Abstract: A touch-sensitive matrix switch assembly includes a pair of transparent insulating substrates having conductive row strips and column strips. The conductive row strips and column strips are separated by longitudinal extending channels, and an insulating spacer strip is deposited in each row channel and in each column channel. The substrates are mounted together with the row conductors extending transversely with respect to the column conductors. An air gap between the row conductors and column conductors is provided by the engagement of the row spacer strips against the column spacer strips. The space strips are formed by very small diameter transparent glass or polymer particles which are mixed with a transparent polymer adhesive in a volatile solvent. The glass or polymer particle/adhesive mixture is sprayed into the channels through a mask to produce a transparent, non-conductive glass or polymer deposit which is enlarged slightly out of the channel, thereby defining a spacer strip. In an analog touch switch assembly, spacer dots are applied onto the surface of a resistive sheet by pneumatically sputtering small diameter transparent glass or polymer particles which are coated by a transparent polymer adhesive.

Abstract: A switch apparatus comprising a nematic curvilinearly aligned phases liquid crystal material located between a pair of electrode means wherein a flexible substrate having a conductive segment formed therein may be positioned in a spaced substantially parallel relation to one of the electrode means. The flexible substrate has sufficient flexibility to deflect toward one of the electrode means in response to the application of pressure thereto so that at least a portion of the flexible substrate is deflected toward one of the electrode means to operatively couple the conductive segment to the electrode means to effect an input of information and to cause a display of the same.

Abstract: A transparent keyboard switch which is suitable for use in switch arrays is disclosed. Switch nomenclature may be positioned behind the switch and viewed from in front of the switch. The transparent switch comprises a relatively rigid electrically insulating transparent substrate having a "lower" electrode disposed on the upper surface thereof and a relatively flexible transparent film having an "upper" electrode disposed on the underside thereof and a layer of electrically insulating fluid spacing the upper electrode from the lower electrode. The switch is rendered conductive by pressing on the flexible film to locally displace the electrically insulating fluid from between upper and lower switch electrodes and bring them into contact, thereby making the switch a closed circuit.

Abstract: An environmentally protected keyboard display and input device which may be utilized in conjunction with a variety of digital control systems such as automated bank tellers or building security systems. The keyboard display and input device includes a unitary, transparent flexible keyboard (16) having thickened portions forming keys (36). The keyboard forms an environmental seal including a peripheral gasket to protect an underlying, transparent, pressure sensitive switching assembly (18), which, in turn, overlies a corresponding visual display (24) of alphanumeric characters which indicate the significance of the individual pressure sensitive switches and corresponding keys overlying each character. Pins (66, 68) are formed on the underside of the flexible keyboard (16), below each key (36), to focus and concentrate pressure exerted on each key to the corresponding presure sensitive switch below. An optical grid (22) is provided to restrict the viewing of the alphanumeric characters to the user of the device, to prevent compromising the data input.
