| 221 | Electronic calculator assembly | US899622 | 1978-04-24 | US4197586A | 1980-04-08 | Charles A. Nidiffer |
| An electronic calculator assembly is disclosed having a flexible printed circuit board bonded to a layer of resilient material mounted on a rigid backing plate. An integrated circuit package containing electronic calculator circuitry is held tightly against the flexible printed circuit board by a cradle assembly. Leads from the integrated circuit package make contact areas on the flexible printed circuit board and depress the flexible printed circuit board into the resilient layer. A keyboard assembly is mounted to the opposite side of the rigid member and the flexible printed circuit board is folded around the rigid member so that contact areas on the flexible printed circuit board also form fixed switch contacts for the keyboard. | ||||||

| Electric switches are described in which a resilient, electrically conductive, elastomeric member is spaced adjacent but apart from contact means; among features are the elastomeric connector: of sheet form; on metal contacts as a movable contact bridge; defining a simple and durable multiple switch array including a keyboard, a digital coding assembly and a detector; and as the means, especially with proper selection of distributed conductive particles in the elastomer for limited conductivity, of eliminating the electrical effects of bounce in solid state electronic logic circuitry and the like. Fabrication of the switch as a simple, thin compact laminate using printed circuit boards is shown using the preferred silicone elastomer and carbon filler. In preferred embodiments pressure against conductive elastomer sheet means will cause it to connect to a contact element conductively and release of pressure will cause the sheet means to disconnect. The sheet means can be used as a floating connection for one or more circuit elements, and in this form has particular application in a keyboard assembly, particularly in connection with replaceable printed circuit boards and in digital coding techniques with a single printed circuit board. Preferably, the sheet means resiliently, reversibly deforms from first to second conditions, typically engaging the contacts in the deformed or bulged condition. Preferably in one condition the sheet means takes a planar form, positioned by a spacer layer from the contacts. And preferably the contacts are elements of a printed circuit.
