Abstract
A power switch includes a vacuum interrupter held in a pole shell including a fixed contact and a moving contact, and a drive rod embodied in an electrically insulating fashion in order to apply a driving movement of a switch drive to the moving contact in order to open and close the contact system of the vacuum interrupter. Furthermore, a method is disclosed for avoiding incorrect orientations of the drive rod of such a power switch. A guide and/or centering element is proposed, connected to the drive rod and provided radially between the drive rod and the pole shell to bring about independent axial orientation of the drive rod in the pole shell.
