Abstract
A touch sensor, such as a capacitive touch sensor, includes a substrate having at least one passageway established therethrough. A first conductive coating is established at a first surface of the substrate, and a conductive element is disposed at the substrate and at least partially through the passageway. The conductive element establishes conductive continuity between the first surface and second or opposite surface of the substrate. The passageway may comprise multiple passageways and is/are established inboard of a perimeter edge of the substrate. The conductive element may include a first conductive material disposed at the first surface and partially into the passageway and a second conductive material disposed at the second surface and partially into the passageway, whereby the conductive materials contact one another in the passageway to establish conductive continuity between the first and second surfaces of the substrate.
