DFRobot Gravity LED Self-Locking Switch - Yellow

This illuminated latching push button combines a tactile switch with a built-in yellow indicator LED, making it easy to add clear on/off control to interactive electronics and educational prototypes.

When the button is pressed down, the module self-locks, outputs High and lights the LED. Pressing it again releases the latch, outputs Low and turns the LED off, giving simple visual feedback for panels, interfaces and debugging.

It provides a straightforward digital output for Arduino, micro:bit and other small embedded boards, and supports common 3.3–5V logic systems. The Gravity-style PH2.0 3-pin connector helps keep wiring quick for classroom builds and maker projects.

Included in the pack are 1 x Gravity: LED Switch and 1 x Digital Sensor Connector.
