| 189 | Method of forming a deformed, integral switching device | US508486 | 1974-09-23 | US3950846A | 1976-04-20 | Wendell C. Johnson |
| 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. | ||||||

| A keyboard switch assembly including a printed circuit board having four switch terminals on one side of the board, three of the terminals being arranged in a triangle and the fourth disposed within the triangle. Conductors on the one side of the board are respectively joined to the interior terminal and at least one of the three terminals.

The switch element has a fourth protection formed from the interior of the dome adjacent the center thereof which is in registry with the interior terminal and engages that terminal when the dome is deflected thereby completing an electrical circuit between the three terminals and the interior terminal. A layer of insulating material covers the conductors exclusive of the terminals. A sheet of insulating material covers the insulating layer and has an opening therein which receives and locates the switch member. Another sheet of insulating material covers the first sheet and the switch member. A plate covers the second insulating sheet and has an opening therein which receives a push button in registry with the switch element, depression of the push button actuating the dome of the switch member to a nonovercenter, deflected position in which the interior projection on the dome engages the interior switch terminal.

| A mechanically operated keyboard with key stations having a multiplicity of electrical switch contacts for providing an encoded electrical data output signal corresponding to and uniquely identifying individual key stations includes an array of movable contacts each corresponding to an individual key station and which are formed in a sheet of conducting material mounted above a corresponding array of fixed contacts to form multiple contact electrical switches for each key station of the keyboard. Each movable contact has a central member suspended to the sheet of conducting material in cantilevered fashion and includes a plurality of peripherally spaced contact fingers joined to the central member such that the contact fingers adjacent the junction of the central member to the conducting sheet will contact associated fixed contacts of a key station only after the remaining contact fingers have come into contact with their associated fixed contacts. An electrical circuit coupled to the contact fingers provides a strobe output signal only when all of the electrical switch contacts associated with a given key station have been actuated as indicated by the closure between the contact finger adjacent the junction of the central member to the conducting sheet and its associated fixed contact.
