    Abstract: Disclosed is a data entry keyboard which has a multitude of depressible keys which are selectively depressed for the entry of predetermined data. In the keyboard, an insulating member is sandwiched between a first substrate having stationary electrodes and a flexible second substrate having movable electrodes. The stationary and movable electrodes face one another through apertures formed in the insulating member. Upper and lower marginal surface portions of the insulating member, including the respective peripheral edges of the apertures, are kept parallel to the first and second substrates corresponding thereto by a plurality of protuberances on the substrates so that voids with a predetermined width are left between the marginal surface portions and the individual substrates. The movable electrodes of the second substrate are electrically fixed, in the form of a cantilever each, to the extreme end portions of branch conductor strips which diverge from a main conductor strip at right angles thereto. When one of the keys is depressed, the second substrate is deformed to narrow the corresponding void, thus bringing the corresponding movable and stationary electrodes into contact with each other.

    Abstract: A pressure-sensitive element for use in a keyboard switch etc., comprising a conductive porous material which is rugged, an elastic insulator which bulges more than convex parts of the conductive porous material without covering the convex parts, and a conductive layer which opposes to the conductive porous material through the elastic insulator. When no pressure is applied, openings are formed between the convex parts of the conductive porous material and the conductive layer through the elastic insulator, whereby the pressure-sensitive element is in its nonconductive state. When a pressure is applied, the elastic insulator is deformed to bring the convex part of the conductive porous material into contact with the conductive layer, whereby the pressure-sensitive element is brought into its conductive state.

    Abstract: A keyboard for a musical instrument having a plurality of elongated keys with each key having a rearwardly extending actuating arm. The arm has an upper and a lower nonresilient switch actuator for actuating a respective first and second keyboard switch with each switch having a substrate with at least one fixed contact. A deformable membrane has coupled thereto a movable contact which is adapted for movement into and out of electrical connection with the fixed contact. The first and second switches are positioned so that the lower actuator normally maintains closed the first switch and when the key is actuated the first switch opens and the upper actuator closes the second switch. The deformable membrane is formed of Poron cellular urethane which distributes and absorbs the actuation force and springs back to its undeformed shape when not actuated.

    Abstract: A method of forming a switching device having a movable contact that is an integral part of a metallic support substrate and is supported above the support substrate by a plurality of spring-like legs that are also an integral part of the support substrate. One or more of the switching devices is produced by forming one or more groups of curved, unconnected radially extending slots in a metallic substrate to define support legs, plastically deforming the legs defined by the slots past their elastic limit, and then precipitation hardening the complete structure. The slots can be formed by a photomasking technique followed by an acid etch with the etch being performed from both sides of the metallic support substrate. To provide a desired tactile response characteristic, and to assure movement of a central portion of the switching device past the plane of the metallic support substrate, a portion of each of the legs defined by the slots may be removed to thin that portion of each leg. The plastic deformation may be performed in a male-female die mechanism.

    Abstract: A keyboard switch device comprising rows and columns of intersecting wires conductors held taut and normally spaced slightly from each other by a separator sheet of non-conducting material having openings therein aligned with the intersections of at least certain of the conductors. The conductors are engaged by depressing different keys aligned with the conductor intersections and a relatively thick layer of soft elastomeric materialis interposed between the keys and conductors to normally hold the keys in raised position and to transmit pressure from the keys to engage the conductors. By merely changing the sizes, shapes and positions of the openings, the switching device can be made to produce different output coded signals. Also, by changing the configuration of the various rows and columns of conductors different switch matrix patterns can be produced.
