Abstract
A new and efficient input device of an electrode contact type which has a high mechanical strength and durability and can assure accurate detection of coordinates. The input device comprises an elastic flexible insulator spacer having a conductive element embedded therein which may be a gauze of thin wires of a good conductive material knit into the form of a grid. Upon depression of an insulator protective sheet, a portion of the spacer under the sheet is deformed to expose the conductive element downwardly therefrom thereby to short-circuit the element to a resistor layer under the spacer.
