PURPOSE: A button device for electronics products is provided to integrate many buttons as compact size, and to operate the buttons with one button, to minimize an installation space for the buttons, thereby implementing product miniaturization. CONSTITUTION: A cellular phone body(100) is composed of upper and lower covers(110,120). A display(130) is formed on the upper cover(110), and a button insertion hole(140) is pierced in the middle of the display(130). The display(130) is star-shaped to display odd numbers in a maximumly projected part, displaying even numbers on angular points. The numbers are increased as a rotation direction of a watch. Buttons(200) are inserted into the button insertion hole(140), projecting a switch operation part in a lower part. A projector(270) is projected in accordance with the display(130). A switch operated by the switch operation part is installed to contact the switch operation part with a board fixed into the body(100). A guide part is installed to project an elastic part on a spinning side.
