Abstract
The device is for an installation suitable for operation under several different operating modes and permits the switching automatically from one mode to the other. Series connected control elements control respective system operating modes. Control or detection elements control the choice of operating mode and actuate or cause blocking of static switches which are each parallel connected with at least one of the electrical control elements. The electrical resistances of the control elements are chosen to be of magnitudes sufficiently different so that when a current passes through several series connected elements the one with the highest resistance is fed with a voltage sufficient to operate it.
