Classification: CPC H | IPC H

Claim 0:
1. A device for switching a medium-voltage electrical circuit, comprising:
a vacuum interrupter comprising a fixed electrode and a mobile electrode,
an actuating lever linked to the mobile electrode, the actuating lever being mobile between a first position, called an opening position, wherein the mobile electrode and the fixed electrode are separated by an opening distance, and a second position, called a closing position wherein the mobile electrode and the fixed electrode are in contact so as to allow a current to flow through the electrical circuit,
the actuating lever moving from the first position to the second position defining a travel of displacement,
an insulator linked to the actuating lever,
a compression member, exerting a repelling force between the mobile electrode and the insulator,

wherein the travel of the actuating lever is greater than the opening distance, the switching device comprising:
an indicator stem mechanically linked to the mobile electrode, which is configured to extend at least partly out of the insulator when the actuating lever is in the closing position, wherein the indicator stem passes through the insulator.
