A rolling contactor for providing electrical signal communication between a component terminal and a support structure for the rolling contactor, including an electrically conductive circular roller having formed thereon an outer rolling surface and an inner, centralized hole, between two, spaced-apart side walls, for rolling across the termination surface of a device under test (DUT), at least one electrically conductive circular spool of smaller outside diameter than the roller, located adjacent and in contact with one of the roller side walls and having formed therethrough a centralized hole, a support axle adapted to pass axially through the holes formed in the roller and the spool and extending there beyond, an electrically conductive axle bracket adapted to support the axle in a rotational arrangement about the axle to allow the roller surface to rotate and press against the termination surface of the DUT, an electrically conductive brush extending from the axle bracket to contact the spool in tangential arrangement during rotation thereof, and an electrically conductive elongated spring arm extending between the axle bracket and the support structure, to complete the electrical path between the termination surface of the DUT, the roller surface and the spool in contact with the axle bracket through the conductive brush, and to provide spring pressure to press the roller against the termination surface.
