Key Switch Sensor Module (Black Color - Arduino Compatible)

The Key Switch Sensor Module (reference SENJANMODKEY, commonly known as KY-004) is a digital input component designed for Arduino, Raspberry Pi, and ESP32 platforms. It features a FZ1713 tactile push button, a 10kΩ pull-up resistor, and three male header pins for straightforward integration. The module closes the circuit and outputs a HIGH signal when the button is pressed, operating within a voltage range of 3.3V to 5V. With compact dimensions of 18.5mm x 15mm and a durability of 100,000 cycles, it is ideal for projects requiring simple and reliable user interaction.
