Abstract
This miniature relay is obtained by micromachining on a substrate using etroforming, photolithography and/or similar techniques, all its components being obtained on the substrate by integration operations similar to those used for fabricating integrated circuits. A mobile contact (26) is borne by an elastic lever (19) attached, overhanging, to the substrate (1). A lever (19) forms a rocker and is attached to the substrate (1) by means of a deformable connection. At each of its free ends is provided an armature (20, 21) of a magnetic circuit which defines a seat against which the armature can be applied with a magnetic force opposite that generated by the elastic deformation of the lever (19). Each magnetic circuit is additionally provided with at least one coil (10a, 10b, 11a, 11b) which can be selectively excited and can generate a second magnetic force, opposite that of the magnetic circuit, in order, when the armature is applied onto its seat, to release the armature associated with this coil and apply the other armature onto its seat by tilting the lever (19).
