1. A capacitive touch pad comprising cover and first layers, the cover layer comprising a non-conductive cover providing galvanic isolation of the first layer, the first layer comprising a plurality of row-shaped row-sensing electrodes and a row-by-column array of column-sensing electrodes, each column of column-sensing electrodes interconnected by conductive traces, the row-sensing electrodes and column-sensing electrodes defining interleaved combs therebetween, each column-sensing electrode overlapping at least two row-shaped, row-sensing electrodes, each comb comprising at least two fingers.
