Abstract
An electric switching system comprises first, second, and third input terminals, first, second, and third output terminals, an electric switching module, and a control module. The electric switching module includes two first switches and two second switches, each switch having a fixed input contact, a fixed output contact, and a mobile contact. Fixed input contacts are connected to fixed output contacts via mobile contacts in a closed position and insulated from each other in an open position. A holder member is configured to be moved by an electric driving device between a first position and a second position. The holder member includes a first mechanical coupling element and a second mechanical coupling element. The control module includes the driving device. The holder member is mechanically coupled to the driving device via the first coupling element in a primary configuration or via the second coupling element in a secondary configuration.
