A multidirectional input device is provided. A multidirectional input device includes a keytop capable of moving up and down through pressing. A membrane switch that has a plurality of switch elements and is arranged on the side that faces the reverse side of said key top. A plurality of domed switch operating assembly arranged above said plurality of switch elements are capable of switching on said switching elements. The plurality of switch operating assemblies are connected with strip-shaped joint portions to be integrated. Upon pressing the key top, at least one of said plurality of switch operating assemblies is pressed, and thereby at least one of said plurality of switch elements can be switched on.
The present invention relates to a multi-directional input unit. A thin plate-type operating member having an elastic force is fixed to any one of first and second keytops, and the first and second keytops are elastically urged to a predetermined height whereby a reliable click is generated. A portion of an outer peripheral portion of an operating member is mounted on a fixing plate, a first operating portion or a second operating portion is fixed to either the first or second keytops, the first and second keytops are elastically urged to a predetermined height from the fixing plate, and when either of the first and second keytop are pressed down, either of the dome-shaped first and second keytops are inverted, whereby a switch portion is operated.
A key structure comprises a membrane circuit, a substrate, a cover and a press element. The membrane circuit comprises at least one first signal generator and a second signal generator. The substrate is disposed below the membrane circuit to support the membrane circuit. The cover comprises a body and at least one protrusion, wherein the protrusion is disposed on the body corresponding to the first signal generator. The press element is disposed on the second signal generator, wherein when force is applied on the cover, the protrusion presses the first signal generator.
The compound operation input device of the invention includes a case; a flexible substrate mounted on a bottom plate section of the case a first operation body moving operable in a direction orthogonal to the flexible substrate a second operation body tilting operable and rotating operable, the second operation body being an annular member arranged at the periphery of the first operation body; a first switching means operated by the movement of the first operation body; a plurality of second switching means operated by the tilt of the second operation body; and a rotary switch that detects the rotating direction and the rotating amount of the second operation body. The first and second switching means and the slid contacting point pattern of the rotary switch are arranged on the same surface of the flexible substrate.
A push-on switch includes a movable contact which has a projecting segment permanently connected with an outer contact and which is accommodated in a recess of a switch enclosure. A sheet with a center through hole for the movable contact is placed on the switch enclosure. The push-on switch also includes a metal cover with a cover terminal. The metal cover is attached to the switch enclosure such that a pressing segment faces a disc segment of the movable contact corresponding to the position of the center through hole with a predetermined vertical gap between the pressing segment and the disc segment. When a very low and weak force is applied on the pressing segment, the pressing segment comes into contact with the disc segment to change the state of a first-stage switch.
