| 21 | Method of producing an electric or electronic component, a method of producing a key and a key | US615306 | 1990-11-19 | US5199557A | 1993-04-06 | Gert Brandt; Soren R. Hansen |
| In a process of producing an electric or electronic component, particularly a key, a continuous track of a metal foil is machined into two metallic terminal components constituting links between two carrier strips. A base housing component is cast from a high temperature resistant material around the terminals and is connected to the carrier strips through two tags protruding outwards from opposite, outer side surfaces of the base housing component. In an inner recess of the base housing component a domed metal disc having an acoustically damping coating on the convex side surface thereof, an elastically compressible rubber component and a push button are arranged. On top of the base housing component, a top housing component preferably made from the same high temperature resistant plastics material is arranged. Within the recess of the base housing component, the terminals define electric contacts with which the domed metal disc cooperates. The terminals are separated from the carrier strips and bent into the configuration of pins of an electronic key, and the key is still connected through the tags to the carrier strips transferred to a test stand, in which the key is tested. Provided the key is identified as a properly functioning key, the tags are separated from the base housing component. | ||||||

| A dual tactile feedback, three-state, low profile pushbutton switch comprising an insulated housing, a metal dome, an extended travel molded elastomeric dome or stem having a conductive material on a bottom surface for contacting the metal dome and contacts in the switch housing, a collar having an opening for a top portion of said elastomeric dome to protrude therethrough, and a fixed contact under the metal dome on the base of the insulated housing connected to a switch terminal. A flat plate with four legs is placed above the stem which moves adjacent to the walls of the housing. The plate extends through a frame and openings on the sides of the frame snap on to the sides of the insulated housing. Greater switch reliability is achieved by having the elastomeric dome with a bottom portion comprising a conductive material for contacting the metal dome. An alternate embodiment of the three-state switch comprises a pushbutton disposed above an upper, extruded, elastomeric element for lower cost advantages having conductive material on a bottom surface for making electrical contact within the base of the switch housing and a lower metal dome, when the pushbutton is activated. The lower metal dome also makes electrical contact with contacts in the base of the switch housing. | ||||||
| 39 | Thin profile keypad with integrated LEDs | US112178 | 1998-07-08 | US5960942A | 1999-10-05 | Curtis W. Thornton |
| A backlit keypad assembly includes a flexible film having a bottom surface having electrical circuits, typically referred to as flex circuits, thereon and a top surface having at least one, and preferably a plurality of keys defined thereon. Each backlit key includes a cavity on the underside thereof. In each cavity is a light emitting diode, preferably of bottom emitting type, attached to the flexible film and connected to the electrical circuits and a filler material which at least partially surrounds the light emitting diode. Associated with each key is a push-type switch below and in respective aligned relationship with the light emitting diodes which senses when the corresponding key is pressed down by a user. The light emitting diodes emit light directly through the flexible film without intervening layers such as light guides, thereby allowing the overall lighted keypad assembly to be thinner than with previous approaches. Such a keypad may be fabricated by directly attaching a plurality of bottom emitting light emitting diodes to the bottom side of the flexible film and connecting the light emitting diodes to the electrical circuits. Thereafter, the flexible film is vacuum formed so as to form a plurality of depressible keys on the top surface thereof and a corresponding plurality of cavities on the bottom surface thereof containing therein the light emitting diodes. The process continues by thereafter substantially filling the remainder of the cavities with a filler material which hardens upon curing and adheres to the bottom surface of the flexible film so as to form a flexible pad. The flexible pad is then typically placed in intimate contact with the printed circuit board and preferably mated thereto. | ||||||

| A pushbutton switch having a frustoconical switch cap of plastic, which acts as a restoring element, is proposed, which switch cap permits a very exact switching operation in comparison with known switch caps of rubber or silicone. In order to achieve optimum switching characteristics with defined switching displacements and forces, a thermoplastic elastomer is used which, as a block copolymer, has special properties regarding the flexibility of the switch cap. In this case, the material selection and dimensions of the switch cap determine the special properties of the pushbutton switch. | ||||||
