An electro-conductive contact structure for sealing the interior of an enclosure from interference includes first and second electro-conductive contact surfaces. In one embodiment, the first electro-conductive contact surface includes a plurality of projections, and the second electro-conductive contact surface includes a plurality of slots. The projections are configured for insertion into the slots to form an electro-conductive interface between the first and second portions of the enclosure. In another embodiment, the electro-conductive contact structures are formed on first and second housing parts, respectively. In another embodiment, the electro-conductive contact surfaces each include a series of fingers and a plurality of pockets between the fingers.
