Each of a plurality of touch pads for detecting manual contact by a human user and capable of activating a control device comprises a dielectric substrate (10) of substantially uniform thickness. A first thin conductive electrode pad (16) is disposed on a first surface of the substrate in a closed, continuous geometric form having an area which affords substantial coverage by a human appendage. A second thin, conductive electrode (18) is also disposed on the first surface of the substrate (10) and surrounds, but is spaced from, the first conductive electrode (16) on peripheral edges having an adjacent touch pad. <IMAGE> |
