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.Features:Internal LED turns On when the button is pressed downSpecifications:Operating Voltage: +3.3-5V (3.3V is recommended)Output: digitalConnector: PH2.0-3PDimension: 27×26.5mmColors Available: red, yellow, green, blue, whiteSuitable for interactive switch panels, illuminated keyboard prototypes, music player controls, recording triggers, educational electronics experiments and physical computing projects.
