ABSTRACT:
An improved electrical contact including an angular engagement arm for slidably engaging a conductive surface, said arm including a noble metal segment thereon for electrically contacting said surface and means for preventing transfer of material from the arm onto the noble segment. The improvement resides within the material transfer prevention means wherein said means comprises at least one elongated blade having at least one edge thereon, said blade formed so that only the edge slidably engages the conductive surface prior to said noble metal segment contacting said surface. The contact is ideally suited for use within a printed circuit board connector, said connector also disclosed.
