27 48,895 ABSTRACT OF THE DISCLOSURE Electrical apparatus and more particularly vacuum electrical circuit breaker apparatus is taught. The electrical apparatus has a cylindrical movable terminal stem which is to be interconnected with a fixed terminal by way of a flexible conductor which is nevertheless relatively stiff and self supporting. This is accomplished by using interlayered elongated rectangular plates or sheets between the two aforementioned terminals. Connec- tion to the circular stem is made by utilizing offset tabs around the periphery of a central hole at one end of each of the sheets. The offset allows the tabbed opening to be inserted over the stem. After which the tabs are sandwiched or compressed to lie in the plane of the sheet thus causing the edges of the tab to flow around the stem reducing contact resistance. Because there are multiple sheets in each flexible conductor packet, the number of three point contacts between the flexible conductors and the stem is increased.
