<p>The assembly has several flat, laterally swivelling contact bridges, retaining between them the stationary contacts to be interconnected. During swivelling they are guided by enclosing bridge casing, the force transfer from the casing to the contact bridges being carried out by stops on the casing. The stops engage the contact bridges in lateral abutment. The stops (10-16) are adjustably mounted in the contact bridge casing (8). Pref., each stop is formed by a bolt (10-13), with an eccentric bearing at each end for mounting in the casing, where it can be latched. At one end the bolt may be fitted with an eccentric square (19) which may engage in an octagonal aperture of the casing for proper latching. A rotary sleeve (15) may be fitted on the latchable bolt and may have an outer stop surface (16), by which it abuts the narrow side of the respective contact bridge (1).</p> |
