A connector (1) is provided with configurable contacts (3) such that the contacts can be connected to each other via a printed circuit (16) comprising strip conductors (20) which connect conductive feed-throughs (19) of said printed circuit. For each contact of the connector, a sliding contact (26) which can be displaced between two positions can be connected or not connected to the contact to which it is opposite. The sliding contacts can be maintained between two stable positions via an insulating grommet (37). In a sunken position, the sliding contacts comprise a conductive end which is in contact with a conductive feed-through of the printed circuit and which is in contact with the contact 3. In a withdrawn position, the sliding contact is only in contact with the conductor opening.
