Bistable Self-Locking Switch Button 12mm 12-24V Red / Green / Blue / Yellow

Description

What is a Bistable Self-Locking Switch Button? The bistable self-locking switch button, 12mm in size, is an electronic device designed to change the state of a circuit with just one touch. This type of button is ideal for projects requiring a switch that maintains its state even after being pressed. Features Dimensions: 12mm Operating Voltage: 12-24V Colour: Red, Green, Blue, Yellow Use Cases The bistable button is used in Arduino and ESP32 projects to control electronic devices that require a bistable switch. It’s particularly useful for creating alarm systems, access controls, and security devices. Tutorial How to use the Bistable Self-Locking Switch Button 12mm The bistable self-locking switch button 12mm is ideal for controlling electronic devices requiring a bistable switch. Useful for Arduino projects, access control, and security devices. What you need Arduino Uno Jumper Wires Breadboard Power Supply 12-24V Steps Connect the button to the breadboard. Connect an Arduino pin to the button. Connect another Arduino pin to ground. Write the Arduino sketch to read the state of the button. Verify that pressing the button changes the state of Arduino. Example Code void setup() { pinMode(2, INPUT); Serial.begin(9600); } void loop() { int val = digitalRead(2); Serial.println(val); } Mini Project Create a simple alarm system that turns on a light when the button is pressed and turns it off when pressed again. Common Mistakes Incorrectly connecting the button. Not verifying the state of the button. Using voltage outside 12-24V range. Failing to use an appropriate pull-up or pull-down resistor. Recommended Accessories 10kΩ Pull-Up Resistor RGB LED Buzzer Relay 5V Frequently Asked Questions What is the operating voltage? Check the datasheet. Why doesn’t the button change state? Check connections and sketch. Can it be used with other microcontrollers? Yes, but verify input voltage.
