    Abstract: The invention is directed to a membrane switch comprising a first layer 30 of flexible insulating material and a second layer 50 having relatively inflexible characteristics, each layer 30, 50 having an array of conductors 40, 54 disposed thereon and defining a plurality of switch point areas over a substantial portion of the respective layers. The first sheet is transparent and carries visible symbols on the inner surface thereof formed by a first layer 36 of inks printed thereon and further includes a barrier coating over such symbols to provide contrast therefore. The first array 40 of conductors is printed on the barrier coating. The second array 54 of conductors is printed on the inflexible layer. The first and second arrays 40, 54 of conductors are connected to respective voltage sources, preferably by further arrays of conductors 42, 56 disposed over at least portions of the first and second arrays, 40, 54 the further arrays 42, 56 being of a material having a higher conductivity than the material used for the first and second arrays 40, 54. Spacer means 58 for the switch is formed by printing an array of spaced apart dots of a dielectric and insulating coating on top of at least one of the arrays of conductors in the defined switch point areas to hold the switch point areas normally apart until pressure is placed thereupon to deform the first sheet 30 and effect a switch closure between corresponding switch point areas of the arrays 40, 54. A method for making the switch is also disclosed.

    Abstract: A keyboard system comprises a circuit board having a matrix of contact switches. A module comprises a matrix of keys in actuating correspondence with the contact switches. The keys are of a resilient elongated form having at the terminus an upwardly projecting contact button and a pair of downwardly projecting pegs. One peg contacts a contact switch for actuation thereof. The other peg is receivable in a recess in the circuit board for maintaining alignment of the key. The module also forms a support for an overlying membrane wherein manual depressing of selective locations of the membrane actuates a corresponding contact switch.

    Abstract: Relates generally to the production of electrical signals from a keyboard, each key of which is individually operatively associated with a switching device whose activation to electrical conductive condition is controlled by the displacement of the key. These switches are hermetically sealed from the atmosphere and are electrically scanned in succession at relatively high speeds and at a repetitious rate such that several scanning cycles occur during the normal activation of a selected key. The keyboard mechanism also includes a shift register having one more bit position than the number of switch devices and into which a bit is introduced into the "one" position at the instant the scan encounters a closed switch of the keyboard. This bit is then shifted through the register in timed relation to the scan of the remaining key switches and unloaded into the last bit position of the register. A detector senses the presence of a bit in both the "one" position and the last position of the shift register and upon detection of a bit solely in the one position it delivers a signal indicative of the character represented by the actuated key and upon detecting bits in the two extreme positions of the shift register it nullifies the delivery of such a signal.

    Abstract: Different from conventional push-button switches with which an electric circuit is closed and opened as the button top is pushed with a finger tip and as the finger tip is withdrawn from the button top, respectively, the inventive push-button switch operates in a unique manner that the electric circuit is opened already as the pushing force by the finger tip is still on the way of increasing. The inventive push-button switches utilize the delicate snap back action taking place as the strain in the snap spring portion in the diaphragm covering of the switch exceeds a certain critical point so as to spontaneously pull apart the movable contact member on the inward surface of the covering from the fixed contact points on the base plate while the button top is still under pushing with a finger tip. The inventive push-button switch is advantageous because of the absence of the transient disturbances in the circuit such as chattering and bouncing.

    Abstract: A composite top membrane designed for use with membrane-type switch arrays which is substantially smooth and ripple free. The composite membrane comprises:(1) a layer of plastic foam which is coated on each side with a pressure sensitive adhesive;(2) a decorative cover layer formed from plastic and having graphic indicia on one or both surfaces and which is adhesively affixed to one side of the aforementioned layer of plastic foam; and(3) a sheet of plastic having a significant memory property having its first surface adhesively affixed to the other side of the foam layer and a pattern of conductive metallization on its second surface.The layer of foam material provides a flat, resilient interface between the decorative cover layer and the relatively convoluted surface of the flexible printed circuit top membrane. As such, the decorative layer remains flat and free from optical irregularities which would detract from its aesthetic impression.
