  • the triggering mechanism is adapted to actuate the control mechanism 25 for the switching of each switching member 20A, 20B, 20C.
  • the trigger mechanism is known per se.
  • Each elastic coupling element 135 is designed to collaborate with the mechanical referencing member 30 by snap-fastening.
  • the elastic coupling elements 135 are aligned in the transverse direction Y.
  • Each elastic coupling element 135 is carried by the lower face 125.
  • Each elastic element 135 comprises two elastic branches 155 delimiting a first cavity 160 for receiving the mechanical referencing member 30.
  • the elastic arms 140 delimit a second cavity 165 for receiving the post 145 and a second opening 170 for introducing the post 145 into the second receiving cavity 145.
  • Each elastic arm 140 has come integrally with the casing 70.
  • Each elastic arm 140 has a width, measured in the transverse direction Y, of less than or equal to 6 mm. Because of their flexibility and their small width, the elastic arms 140 therefore do not prevent rotation, around the longitudinal direction X or the vertical direction Z, between the auxiliary module 35 and the spacer 45.
  • the tenon 145 came integrally with the main wall 95.
  • the tenon 145 has a cylindrical shape with a circular base around the transverse direction Y.
  • the tenon 145 has a rectangular 175 base and a cylindrical head 180 with a circular base around an axis parallel to the transverse direction Y.
  • the projection 150 is, for example, cylindrical with a circular base around the transverse direction Y.
  • the projection 150 has a second diameter D2, measured in a plane perpendicular to the transverse direction Y, equal to 64 mm.
  • the projection 150 has a height, measured in the transverse direction Y. The height of the projection is, for example, equal to 0.5 mm.
  • the projection 150 forms with the control mechanism 25 a mechanical connection of the "point connection" type. Indeed, the second diameter D2 of the projection 150 is much smaller than the dimensions of the auxiliary module. In particular, the contact surface between the flange 60 and the projection 150 is less than one-fiftieth of the surface of the first lateral face 115A.
  • the mechanical connection between the projection 150 and the control mechanism 25 therefore eliminates a single degree of freedom between the control mechanism 25 and the auxiliary module 35.
  • the mechanical connection between the projection 150 and the control mechanism 25 therefore allows five degrees of freedom between the control mechanism 25 and the auxiliary module 35.
  • Each elastic branch 155 came integrally with the envelope 70.
  • the elastic branches 155 delimit a first opening for introducing the mechanical referencing member 30 into the first receiving cavity 160.
  • the first opening has a first internal width Li1 defined as the minimum distance between two points of the elastic branches 155.
  • the first internal width Li1 is strictly less than the first diameter D1 of the mechanical referencing member 30.
  • the maximum distance, measured in the transverse direction Y, between two points of the elastic branches 155 is equal to 15 mm.
  • the elastic branches 155 therefore prevent the auxiliary module 35 from pivoting, relative to the mechanical referencing member 30, around the vertical direction Z and around the longitudinal direction X, but allow rotation around the transverse direction Y.
  • the elastic branches 155 are configured to elastically deform in order to allow the introduction of the mechanical referencing member 30, through the first introduction opening, into the first receiving cavity 160.
  • the first receiving cavity 160 is cylindrical with a circular base around a second axis A2.
  • the second axis A2 is merged with the first axis A1.
  • the second axis A2 is therefore parallel to the transverse direction Y.
  • the first receiving cavity 160 has a first internal diameter D3 greater than or equal to the first diameter D1 of the mechanical referencing member 30.
  • the second receiving cavity 165 is cylindrical around a third axis A3.
  • the third axis A3 is parallel to the transverse direction Y.
  • the second receiving cavity 165 has a flat surface 182 opposite the second introduction opening 150 in the vertical direction Z.
  • the second receiving cavity 165 has a second internal diameter D4 greater than or equal to the diameter of the head of the post 145.
  • the second receiving cavity 165 is configured so that, when the head 145 is received in the second receiving cavity 165, the head 145 is supported on the flat surface 182 of the second receiving cavity 165.
  • the second opening 170 has a minimum distance between two points of the elastic arms 140 which is strictly less than the diameter of the head 180 of the stud 145. This minimum distance between two points of the elastic arms 140 is measured in the longitudinal direction X.
  • the base 175 is parallelepiped.
  • the base 175 has a width, measured in a plane perpendicular to the vertical direction Z, strictly less than the minimum distance between two points of the elastic arms 140.
  • the head 180 has a diameter strictly greater than the width Lb of the base 175.
  • the switching device 10 allows precise positioning of each auxiliary module 35 relative to the control mechanism 25 by means of the mechanical referencing member common to the control mechanism 25 and to each auxiliary module 35.
  • the switching device 10 allows, by virtue of its architecture, precise positioning of each switching member 20A, 20B, 20C relative to the control mechanism 25.
  • the mechanical referencing member 30 is common, in addition, to each switching member 20A, 20B, 20C.
  • the direct mechanical couplings of the auxiliary module 35 with the spacer 45 and the control mechanism 25 allow easy installation of the auxiliary module 35 in the housing 15, requiring few parts.
  • the number of mechanical connections between the auxiliary module 35 and the control mechanism 25 is therefore reduced.
  • the actuation of the control mechanism 25 by the auxiliary module 35 is therefore more reliable.
  • the assembly of the auxiliary module 35 is isostatic.
  • the dimensional dispersion between the auxiliary module 35 and the control mechanism 25 is therefore reduced.
  • the actuation of the control mechanism 25 by the auxiliary module 35 is, here again, more reliable.
  • FIG. 5 Another embodiment of the auxiliary module 35 is shown in the figure 5 . Elements identical to those of the first embodiment of the auxiliary module of the figures 2 to 4 are not described again. Only the differences are highlighted.
  • the auxiliary module 35 is a trigger triggered following the detection of an electrical fault of the first current or following a voluntary command and suitable for actuating the control mechanism 25 in the event of detection of the electrical fault or of the voluntary command.
  • the auxiliary module 35 does not have a second guide member 85B.
  • the auxiliary module 35 has at least one elastic retaining projection 185. On the figure 5 , the auxiliary module 35 comprises two elastic retaining projections 185.
  • Each elastic retaining projection 185 is configured to prevent the auxiliary module 35 from being withdrawn from the housing 15.
  • Each elastic retaining projection 185 is able to collaborate with a cavity in the housing 15 by snap-fastening.
  • Each elastic retaining projection 185 is carried by a lateral face 115A, 115B of the casing 70. Each elastic retaining projection 185 is made integrally with the casing 70. Each elastic retaining protrusion 185 has a cam surface 190 and a stop surface 195.
  • the cam surface 190 is inclined relative to the vertical direction Z, and oriented towards the bottom of the housing 15.
  • the cam surface 190 is able to cooperate with the housing 15 to drive, during the introduction of the auxiliary module 35 into the housing 15, the deformation of the lateral face 115A, 115B towards the inside of the envelope 70.
  • the abutment surface 195 is perpendicular to the vertical direction Z and oriented towards the cover 40.
  • the abutment surface 195 is configured to abut against a blocking surface, not shown, of the housing 15 when a force directed in the direction vertical Z is exerted by an operator to extract the auxiliary module 35 from the housing 15.
  • the auxiliary module 35 cannot be manually removed from the housing 15 by an operator.
  • the switching device 10 is then more secure. This is in particular important in the case of triggers capable of detecting an electrical fault, which are intended to be arranged in the factory in the housing 15 and to remain in place throughout the life of the switching device 10.
  • the arms 140 which delimit the cavity 165 for receiving the head of the post 145 are flexible and have a small width in the transverse direction Y.
  • a rotation rotation, around the longitudinal direction X or the vertical direction Z, between the auxiliary module 35 and the spacer 45 is therefore possible.
  • the second receiving cavity 165 has a second internal diameter D4 greater than or equal to the diameter of the head of the post 145.
  • the arms 140 do not enclose the head of the post 145 and that the mechanical connection between the auxiliary module 35 and the spacer 45 is a connection eliminating a single degree of freedom, by the support of the head 145 on the flat surface 182.
