The invention relates to a surgical coupling system which comprises first and second surgical coupling devices each having at least two electrical coupling contacts that are moveable mechanically into engagement with one another. The coupling devices are completely separated from each other in a separated position and are mechanically in engagement with one another in a mechanical coupling position. The system further comprises an electrical switching device which, in the coupling position, is moveable from an OFF position, in which at least one first electrical coupling contact of the first coupling device and at least one first electrical coupling contact of the second coupling device are out of engagement, into an ON position in which the at least one first electrical coupling contact of the first coupling device and the at least one first electrical coupling contact of the second coupling device are in electrically conductive contact or engagement.
