Tutorial: How to use T85 KCD1-B3

The T85 KCD1-B3 is a DPDT panel switch used to control two independent circuits. Useful for projects that require a double position switch.

What you need

• T85 KCD1-B3
• Arduino or microcontroller
• Connection wire
• Resistor (optional)

Steps

1. 1. Check that the switch is compatible with the supply voltage (220V AC).
2. 2. Prepare the connection wires for the 6 pins of the switch.
3. 3. Connect the wires to the respective pins of the switch: 1-2, 3-4, 5-6.
4. 4. Connect the microcontroller to a pin of the switch (e.g., pin 3).
5. 5. Write the code to control the state of the switch.
6. 6. Test the switch to ensure it works correctly.
7. 7. Install the switch in a panel.
8. 8. Verify the stability of the contact.

Example code

```
int switchPin = 3;
void setup() {
  pinMode(switchPin, INPUT);
}
void loop() {
  if (digitalRead(switchPin) == HIGH) {
    Serial.println("Switch ON");
  } else {
    Serial.println("Switch OFF");
  }
}
```

Mini project

Create a simple lighting circuit with two lights controlled by the T85 KCD1-B3. Connect two LEDs to the outputs of the switch and check the state with an Arduino.

Common mistakes

• Do not verify voltage compatibility before installation.
• Incorrectly connect the wires to the pins of the switch.
• Omit the verification of the switch contact.
• Do not use a resistor as pull-up or pull-down.
