Abstract: An integrated circuit includes an interconnection part with several metallization levels. An electrically activatable switching device within the interconnection part has an assembly that includes a beam held by a structure. The beam and structure are located within the same metallization level. Locations of fixing of the structure on the beam are arranged so as to define for the beam a pivot point situated between these fixing locations. The structure is substantially symmetric with respect to the beam and to a plane perpendicular to the beam in the absence of a potential difference. The beam is able to pivot in a first direction in the presence of a first potential difference applied between a first part of the structure and to pivot in a second direction in the presence of a second potential difference applied between a second part of the structure.
