An electrical connector for interconnecting a pair of circuit members (e.g., printed circuit boards) wherein the connector includes a plurality of electrical contacts, these contacts including at least one semi-spherical end portion for engaging a respective conductor on one of the circuit members. Significantly, the semi-spherical end portion is capable of moving in two different directions of rotation during such engagement to provide an effective wiping motion against the surfaces of the member's conductor. In one embodiment, the connector includes contacts with opposed, semi-spherical end portions, while in another embodiment, a singular semi-spherical end portion is taught.
