Electrical switch (circuit breaker) having a device for adjusting the relative position between the stationary contacts and switching blades

摘要

In order to adjust the relative position of the stationary contacts (1) and pivoting switching blades (3), which are operated via push rods (10) of electrical medium-voltage switches, an actuating element in the form of an eccentric element (13) (which can be inserted into a recess in the push rod in a positive-locking and force-fitting manner), is arranged between the push rod (10) and the drive unit (11). The eccentric element has a polygonal circumferential contour and is provided with an asymmetrically located hole for accommodating the bolt for connection to the drive unit. <IMAGE>
