| 43 | Dome sheet unit and membrane switch having the same | US12588032 | 2009-10-01 | US20100126841A1 | 2010-05-27 | Tsuyoshi Inoue; Shintaro Ogura; Katsutoshi Shinagawa |
| A membrane switch can attach an elastically deformable dome to a board in a reliable manner such that the dome is not detached even if a fixing sheet is made thinner and smaller and therefore has a smaller footprint. This switch has: a dome (110) that is formed projecting toward the surface and that is dented opposite toward the back surface by elastic deformation; and a flexible fixing sheet (120) that has a back surface of an adhesive face pasted to the entire face of the surface of the dome (110). The fixing sheet (120) fixes the dome (110) in a predetermined position of a board (4) by means of a stretching part (122) which stretches radially outer to the dome (110), from an outer rim (112) of the dome (110), in a direction virtually orthogonal to a direction in which the dome (110) projects. A plurality of slits (130) formed in the fixing sheet (120) at predetermined intervals along the outer rim (112) of the dome (110), prevent a stretching part (122) of the fixing sheet (120), from joining with a dome covering part (121) which is a portion above the dome (110) that continues in the radial direction of the dome (110). | ||||||

| A pressure sensor includes a surface sheet whose front side is an operating surface and a substrate sheet that includes a plurality of switches and that is disposed below the back side of the surface sheet at a predetermined space therebetween. When the operating surface is depressed, the surface sheet is deformed toward the substrate sheet and a switch of the plurality of switches is turned into an input state, and a resolution of a switch signal from each of the switches varies in accordance with the amount of a pressing force applied on the operating surface. Therefore, an electronic device, such as a cellular phone, installed with the pressure sensor can have various functions realized by a variation in the resolution. | ||||||

| 60 | Laminated membrane switch | US118410 | 1980-02-04 | US4314114A | 1982-02-02 | Willis A. Larson |
| An assembly for manufacture of a membrane switch includes a composite formed of first and second layers, one substantially thicker than the other, with the composite having a size and shape to form both outer members of a membrane switch when folded back upon itself. Metallic conductors, preferably silver, are formed on the composite prior to folding. A spacer member having spaced openings therein and extending over approximately half of the area of the composite is positioned thereupon. After the composite is folded over the spacer member, laminating heat and pressure are applied to the assembly with the result that a bond is formed between the spacer member and composite and between the layers of the composite. | ||||||
