1. Method of manufacturing a stator element for a rotary electrical switch, according to which a conductive lamellar annulus (10) is enclosed by over-moulding in a substantially annular body (20) consisting of insulating plastic material, the said annulus (10) comprising, projecting externally of the said body, connecting terminals (13) and, projecting internally of the said body, a plurality of radial tabs (11) intended for being bent over axially to form contact studs, characterised in that, prior to the aforesaid moulding, at least one zone (14) of small width is arranged in the portion of annulus (10) embedded in the plastic material (20), in that the aforesaid moulding comprises opposite and at each side of the said zone (14) two recesses (23, 24) the bottom of which is flush with the said switch and whereof at least the radially measured dimension is larger than the said width, and in that the continuity of the said annulus (10) is interrupted in the said zone (14) by cutting out the latter by means of a punch and of a die formed by one (24) of the aforesaid recesses. |
