Abstract
A switching mechanism for a switching device is disclosed. In at least one embodiment, the switching mechanism includes a contact element which is mounted in a switching shaft segment such that it can rotate and can be switched off automatically in the event of a fault via said switching mechanism, a switching lever for switching the contact element on and off manually; a cocking lever which is mounted in a fixed position such that it can rotate and interacts with a catch; and a toggle lever joint including a coupling lug for connection to the contact element, a pivoting lever and a toggle lever joint shaft. The switching lever can assume at least one switched-on position, a manual switched-off position or automatically unlatched tripped position, or an intermediate switch position which is located between the switched-on position and the tripped position when a contact element is welded. According to at least one embodiment of the invention, the switching link of the switching lever has at least one blocking element, which interacts with the coupling lug such that the switching lever remains in the intermediate switch position if an opening operation is carried out when a contact element is welded.
