Manual control device for a remotely operated source inverter

A device for controlling the switching of the contacts in an electrical apparatus comprising a unit inside which are mounted a control lever in a pivot connection with the unit and configured to be rotationally displaced between a first position corresponding to a position;

• wherein the contacts are closed on a primary power supply and a second position corresponding to a position,
• wherein the contacts are closed on a secondary power supply, a rotating element connected to the lever by an intermediate shaft, an actuating shaft mechanically connected to the rotating element and to electrical contacts and configured to pivot between a first and a second position to switch between the electrical contacts, the unit further comprising a slot traversed by the lever to allow it to be actuated from outside the unit in a manual operating mode of the device;
• wherein it comprises a torsion spring including a first end cooperating with the control lever and a second end cooperating with the rotating element;
• and
• a first pawl and a second pawl scissor-mounted via a torsion spring, the first pawl cooperating, in a manual operating mode of the device, with a first stop of the rotating element in a first position of the rotating element and with a first cam track of the control lever to disengage the first pawl from the first stop and release the rotating element;
• and
• the second pawl cooperating, in a manual operating mode of the device, with a second stop of the rotating element in a second position of the rotating element and with a second cam track of the control lever to disengage the second pawl from the second stop and release the rotating element.
