Tactile Push Button

This tactile push button module is a compact and reliable momentary switch designed for use with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms. It features a 4-pin interface with a built-in pull-down resistor, making it ideal for detecting user input via digital pins with minimal wiring.

The button closes the circuit only when pressed, making it perfect for implementing user interactions like menu navigation, device control, counters, or triggering actions in code.

Specifications:

• Operating Voltage: 3.3V to 5V

• Button Type: Momentary (normally open)

• Pinout: VCC, GND, OUT, NC

• Built-in Resistor: Yes (pull-down)

• Switch Life: >100,000 cycles

• Output: Digital HIGH when pressed

• Mounting: Breadboard or PCB-compatible

• Size: Approx. 18mm × 13mm

Applications:

• Arduino and microcontroller input

• DIY electronics and smart devices

• User interface elements (start/stop, reset, select)

• Educational kits and prototyping

• Game controllers and embedded control panels

This tactile button module is a simple, reliable, and essential input device for any interactive microcontroller project.
