Abstract: A strain sensitive columnar transducer for a data entry keyboard contains a column upstanding from the keyboard. Strain sensitive orthogonally oriented patterns are formed on a single flexible planar sheet which is sliced to place each of the patterns on a separate tab. The planar sheet is forced over the column so that the patterns lie up against the sides of the column to measure force exerted on the column.
