ABSTRACT:
The invention relates to a drive device for a switching tube with a fixed and movable contact part, said movable contact part being controlled by a plastic switch rod (SS) which remains substantially unstressed when the contact parts are connected or disconnected and the force of the contact spring (KF) when the contact parts are connected is approximately fully exerted on the movable contact part of the switching tube. The actuating lever and the pendulum lever are replaced by drive levers (AH, AH′) having a triangular contour and which are fitted with a pivoting rotational bearing (SL . . . ) in each corner area, said drive levers (AH . . . ) being provided with a centrical pivoting bearing (SLm) for receiving the rotationally mounted contact spring (KF) and the centrical pivoting rotational bearing (SLm) between an upper pivoting rotational bearing (Slo) connected to the switch rod (SS) and a lower pivoting rotational bearing (SLu) connected to the drive (AT) of the movable contact part and the contact spring (KF) is mounted on one side in a fixed spherical cap guide (KG). The contact pressure force for the drive (AT) of the movable contact part can be regulated by altering the active path length of the contact spring (KF). The active path length of the contact spring can be continuously adjusted by a regulating screw (RS) which is accessible from the outside.
