| A keyboard assembly for a mobile device is provided that reduces the separation between keys by reducing the number of required dome switches. A reduction in the number of dome switches can alternatively reduce the amount of real estate taken up by dome switches on a printed circuit board (PCB). Fewer dome switches than keys are provided on a PCB to activate a desired functionality when a key is depressed. The dome switches are each actuatable by and disposed between more than one key, such keys preferably being adjacent keys. Each key has an actuator with at least one arm for actuating a dome switch in an actuated dome switch pattern when the key is depressed. Such a keyboard assembly can be used for any electronic device having a standard QWERTY or Dvorak keyboard layout, a standard telephone or numeric keypad layout, or any other layout of keys. | ||||||

A first part of the printed circuit contains a plurality of conductors, and a second part contains a plurality of resistor strips for supplying voltage levels to each conductor. In order to connect the first and second parts without crossings, a grid of connection strips is provided between the conductor strips and resistor strips and connected thereto. The film is bent along a score line extending through the grid and at a right angle thereto, with the conductor strips and resistor strips located on the outside of the folded film. The film is then clamped to the terminal device at the score line so that each connection strip is clamped on both sides of the score line. | ||||||

| 34 | Encoded keyboard switch | US502369 | 1983-06-08 | US4450324A | 1984-05-22 | Kazutoyo Fukukura; Richard A. Martinez |
| 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. | ||||||

| A printed circuit keyboard assembly is disclosed comprising a waterproof jacket portion which includes a cover member overlying a sheet of raised key-tip portions, the jacket portion being releasably mounted to a position adjacent the waterproof switch matrix portion. Depression of a key-tip portion will result in the deflection of the switch matrix portion thereby generating binary coded signals representing the key-tip portion depressed. The cover member secured to the jacket portion is constructed to expose a predetermined number of key-tip portions for operation. Means are provided to releasably secure the jacket portion to a position adjacent the matrix portion to allow the interchanging of jacket portions each having different numbers of key-tip portions available for depression to meet changing business conditions. | ||||||

| 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.

| 37 | Stroke coded keyboard switch assembly | US3743797D | 1971-08-30 | US3743797A | 1973-07-03 | HOFFMAN C |
| A stroke coded keyboard utilizes a switch matrix having crosspoints comprising deformable membrane switches. The crosspoints are connected in selected sequential pairs to deformable membrane contacts which define the elements or characters of the keyboard. An element can be keyed very rapidly by the stroke of a stylus on the top surface of the keyboard which sequentially closes the contacts defining the element. The keyboard can be utilized in many configurations such as a data entry keyboard, repertory dialer, or in parallel with or as a replacement for telephone keyboards. The character element is defined by the signals generated by a specified sequence of connections of i pairs of first (n) and second (m) conductors so that (nm) distinct characters can be defined on the keyboard by N + M conductors, where n and m are any positive integers greater than one and i is any positive integer greater than one or less than or equal to nm.

| 39 | Keyboard switch assembly with wire conductor matrix contact array | US3723673D | 1971-10-13 | US3723673A | 1973-03-27 | CLARY J; WIRTZ L |
| 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.

| 40 | Eds serial switch array | US3676616D | 1970-12-21 | US3676616A | 1972-07-11 | WIEDMER FRITZ S |
| In a keyboard, an elastic diaphragm switch array providing mechanical strobe and rollover protection, and/or a serial signal output. The switch includes a diaphragm, a separator, and a switch card. The diaphragm comprises a gold-plated continuous sheet of thin spring material and serves as a ground or voltage plane or voltage adder. The switch card has a conductive switch array (or pie section pattern) at each key location and may have twice as many pie sections as there are bits in the code to be produced or voltage transitions desired in the output, with additional service pie sections as desired. Each pie section is wired directly by double-sided wiring and through-holes in the switch card to the appropriate output code pin, a positive or negative voltage source, or other connection. A key button and distributor is provided for pressing the diaphragm smoothly through the separator to make contact with the corresponding switch card pie section. In each pie pattern, at least one of the pie sections is offset from the center of contact of the key button such that, as the key button is actuated and the diaphragm pressed through the separator, that pie section makes contact at a different point in time to provide a serial code signal output, or provide such service functions as strobe, rollover protection, switch battery power, or the like.
