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.

The rolling member receives a pressing force toward a position where the distance between the facing faces of one face of the track member and the inner face of the clamper main body is narrow, so that a frictional force based on the taper shape acts on the rolling member, and the restraint of the clamper main body with respect to the track member is performed. Further, a frictional force based upon the taper shape is released and the non-restraint of the clamper is performed.

Abstract: A push-button switch has a sound function and a button accepts a pushing operation. A second plunger slides in coordination with the pushing operation on the button. A torsion coil spring stores or releases elastic energy together with sliding of the second plunger. A sounder unit slides using elastic energy released by the torsion coil spring at the same time as the torsion coil spring elastically deforms, and the sounder unit generates a hitting sound by impacting a hitting piece. A movable contact piece has a movable-side contact Pm and is capable of moving due to being pushed by the sliding sounder unit. A fixed contact piece has a fixed side contact, the movable-side contact Pm being engaged with the fixed side contact at the same time or substantially at the same time as the sounder unit hits the hitting piece.
