| 摘要 | A switch having a transparent area and suitable for placing over a video display without obscuring the information displayed beneath the switch. The switch comprises an elastically bendable conducting strip which, when a top transparent member of the switch is pushed, is forced into contact with a conducting area on the top transparent member. The natural elasticity in the bendable strip serves to break the contact between the conducting area and the bendable strip when the switch is released. | ||||||
| 权利要求 | 1. A manually operable switch for surface attachment and having at least one transparent area covering but not obscuring visual information displayed on a display area of the surface beneath the switch, comprising: a. an elastically bendable conducting strip having a shape not obscuring information in the display area when placed in a preferred position near the display area, and having display and viewer sides; b. a plurality of attachment standoffs attached at spaced intervals to the display side of the bendable conducting strip; c. a plurality of insulating standoffs, each attached on the viewer side of the bendable conducting strip between the attachment points of the plurality of attachment; and d. an actuating member having a conductive area and at least one transparent viewing area and attached to the insulating standoffs in a position i. allowing relative movement of the actuating member toward the plurality of attachment standoffs causing elastic bending of the bendable conducting strip and electrical contact between it and the conductive area, and ii. causing the display area to be at least partly covered by the viewing area when the bendable conducting strip is in its preferred position near the display area. 2. The apparatus of claim 1 wherein the bendable conducting strip comprises a metal strip having an open area. 3. The apparatus of claim 1 wherein the bendable conducting strip comprises a first U-shaped conductive strip suitable for at least partially surrounding the display area. 4. The apparatus of claim 3 wherein the actuating member comprises a transparent strip and a second U-shaped conductive strip having substantially the dimensions of the first U-shaped conductive strip, and attached to the actuating member. 5. The apparatus of claim 4 including an adhesive coating for attaching the Second U-shaped conductive strip to the actuating member. 6. The apparatus of claim 3 wherein the actuating member comprises a transparent strip having a viewing area larger than the display area dimensions, and a second U-shaped conductive strip having substantially the dimensions of the first U-shaped conductive strip and attached to the periphery of the transparent strip. 7. The apparatus of claim 3 wherein each insulating standoff comprises an insulating shim having a width no greater than the width of an arm of the U-shaped conductive strip, a length small compared to the interval between successive insulating standoff attachment points and a thickness smaller than that of the plurality of attachment standoffs. 8. The apparatus of claim 1 wherein the bendable conducting strip is formed from a beryllium copper alloy. 9. The apparatus of claim 1 including adhesive coatings for attaching the standoffs to the respective surfaces of the actuating member, bendable conducting strips, and surface. 10. The apparatus of claim 1 wherein the actuating member comprises a transparent member and a pair of conductive strips attached along the edge of the transparent area of the transparent member. 11. The apparatus of claim 1 wherein the conductive area and the bendable conducting strip both have gold coatings at points where they contact each other upon actuation of the switch. 12. The switch of claim 1 wherein said plurality of attachment standoffs are spaced from each other and said insulating standoffs are also spaced from each other but arranged in interlacing relation to the plurality of attachment standoffs whereby said bendable conducting strip is flexed between adjacent attachment standoffs by said insulating standoffs upon closing said switch. 13. The apparatus of claim 1 wherein the bendable conducting strip comprises a first I-shaped conductive strip and the conductive area comprises a second I-shaped conductive strip attached lengthwise to one face of the actuating member. |
