- the distribution element and the transmission element are so relative to each other led to a sliding movement of the distributor element essentially transverse to the actuation movement to one Movement of the transmission element essentially parallel to the actuating movement and to actuating the Leads.
- the actuating means according to the invention have Distribution element and a transmission element.
- the Distribution element is from the actuator in Essentially transverse to the actuating movement of the Shifting distances shifted.
- the transmission element is on the panel arrangement substantially parallel to the Actuating movement of the switching sections guided and is connected to the switching paths. A Movement of the distributor element leads to a Movement of the transmission element and thus to one Actuation of the switching sections.
- the actuating means according to the invention have a particularly simple construction with very few components on. They are particularly robust and less susceptible to Wear or other failures.
- the distributor element and the transmission element over guide grooves and therein guided guide elements are guided relative to each other.
- the distributor element advantageously has Guide grooves in which guide elements of the Transmission element are guided.
- the history of the guide grooves is such that a sliding movement of the distributor element substantially transversely to that Actuating movement of the switching sections to one movement of the transmission element substantially parallel to that Actuation movement leads.
- the parallel movement is on transmit the switching distances, and the switching distances are switched on or off.
- the distributor element 9 via at least two lever elements on the Panel arrangement is guided.
- the lever elements are like this arranged that the distributor element a movement relative to the panel arrangement substantially transverse to the Can perform actuating movement of the switching paths. More specifically, the lever elements are with their first End at the panel arrangement and with her opposite second end to the distributor element rotatably attached so that the attachment point of the Distribution element at the second end of the lever element the attachment point on the panel arrangement on a Circular arc rotates. With relatively small deflections of the Lever element and with a corresponding arrangement of Lever elements can this circular arc-shaped movement than in Essentially transverse to the actuation movement be designated.

- the transmission element is advantageously as a profile with a U-shaped Cross section formed.
- the two legs of the U-shaped Profiles form the ones arranged parallel to each other Transfer element plates. Between the two legs the distributor element is arranged.
- the actuating means means for Generation of a contact force between switch contacts Switching distances when the switching distances are closed have that between the actuator and the Switching distances are arranged. It is conceivable that the Contact strength through appropriate training of Guide grooves is generated. The could Guide grooves a guide area with a relative have a slight slope along which the Distribution element or the transmission element is guided, if the switching distances are already closed. Thereby is a contact force on the closed switching contacts exercised.
- the means for generating a are advantageously Contact force formed as contact force springs between the transmission element and the switching paths Act.
- the guide grooves between the distributor element and the transmission element are formed so that the Transmission element continued along a slope will continue towards the closed position of the Switching distances is moved, although the switching distances are already closed. This creates a contact force on the switching contacts of the switching paths, the size the contact force from the design of the contact force springs is dependent.
- the contact force springs are advantageously as cylindrical helical compression springs educated.
- the guide grooves between the distributor element and the Transmission element have an increasing course.
- the slope of the guide grooves must be designed so that moving the manifold element essentially transverse to the actuating movement of the switching distances to one sufficiently large movement of the transmission element in Essentially parallel to the actuation movement of the Switching paths leads to the switching contacts of the Switching distances at least from their open to one contact contact position and vice versa can. If on the switch contacts in their contact contact position additionally a contact force to be exercised, the guide grooves must be so be interpreted that a further movement of the Distribution element substantially across the Actuation movement another movement of the Transmission element in the direction of the closed position which causes switch contacts.
- the Guide grooves two merging guide areas have different slopes, with the First close the switching paths Guide area with the larger slope for moving the Switch contacts of the switching paths from the open to the contact position and then the second Guide area with the smaller pitch for compression of contact force springs and for generating contact force the switch contacts in the contact-making position is driven through.
- the second Management area changes into a third management area, which is almost transverse to the actuating movement of the Switching distances runs and for setting the Switch contacts of the switching paths in the position under contact force.
