Abstract: A keyboard including an elastomer dome keypad (15) and rocker mounted keys (25) positioned to acutate the domes (17) of the keypad (15) is disclosed. The rocker action keys (25) include outwardly extending flanges (29) that include apertures (49, 51) positioned to receive protrusions (33) that extend downwardly along the edge of the bezel apertures (23) in which each key (25) is to be positioned. The bezel (21) is positioned such that each key aperture (23) and, thus, each key (25) overlies the dome (17) of the elastomer dome keypad (15) that the key (25) is to actuate. The dome contacting region of the keys (25) is a pair of curved webs (53, 55). The curved webs apply a broad steady orthogonal force to the top of the underlying dome causing the dome to collapse in an even, positive manner even though the keys follow an arcuate path of travel.

Abstract: A process for the manufacture of a contact mat suitable for a keyboard or ypad is described. This contact mat is produced by the injection-moulding process and consists of a sheet-like composite body made of an electrically non-conductive two-component silicone rubber, and at least one carrier part, which is elastically deformable when pressure is applied to a key and is moulded out in the shape of a calotte. On the inside of the carrier part and in the pole region, there is a contact component which is made of an electrically highly conductive material. When the carrier part is depressed, an electrical connection is made via the contact component between the contact surfaces of a printed circuit located below the contact mat. In order to be able to manufacture the contact component in a simple manner and without waste, the contact component is made in an injection mould, wherein the entire lower mould part is at a temperature above the vulcanization temperature of the contact component. The upper cavity plate of the corresponding upper mould part consists of two halves of which one half is at a temperature below the vulcanization temperature. The contact component is produced by means of this half. Subsequently, a lower cavity plate of the lower mould part is rotated from this first into a second position, and the composite body and the carrier body are then moulded. This half of the upper cavity plate is at a temperature above the vulcanization temperature. Accordingly, all the curable components are vulcanized separately, even though they are moulded in the same mould.

Abstract: The present invention provides low cost electrical switch assemblies and methods for manufacturing same. The switch assembly comprises an array of resiliently flexible metallic conductors arranged in predetermined circuit pathways on a dielectric carrier panel. A plurality of apertures or cavities are provided at predetermined locations in the carrier panel. The switch contacts comprise a pair of generally L-shaped fingers which are integral extensions of the flexible conductors. The fingers extend from opposite edge surfaces of the carrier panel defining an associated aperture or cavity, to pass one another over or within their associated aperture or cavity, with the free ends of the fingers terminating adjacent one another. The free ends of the L-shaped fingers extend in part above or below the plane of the carrier panel, and are positioned in spaced relationship to one another so that the conductors they connect are normally open, but are sufficiently close to one another so that slight deflection of the fingers from their normal orientation moves the free ends in contact with each other to thereby close the switch. Alternatively, the free ends of the L-shaped fingers are positioned in contact with one another so that slight deflection of the fingers from their normal orientation breaks their contact. The metallic conductors and integral switch contacts may be formed by photoimaging and either chemical milling or additive techniques such as plating up or solder doming, and/or mechanical milling and/or precision die stamping techniques.

Abstract: A switching device comprises a flexible film of insulative material on which is printed a pictorial diagram or the like illustrating a plurality of controlled devices. A plurality of first conductive elements is arranged on a plane in contact with the illustration film and a plurality of second conductive elements is arranged on a second plane spaced from the first plane. In response to a pressure manually applied to the illustration film at a point corresponding to a desired controlled device, the first and second elements of the corresponding pair are brought into electrical contact to complete a circuit through a pair of terminals. Preferably, between each pair of corresponding first and second conductive elements is disposed an elastic element having resistance which varies from a non-conductive value to a conductive value in response to a pressure applied thereto.

Abstract: 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.
