KY-004 Push Button Tactile Micro Switch Module

The KY-004 Push Button Tactile Switch Module is an essential component for any electronics enthusiast, providing a simple and reliable way to input digital signals into your microcontroller. Featuring a high-quality momentary micro switch, it registers physical presses and translates them into actionable data, perfect for building user interfaces, reset switches, or menu navigation panels in your DIY projects.

Widely used in DIY IoT projects, custom keypads, and robotic control systems, this module is fully compatible with popular platforms like Arduino, Raspberry Pi, and ESP32. Its standard 3-pin interface allows for quick breadboard prototyping, while the onboard circuitry ensures seamless integration into your custom circuit diagram without the need for complex external wiring.

Features:

• Momentary Action: Registers a clean digital high or low signal immediately upon button press.
• Broad Compatibility: Safely operates with both 3.3V and 5V logic systems.
• Onboard Resistor: Features an integrated 10k SMD resistor (103) for stable pull-up configurations.
• Breadboard Friendly: Utilizes a standard 2.54mm pitch 3-pin header for easy connection and testing.
• Compact Size: A minimal footprint makes it ideal for space-constrained electronics and maker projects.
