A contactor has two contact elements (1, 2) each having a contact member (3, 4) adapted to bear with the contact side (5, 6) thereof against a said contact side of the other contact member for enabling an electric current to flow between said to contact elements. The contact sides of both contact members are provided with serration's (11, 12) extending so that elongated ridge-like peaks (13) of serration's of one said contact side intersect such peaks of the other said contact side while forming a plurality of spots of mutual contact of these contact sides distributed over the area of said contact sides.
