ABSTRACT:
A two-in-one button structure includes a casing, a grounded plate, two signal plates, and two button bodies. The casing has two containing spaces and a plurality of guiding grooves respectively communicating with the two containing spaces. The grounded plate is contained in the two containing spaces. The two signal plates are separated from the grounded plate and are contained in the two containing spaces, respectively. The two button bodies are covering the two containing spaces, respectively. Each button body has a conductive element disposed on a bottom side thereof for allowing a conductive state to form between the grounded plate and a corresponding one of the two signal plates. Therefore, when one of the two button bodies is pressed, the grounded plate and the corresponding one of the two signal plates become conductive via the conductive element.
