Abstract
An operating mechanism for opening and closing at least two contacts simultaneously is provided. The operating mechanism includes a base frame and a bridge body having an elongate contact surface with a length and a width. The elongate contact surface is configured to extend in a length direction over and be in contact with operating rods of the at least two contacts. The operating mechanism further includes a first reaction arm extending substantially parallel to the length of the elongate contact surface and a second reaction arm extending parallel to the first reaction arm and at a distance of the first reaction arm in the direction perpendicular to the elongate contact surface. The operating mechanism also includes a rod mechanism of two links and a cam arranged on a shaft.
