Description

What is it? The red 2-position switch KCD4 is an electronic component used to control electrical circuits from a distance. With 4 pins, it allows switching between two states, making it ideal for electronics and Arduino projects. Features Colour: Red Positions: 2 Number of Pins: 4 Maximum Current: 16A 250Vac, 15A 125Vac SKU: ARD0014337 What is it used for? This switch is suitable for beginner and intermediate makers who want to control household devices or electronic projects. It can be used to create a two-position lighting system that turns on or off based on the position of the switch. Additionally, it can be connected to an LED or relay control module. Tutorial: How to use Red 2-position Switch KCD4 This red 2-position switch KCD4 is ideal for controlling electrical circuits from a distance by switching between two states. It is suitable for beginner and intermediate makers who want to control household devices or electronic projects. What you need Arduino Uno Connecting cable Connectors Steps Install the KCD4 switch on a mounting panel or plastic box. Connect the 4 pins of the switch to the control pins of the Arduino using connecting cables. Write an Arduino sketch to read the state of the switch and control a device. Check the correct functioning of the switch and the connected device. If necessary, adjust the connections to achieve the desired configuration. Example code const int interruptPin = 2; // Connect the control pin of the switch to this pin void setup() { pinMode(interruptPin, INPUT_PULLUP); } void loop() { int buttonState = digitalRead(interruptPin); if (buttonState == LOW) { // Action when the switch is in position 1 } else { // Action when the switch is in position 2 } } Mini-project Create a two-position lighting system that turns on or off based on the position of the switch. Connect an LED or relay control module to the switch. Common mistakes Connecting the switch to a potentiometer or another type of sensor. Not checking the state of the switch before writing the Arduino sketch. Using a switch not conforming to project specifications. Not having the necessary connectors for connection.
