The DFRobot Gravity Digital Push Button (Green) is a simple momentary switch with an on-board LED indicator, designed for the Gravity interface system. It features an immersion gold PCB surface, a bright green cap, and a standard 3-pin digital connector for plug-and-play use with Arduino and other microcontrollers.

A "D" marking on the board clearly identifies it as a digital sensor, and the wide 3.3–5 V operating range ensures compatibility with most development boards.
