  • Mode selecting switch for camera
    Patent number: 5815760
    Abstract: A switch for a camera includes a switch button. While being urged toward a flange section of a switch-button holding member by an urging member, the switch button is held so as to be movable in the pushing direction of the switch button and a direction perpendicular to the pushing direction. When one end of the switch button is pushed, the height to which the other end is raised can be lowered. Accordingly, the appearance of the camera is prevented from deteriorating. The switch is also advantageous in reducing the size of the camera.
