ABSTRACT In an electric switch the contact portion of a fixed contact (3) is convex while the co-operating contact portion of a movable contact arm (5) is concave and of larger radius of curvature whereby lateral operating forces on the contact arm (5) cause the contact portions to roll rather than slide over each other in order to keep fretting to a minimum.
