Claims

[Scope of utility model registration request]

A fixed contact is provided at an appropriate position on the front surface of the printed circuit board, and an elastic plate-like body is arranged along the front surface of the printed circuit board, and a movable contact is provided at a position corresponding to the fixed contact on the rear surface of this elastic plate-like body, and a cup-shaped structure is provided around the fixed contact. The movable contact and the fixed contact are separated as legs, and a push button whose rear surface abuts the front surface of the elastic plate at a position in front of the movable contact is inserted through a hole drilled in a panel disposed in front of the elastic plate. The panel is arranged such that its front surface protrudes from the outside of the front side of the panel so that it can be operated by pressing, and the movable contact comes into contact with the fixed contact when the push button is pressed, and the panel is made of a translucent material. At the same time, a light-shielding layer is formed on the front surface of the area excluding the display area for characters, symbols, etc. to form a cut-out character-shaped display area, and a light guide plate insertion hole is formed in the printed circuit board to form a light guide plate. A light guide plate having a light entrance portion on the rear surface side of the printed circuit board through the insertion hole is arranged to double as the panel or to be formed separately and overlapped with the rear surface of the panel, and the outer periphery of the elastic plate-like body is A push-button switch, characterized in that a light source is disposed so as to fit into a falling wall that falls from at least one of the panel, the light guide plate, and a case surrounding the panel, and to allow light to enter the light guide plate light input portion.
