Abstract
An electrical switching device including an electric power switching module including a block of three input terminals and three output terminals, each input or output terminal being connected to a stationary contact of an electrical switch also including a mobile contact, configured to switch between an open position and a closed position, the mobile contact configured to be moved by an electromagnetic drive mechanism, and a control module, including at least one control input terminal and at least one control output terminal. The control module includes the electromagnetic drive mechanism configured to be supplied by the control terminals to control a position of one of the mobile contacts. A supervision module includes an auxiliary input contact terminal and two auxiliary output contact terminals, the auxiliary input contact terminal being shared by the two auxiliary output contact terminals, the power module being removable separately from the control and supervision modules.
