Abstract
A button assembly comprises a cylindrical key top () loosely inserted into a hole () formed on a casing (). The upper surface of the key top () is a pressed face (). The assembly further comprises a deformation member () disposed below the key top () in the pressing direction. The deformation member () deforms to produce repulsive force when the key top () is pressed down. The assembly further comprises a conductive member () attached on the bottom of the deformation member (), and switch contacts () which come into contact with the conductive member () and become conductive by the deformation of the deformation member (). The central axis of the key top () and the central axis of the conductive member () are separated with certain spacing. The key top () has a hang-over member extending from the lower end of said key top over the central axis of the conductive member (). The hang-over member () moves to the pressing direction with the key top () when the key top is pressed down, and the bottom of the hang-over member () presses the deformation member () in the pressing direction.
