A switch integrated type housing includes a housing body, a switch button sheet, a conductor and a cover sheet. The housing body is provided with a plurality of concave sections on an outer surface of the housing body. The switch button sheet is provided on the outer surface to cover the plurality of concave sections. The conductor has a dome shape downwardly projecting and is provided in each of the plurality of concave sections to contact the switch button sheet. The cover sheet is provided between the switch button sheet and the outer surface of the housing body in a portion of the outer surface of the housing body other than the plurality of concave sections and to cover a lower surface of the conductor in each of the plurality of concave sections.

Switch integrated casing and electronic equipment having the casing

A luminous switch using an inorganic EL material is provided with a plurality of switch sections so as to reduce acoustic noise. The switch sections are provided with a plurality of protruding parts () and a plurality of supporting sections () formed on a surface of a structure (); an elastic deformable conductor () arranged to have a convex surface opposed the protruding parts (); a wiring sheet (A) for covering the conductor (); a luminous sheet () for covering the wiring sheet (A); and a plurality of switch buttons () arranged above the luminous sheet (). The luminous switch has a structure in which at least two supporting sections () are arranged around the protruding parts (), and a space () is formed between the protruding parts () and a switch sheet (). The conductor () is accommodated in the space (). In a case main body (), an electronic component () is mounted and a substrate () provided with wiring is arranged. The switch buttons () are fixed on a key sheet (). A top plate () is arranged on the key sheet () by surrounding the switch buttons (). The top plate () is arranged to cover lower components.

Luminous switch and electronic device provided with the same

A switch according to the present invention has a plurality of protruding parts and a plurality of support sections both of which are formed on a surface of a thin metal sheet by press molding. The switch includes a plurality of switch sections formed by elastic deformable conductors arranged so as to have a convex surface opposed to the protruding parts, a wiring sheet covering the conductors, and switch buttons. At least one support portion is provided around the protruding parts and a gap area is left between the protruding parts and a switch sheet. In this gap area, each conductor is accommodated at the same position as the protruding parts. The support sections are disposed in a dotted-form to accomplish improvement of a feeling of click that is one of the performances on which the user places much value. In addition, a casing, the protruding parts, and the support portions are press-molded of a thin metal sheet, thereby obtaining the effect of reducing wall thickness and increasing the rigidity.
