Tutorial: How to use the KCD3 Round black 2 position switch

This 2 position switch is ideal for controlling electronic devices that require manual intervention, such as lights or motors. Perfect for beginners and basic projects.

What you need

• KCD3 Round black switch
• Connection wires
• Arduino or electronic circuit
• 250V power supply

Steps

1. 1. Check that the switch supports 15A and 250V.
2. 2. Disconnect the power.
3. 3. Connect the wires to the switch, check the datasheet.
4. 4. Connect the switch pins to the digital pin of your Arduino.
5. 5. Write the basic code to control the state of the switch.
6. 6. Upload the code to the Arduino.
7. 7. Reactivate the power.
8. 8. Check the functionality.

Example code

void setup() {
  pinMode(2, INPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    Serial.println("Switch ON");
  } else {
    Serial.println("Switch OFF");
  }
}

Mini project

Build a control system for a lamp using the KCD3 switch and an Arduino.

Common mistakes

• Do not check the power supply before connecting the wires.
• Connect the switch to a power supply above 250V.
• Do not verify the code before uploading it to the Arduino.
• Omit checking the functionality.

Recommended accessories

• Arduino
• Connection wires
• Lamp
• 250V power supply

Frequently asked questions

Does this switch support remote control?
This switch is a direct contact switch and does not support remote control.

Which Arduino pins should I use?
Use a digital pin, such as D2, to connect the switch.

Can I use a different power supply than 250V?
Check the datasheet for the maximum supported power supply.

Does the switch support more than 15A?
Check the datasheet for the maximum supported current.
