Push-button switch and input device

Abstract

The present invention address the problem of providing a push-button switch which is capable of clearly displaying an image output from a display and which allows a person performing a depressing operation to have a distinct operational feel. Among the elements constituting the push-button switch, a button is a transparent or substantially transparent button which is disposed over a display and which receives a depressing operation. Lenses are disposed between the button and the display, and cause an image output from the display to be projected with a focal point at a diffusing plate in a top surface of the button in a standby position before a depressing operation is performed. A holding member incorporates the lenses in such a way that the position and orientation of each of the lenses are fixed with respect to the display. Thus, the problem is solved.
