<p>A metallic electrical contact element is disclosed having a discrete convex curvilinear surface portion intended for electrical contact having a localized conductive electrodeposited contact point thereon. The contact point is produced by providing a roller carrying electrolyte on its periphery for plating said contact point, positioning the metal contact element transversely to the axis of the roller with the periphery of the roller in tangential engagement with the contact point, rotating the roller while passing on electric current between the contact point and the roller surface whereby a conductive electrical contact point is produced on the convex curvilinear surface. The thickness of the electrodeposited contact point smoothly decreases outwardly from the center thereof. Such a metallic contact element reduces the amount of material used in plating the electrical contact point.</p> |
