Abstract
A device for switching a medium-voltage electrical circuit, including: a vacuum interrupter including a mobile electrode, an actuating lever linked to the mobile electrode and mobile between an opening position and a closing position, an insulator linked to the actuating lever, a control fitting secured to the mobile electrode, and an elastic return, for example, a spring, exerting a return force between the control fitting and the insulator, wherein a travel of displacement of the actuating lever is greater than the opening distance such that the control fitting is distanced from the insulator when the actuating lever is in the closing position. The switching device further including an indicator stem secured to the control fitting, which is configured to extend at least partly out of the insulator when the actuating lever is in the closing position.
