    Abstract: A keyboard of a membrane contact type comprises a membrane contact unit having movable contacts, fixed contacts disposed respectively opposite to the movable contacts, and a printed wiring board having electronic circuit elements and provided with printed wiring lines. The membrane contact unit comprises a flexible, insulating, membranous substrate having movable contacts formed in a movable contact section and fixed contacts formed in a fixed contact section demarcated by a folding line, in the same surface as the movable contacts and arranged symmetrically about the folding line. First and second wiring lines connect the movable contacts and the fixed contacts respectively in a predetermined connecting pattern. A first terminal section having first terminals is connected respectively to the first wiring lines, and a second terminal section having second terminals is connected respectively to the second wiring lines. The first and second terminal sections are formed near the folding line. U-shaped slits are formed in the substrate so as to embrace the extremities of the first and second terminal sections, respectively, so that the first and second terminal sections project from the folded edge of the membranous substrate when the same is folded along the folding line to facilitate electrically and mechanically connecting the membrane contact unit to the printed wiring board.

    Abstract: Folded membrane switches (20, 50, 70) formed from foldable blanks (21, 51, 71) including two spaced contact-carrying panels (22,23) connected by an intermediate third panel (24). The blanks (21, 51, 71) are folded along the third panel (24) to position contacts (25, 27) on the contact-carrying panels (22,23) in alignment with one another, with a spacer layer (35, 61, 76) positioned therebetween to maintain the contacts (25, 27) in a normally separated or off condition. Part of the intermediate third panel (24) may be slit to define a tail (32, 58) or a tail (72) may extend from one of the contact-carrying panels (22, 23), the tail being used to connect the switch to external circuitry.

    Abstract: An accessory circuit component interconnected with the contacts of an electrical package comprises a flexible substrate with a circuit pattern of conductive traces thereon and a decoupling capacitor connected to selected conductive traces. A plurality of deflectable tabs inclusive of a portion of the substrate and a conductive trace are provided interiorly of side margins of the substrate. Upon assembly of the accessory component to a socket, the tabs deflect as urged by the contacts thereby providing openings through the substrate for receipt of the contacts therethrough. The conductive trace portions of the deflected tabs are connected to the contacts bearing thereagainst.
