    摘要: The present invention relates to a device (1) for switching current, for switching an electrical load (C) in an electrical power circuit, comprising at least one current switch (10, 10a, 10b, 10c, 10d, 10e) and characterized in that it also comprises an electronic current limiter (2) placed in series with the said current switch (10) and means (20) of control of the electronic current limiter (2) able to command the activation or the deactivation of the electronic current limiter (2). These means (20) of control exhibit the feature of being coupled to the current switch (10) so that, prior to any switching, the means (20) of control activate the electronic current limiter (2) so as to obtain during switching a current having a value below or equal to a determined threshold value.
