An example portable electronic device includes a front glass cover; a rear cover; a bezel surrounding a space defined by the front cover and the rear cover, the bezel including a portion including an opening; a display device built in the space; and a plate including a plane parallel to the front cover within the space. The example electronic device includes a key movably inserted in the opening; a support structure mounted on the plate or a portion of the bezel and including a hole through which the key passes; a dome button mounted on the support structure and arranged to face the first surface of the key and the hole so that the key can be pressed; and a waterproof structure including a flexible material.

A dome-actuator structure for use in a dome switch is disclosed. The dome-actuator structure comprises a lower substantially horizontal lower dome, an upper actuator portion attached to the lower dome and that is positioned vertically over the lower dome such that depressing of the actuator portion operates to depress the lower dome, and a lateral arm that couples the actuator portion to the lower dome. The lateral arm and the lower dome are formed from a common piece of material. The actuator portion comprises an actuation block, made of plastic or synthetic material or made of natural or synthetic elastomer, fixed to the lateral arm.

A movable contact includes a conductive member having an outer end having substantially a rectangular shape when viewed from above the conductive member. The conductive member includes a dome portion, a flange extending in a direction away from the dome portion, a connection portions provided at each of four corners of the rectangular shape, and a contact portion extending away from the flange. The connection portion, a first boundary portion where the connection portion is connected to the flange, and a second boundary portion where the connection portion is connected to the contact portion may constitute a drawn portion. Alternatively, the first and second boundary portions may be curved to be concave toward the dome portion.

A push switch includes a case having a containable portion defined by a bottom plate and a wall portion, a central contact provided on the bottom plate, an outer contact provided on the bottom plate so as to be spaced from the central contact in the containable portion, a movable contact disposed above the central contact and the outer contact, a cover film disposed so as to cover the containable portion, and a disc-shaped pressing member provided between the movable contact and the cover film. By pressing the pressing member downward, the movable contact is displaced from a first position to a second position. A diameter R of the pressing member is in the range of 30 to 45% of the width in the longer side direction of the movable contact and in the range of 45 to 60% of the width in the shorter side direction of the movable contact in a plan view.

A push switch including a pressing member, a movable contact, an interposed member, a first fixed contact, and a second fixed contact is provided. The pressing member includes a pressing portion configured to be pressed, and includes an elastically deformable peripheral wall portion having a lower end portion and extending downward and outward from the outer periphery of the pressing portion. The movable contact has a dome shape and is disposed below the pressing member. The interposed member is disposed between the pressing member and the movable contact, and is configured to press the movable contact by receiving and being pressed by the lower end portion of the peripheral wall portion of the pressing member. The lower end portion of the peripheral wall portion of the pressing member presses the interposed member while the peripheral wall portion is subjected to elastic deformation in response to the pressing portion being pressed.
