Abstract

A touchpad apparatus extends, without having to be covered by a cover, up to an outer housing edge of an operating device. In two possible cases, not only touchpads and connections between the touchpads in the touchpad area are formed by patterns of conductive strips which cannot be resolved by the human eye, but also contact connection lines which connect contact elements to each other at two sides of the touchpad area.
