| 166 | Area actuated switch array | US193214 | 1980-10-01 | US4360716A | 1982-11-23 | Charles M. Fiorella |
| Disclosed is an area actuated switch which can be used, by way of example, in a keyboard for a calculator, learning aid or the like. An area actuated switch array is formed using two insulating sheets which overlie one another such that one side of each sheet faces one another. Sets of spaced conductors formed on each of the facing sides also overlie one another, and selected ones of said conductors traverse the periphery of the keyboard. A plurality of raised, insulating spacer points are positioned on the facing sides and are in registration and contact with each other. An insulating substrate is formed over the conductors traversing the periphery and this insulating substrate has substantially the same thickness as the spacer points such that the spacer points and the insulating substrate prevent the spaced conductors from making electrical contact. An adhesive coating is applied to the spacer points and the insulating substrate to bond these two parts together. The bond created by the adhesive coating over the insulating substrate prevents contamination of the keyboard from dust, humidity and the like. The keyboard structure, therefore, may have an infinite active area such that when pressure is applied anywhere within the periphery of the switch array, electrical contact is made. | ||||||

Depressing the key causes contact to be made between the respective pad and the first layer of conductive material. The spongy material gives the operator the ''''touch'''' of a standard typewriter keyboard.
