pushbutton in software?
A: You can use a delay or a state-change detection algorithm in your code to filter out bouncing signals.
Q: Can I use both poles independently?
A: Yes, the two poles are electrically isolated and can be used to control two separate circuits or functions.
Q: What is the lifespan of the Pushbutton_2P?
A: The mechanical lifespan is rated at 100,000 cycles under normal operating conditions.
