This compact illuminated push-button module combines a tactile switch with a built-in white LED indicator, making it handy for interactive electronics, prototypes and embedded control panels.
The switch outputs a digital HIGH/LOW signal and runs from +3.3-5V, so it suits common development boards including Arduino-compatible boards and micro:bit projects. It uses a self-locking toggle action: press once and the output switches HIGH while the LED turns on; press again and the output returns LOW while the LED turns off.
A PH2.0-3P connector supports simple Gravity-style plug-and-play wiring, helping keep classroom builds, robotics interfaces and project panels tidy. The pack includes 1 x Gravity: LED Switch and 1 x Digital Sensor Connector.
Features:
- Self-locking push-button mechanism with digital output
- Integrated LED indicator lights when the button is pressed
- Provides clear visual feedback for interactive electronics projects
- PH2.0-3P connector for easy plug-and-play wiring
- Available in multiple LED colors: red, yellow, green, blue, and white
Specifications:
- Operating Voltage: +3.3-5V (3.3V is recommended)
- Output: digital
- Connector: PH2.0-3P
- Dimension: 27×26.5mm
- Colors Available: red, yellow, green, blue, white
Use it as a clear on/off input for robotics control panels, backlit button interfaces, multimedia controls, event triggers and STEM demonstrations.
Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
