    摘要: An operator manipulating means for a programable electronically controlled sewing machine. The operator manipulating means provides an array of switch points, each related in a row, to discrete needle positions attainable by the electronically controlled sewing machine; and in a column, to the least feed increment attainable thereby. The switch array is fabricated using a pair of printed circuits, one of which must be flexible and each having spaced, parallel conductors, and arranged with respect to each other so that the conductors of one are substantially perpendicular to the conductors of the other and are in facing relationship. The printed circuits are separated in a first embodiment by a pair of insulating sheets, each having an array of apertures in spaced registry with each other and aligned in rows and columns with the conductors on the printed circuits. The pair of insulating sheets are separated by a flexible conducting sheets which may be used as a common conductor. Depression of a conductor on the flexible printed circuit through an aperture of an insulating sheet will establish a connection to the flexible conducting sheet, which conducting sheet will be deflected through the aperture in spaced registry to establish a connection with a conductor of the other printed circuit.

    摘要: An assemblage of hand-operated switches includes a plurality of printed fixed contact sets on an insulating base. A spacer sheet overlying the insulating base has openings therein in register with the fixed contact sets. Further overlying the spacer sheet is a plastic film having printed movable contacts formed thereon in register with the spacer sheet openings. Each switch is equipped with a key or button, upon depression of which the corresponding movable contact is moved into engagement with the corresponding fixed contact set through the corresponding spacer sheet opening. The plastic film together with the printed movable contacts thereon can be replaced by a single piece of resilient sheet metal.

    摘要: Encoded keyboard switch comprises a single sheet of flexible film which has switch electrodes and circuit conductors applied to one surface. The sheet of film is folded to form four sections. After folding, the switch electrodes of the two upper sections are opposed to each other and the electrodes of the remaining two sections are opposed to each other so that when the folded film is pressed at a switch site, the two switches formed by the opposed electrodes are sequentially closed. The switch electrodes are interconnected in accordance with an improved encoding scheme which results in a reduced requirement in the number of circuit conductors, the elimination of some switch electrodes, and other advantages.
