たことを特徴とするカメラの押釦スイッチ装置。A switch board, a conductive dome-shaped elastic plate disposed on the switch board, a first contact piece engaged with the switch board so as to be in constant pressure contact with the elastic board, and a first contact piece below the elastic board. A second contact piece that engages with the switch board so as to be positioned thereon, and a protrusion that fits into the switch board so as to be able to be pushed down and presses the elastic board approximately on the lower surface. a push button having a generally flat plate shape, and a push button support member disposed between the push button and the elastic plate and positioned relative to the switch board such that four elastic arms support the four corners of the lower surface of the push button; When the push button is pressed down, the elastic plate is elastically deformed downward by the protrusion and comes into contact with the second contact piece, whereby the first and second contacts are pressed through the elastic plate. A push button switch device for a camera, characterized in that the contact pieces are configured to be electrically connected to each other.
