A keyboard comprising at least one flap forming a key, the flap being pressed against a contact point when depressed from above, and rising back after the depressing. The flap is attached by its one end to the frame sheet of the keyboard in such a way that this structure forms the hinge of the key. There is at least one buckling member in connection with the flap, and the flap is formed rigid. The keyboard may be formed in such a way, for example, that a keyboard frame sheet is formed, the flap forming the key is cut partially off the keyboard frame sheet, a buckling member is formed in connection with the flap, and the flap is lifted upwards from the surface of the frame sheet.

There is disclosed a click disc switch assembly comprising a plate-like base having on it electroconductive ink paths including (a) "row" paths each including a respective row of contact pads in a row-and-column matrix of such pads on the base, and (b) "column" paths corresponding to the columns of the matrix and including respective junction pads. Overlying the columns of the matrix are click disc strips secured to the rest of the assembly solely by being adhered to an overlying sheet sealing the top of the assembly. Interposed between the strips and the "row" paths is an insulating layer deposited on the base to cover portions of the row paths while leaving uncovered their junction pads. Each click disc is electrically coupled to the corresponding "column" path on the base by the coming into contact of the disc when depressed to branch segments of a further electroconductive ink path (one for each click disc strip) deposited on the insulate layer and attached through an aperture therein to the junction pad of that "column" path. Variations in the thickness of the paths on the base and on the layer are cancelled out by depositing on the base, below the click discs, pairs of bars of the same thickness as the lead portions of the paths on the base, and by raising the contact pads by an amount equal to the thickness of the paths on the layer. The base is a laminar member comprising an overlying flexible plastic sheet adhered to an underlying stiffening board. The assembly may include a tail for connecting it to other circuitry.
摘要:
A switch mechanism useful in a calculator type keyboard includes a printed circuit board conductor in which is punched a crater-like depression with a raised edge portion and a dome-like member positioned so that its apex may contact the raised edge portion when the switch mechanism is depressed. The punched crater-like depression is specifically formed by striking the printed circuit board conductor to form an edge extending above the predetermined height of the conductor surface, which in turn, is disposed above the planar surface of the dielectric substrate.
