  • the latter is perpendicular to the lateral face 29 and has an axis 33 projecting at both ends of the spar 31 so as to pivot the control module 1 on the base 3.
  • the spar 31 also has a groove 35 in its length to allow the latching of the two parts 25 and 27 of the support.
  • the side face 29 has, at its other end, two holes 37 and 39 intended to provide the connection between the two parts 25 and 27 of the support 19 and whose roles will be specified in the following description.
  • the portion 27 of the support 19 has a lateral face 41 and a longitudinal side, constituting the rear wall 43, perpendicularly connected to one another at their ends. At its other end, the lateral face 41 supports a rod 45 which extends parallel to the rear wall 43 and ends with a hook 47. The latter is snapped into the groove 35 during assembly. The lateral face 41 is also pierced, near the rod 45, with a hole 49 allowing the end of the spar 31 to fit together.
  • the rear wall 43 carries, in its outer extension, another hook 51 and a pin 53. The latter is inserted into the hole 37 of the element 25 described above. The hook 51 comes to him, snap into the hole 39 during assembly.
  • the rear wall 43 has a base 55 to which are fixed four flexible electric blades 57 which extend parallel to the lateral face 41 of the portion 27 so as to come into contact with the electrical tracks 9 of the base 3, once the assembly completed.
  • the switch 23 is also fixed to said base 55 so as to face the base 3 once the elements are assembled, as shown in FIG. figure 4 .
  • the rear wall 43 further comprises an appendix 59 on its outer face which is positioned in the fastener 17 of the base 3.
  • the side faces 29 and 41 are respectively pierced with holes 61 and 63, the latter are aligned, once the parts 25 and 27 snapped, in order to accommodate the rotary control member 21.
  • An electrical circuit 65 integrated by an overmolding technique extends in a circular manner on the inside of the lateral face 41 of the part 27 of the support 19 and connects the flexible electrical blades 57 of the rear wall 43.
  • the electric tracks of the blades For two of them, the hoses 57 correspond to the electrical signal coming from the rotary member 21, the third to the signal from the switch and the last to the electrical ground.
  • the electrical part of the support 19 of the control module 1 is carried by the portion 27, the portion 25 being only mechanical.
  • the electrical circuit 65 is controlled using the rotary member 21 carried by the support 19.
  • the control member 21 is made of several parts assembled to perform the electrical functions of control, manipulation and indexing, this last being preferably magnetic.
  • the manipulation function is achieved by means of a cylindrical sleeve 67 whose outer periphery is fluted to facilitate the application of a rotary control, by example by a user's finger.
  • This sleeve 67 has at its end 68 in front of the circuit 65 an annular wall portion carrying a scraper 81 with three branches intended to be in contact with the circuit 65 to obtain an electrical signal representative of the rotational position of the sleeve 67
  • Each branch is made by a pair of fins 83 to obtain a double contact to reduce the risk of malfunction.
  • the sleeve 67 is rotated by the drum 69 with a through axis 71, one end of which is housed in the hole 63 and the other end of which is housed in the hole 61.
  • grooves 85 On the periphery of the drum are provided grooves 85 shifted at 120 ° which cooperate with complementary ribs (not visible in the figures) on the inner cylindrical wall of the sleeve 67.
  • the rotational movement of the sleeve is indexed by an indexing unit magnetic rotor 75 formed by a rotor 77 carried by the drum 69 and a stator 79 carried by the side face 29.
  • the rotor 77 and stator 79 are disks having magnetic sectors alternating pole "north" and "south” pole. Alternatively, one of the polarities (“north" or "south”) can also be replaced by non-magnetic sectors.
  • the fixing of the rotor 77 on the drum 69 on the one hand and the stator 79 on the lateral face 29 on the other hand is achieved by a fixing with tenons and complementary notches.
  • the drum 69 carries on its axis 71 on the opposite side to the indexing unit 75 a helical spring 73 intended to hold the various elements of the rotary control member 21 in position by pressing on one side on the face side 41 and the other side against the drum 69.
  • stator 79 and the rotor 77 fit respectively on the lateral face 29 and on one side of the drum 69. On the other side of the latter are snapped on the one hand the spring 73 around of the axis 71 and secondly the sleeve 67 on the outer diameter.
  • the two parts 29 and 41 of the support 19 are positioned on either side of the rotary member 21. Their bringing together, until their snap-in, is accompanied by the introduction of the ends of the axis 71 into the holes 61 and 63, the contacting of the wiper 81 with the electrical circuit 65 and the proximity of the rotor 77 and the stator 79.
  • the axis 33 of the module 1 can be inserted into the notches 15 of the base 5.
  • the appendix 59 can then snap into the fastener 17 of the base 5, causing the flexible blades 57 to come into contact with the electrical tracks 9.
  • the rotary member 21 can rotate about the axis 71, itself carried by the support 19.
  • the latter can rotate about its axis 33, itself supported by the notches 15. Nevertheless, the pivoting is blocked in one direction by the fastener 17 and in the other by the base 5 via the switch 23.
  • the device according to the invention is distinguished by its simplicity of assembly and the fact that the control module carries the entire electrical switching circuit.
  • the user rotates the rotary control member 21 by applying a force tangential to the rotary control member 21.
  • the magnet sectors of the rotor 77 then transiently pass into a position where they are facing magnetic sectors of the stator 79 of the same polarity.
  • the magnetic fields repel and cause a slight shift of the rotor 77 along the axis 71 and the compression of the spring 73.
  • This position is unstable.
  • the user feels a resistance and the passage of a hard point.
  • the operator continues the rotational movement of the member 21, the following stable position is reached corresponding to magnetized sectors of the rotor 77 facing areas of opposite magnetization of the stator 79.
  • the return to a stable position is facilitated by the return force of the spring 73.
  • the signal corresponding to the change of the positions of the contact points of the wiper 81 on the electrical circuit 65 is delivered by the latter via the flexible blades 57 to the microprocessor (not shown).
  • the operator presses on the rotary member 21.
  • the force applied is transmitted to the support 19, which causes it to pivot about the axis 33 and the closing of the switch 23, causing the transmission of a validation signal via the flexible blades 57.
  • the two signals coming from the rotary control member 21 are, for example, two square wave signals, one being out of phase by one third of a period with respect to the other.
  • the microcontroller can thus by analyzing the two received signals deduce the direction and amplitude of the rotation.
  • the present invention can be applied, for example, to a speed regulator of a vehicle.
  • the speed reference can be incremented or decremented by means of the rotary control member 21 until the desired desired value is reached.
  • the validation by pressing on the rotary control member 21 allows the activation of the controller and causes the control of the speed of the vehicle to the preselected set value.
  • Another possible application is the use of a drop-down menu on a screen.
  • the rotary control member 21 makes it possible to navigate through the different items of the drop-down menu.
  • the validation by pressing on the rotary control member 21 activates the selected item.
  • the present invention is very advantageous because of its compact form facilitating its installation and its reliability, especially at its electrical contacts, ensuring optimal operation and life.
  • the invention allows assembly and simplified assembly which facilitates the production in large numbers.
