Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne un commutateur électrique.The present invention relates to an electrical switch.

Elle concerne plus particulièrement un commutateur électrique comprenant un socle, un entraîneur monté basculant dans le socle entre deux positions stables pour mettre en contact ou hors contact un élément de contact mobile avec un élément de contact fixe, et un élément compressible selon un axe de compression, l'élément compressible étant adapté à être inactif vis-à-vis de l'entraîneur, pour laisser l'entraîneur libre de prendre l'une ou l'autre des deux positions stables, et à être reçu entre une surface d'appui et l'entraîneur et contraint contre l'entraîneur, pour obliger l'entraîneur à prendre une seule des deux positions stables.It relates more particularly to an electrical switch comprising a base, a driver pivoted in the base between two stable positions to put in contact or out of contact a movable contact element with a fixed contact element, and a compressible element along a compression axis , the compressible element being adapted to be inactive with respect to the driver, to allow the free trainer to take one or the other of the two stable positions, and to be received between a support surface and the coach and forced against the coach, to force the coach to take only one of two stable positions.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

La demande de brevet FR 2 917 858 décrit un commutateur électrique tel que défini ci-dessus.The patent application FR 2 917 858 discloses an electrical switch as defined above.

Dans ce document, l'élément compressible est monté mobile en translation perpendiculairement à son axe de compression de manière à être déplacé latéralement (au moyen d'un curseur solidaire de l'élément compressible) entre une position de repos, dans laquelle l'élément compressible est à l'écart de l'entraîneur (et donc inactif), et une position active, dans laquelle l'élément compressible est reçu entre une surface d'appui et l'entraîneur et contraint contre l'entraîneur.In this document, the compressible element is mounted movable in translation perpendicular to its compression axis so as to be moved laterally (by means of a slider integral with the compressible element) between a rest position, in which the element compressible is away from the trainer (and thus inactive), and an active position, in which the compressible element is received between a bearing surface and the coach and forced against the coach.

Lorsque l'élément compressible est à l'écart de l'entraîneur, le commutateur électrique fonctionne en interrupteur bistable. En revanche, lorsque l'élément compressible est situé entre la surface d'appui et l'entraîneur et est contraint contre l'entraîneur, l'élément compressible vient en appui sur l'entraîneur de manière à obliger ce dernier à prendre une seule des deux positions stables : le commutateur électrique fonctionne en bouton poussoir monostable.When the compressible element is away from the trainer, the electrical switch operates as a bistable switch. On the other hand, when the compressible element is situated between the support surface and the trainer and is forced against the trainer, the compressible element bears on the trainer so as to force him to take one of the two stable positions: the electrical switch operates as a monostable push button.

Le déplacement latéral de l'élément compressible vers sa position active, où l'élément compressible est comprimé, est toutefois délicat à mettre en oeuvre en pratique puisque le déplacement latéral nécessite de prévoir, sous l'entraîneur, une hauteur au minimum égale à l'encombrement longitudinal de l'élément compressible alors que sa compression nécessiterait de prévoir au même endroit une hauteur inférieure à son encombrement.Lateral displacement of the compressible element to its active position, where the compressible element is compressed, is however difficult to implement in practice since the lateral displacement requires the provision, under the trainer, a height at least equal to 1 longitudinal encumbrance of the compressible element while its compression would require to provide in the same place a height lower than its size.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Dans ce contexte, la présente invention propose un commutateur électrique comme défini ci-dessus, dans lequel la surface d'appui est formée sur une pièce déplaçable, selon ledit axe de compression, relativement au socle entre une position distante de l'entraîneur, dans laquelle l'élément compressible est inactif vis-à-vis de l'entraîneur, et une position d'appui, dans laquelle l'élément compressible est contraint entre la surface d'appui et l'entraîneur.In this context, the present invention proposes an electrical switch as defined above, wherein the bearing surface is formed on a movable part, along said compression axis, relative to the base between a position remote from the driver, in wherein the compressible member is inactive with respect to the driver, and a bearing position, wherein the compressible member is constrained between the bearing surface and the driver.

Ainsi le commutateur électrique peut passer de manière réversible d'un mode de fonctionnement en interrupteur bistable à un mode de fonctionnement en bouton poussoir monostable. Le passage du mode de fonctionnement en interrupteur bistable au mode de fonctionnement en bouton poussoir monostable se fait de plus aisément par déplacement, selon l'axe de compression, de la pièce portant la surface d'appui opposée à l'entraîneur et un retour au mode de fonctionnement en interrupteur bistable est possible en déplaçant cette pièce en sens inverse. Le déplacement de la surface d'appui entre les deux positions étant réalisé selon l'axe de compression, il est cohérent avec la compression de l'élément compressible dans une seule des deux positions.Thus, the electrical switch can reversibly switch from an operating mode to a bistable switch to a monostable pushbutton operating mode. The transition from the operating mode to a bistable switch to the operating mode of a monostable pushbutton is more easily done by moving, along the axis of compression, the part carrying the bearing surface opposite the driver and a return to the Bistable switch mode is possible by moving this piece in the opposite direction. Since the displacement of the bearing surface between the two positions is carried out along the axis of compression, it is consistent with the compression of the compressible element in only one of the two positions.

Sur les figures 1, 2, 5, 8, 9 et 13 ; on a représenté un commutateur électrique 100 ; 300 conforme à l'invention.On the Figures 1, 2 , 5 , 8, 9 and 13 ; an electrical switch 100 is shown; 300 according to the invention.

Ce commutateur électrique 100; 300 est destiné à être logé, par exemple après montage sur un support d'appareillage (non représenté), dans un boîtier (non représenté) destiné à être rapporté sur ou dans une paroi murale, selon un montage en saillie ou par encastrement de ce boîtier sur la paroi murale.This electrical switch 100; 300 is intended to be housed, for example after mounting on an equipment support (not shown), in a housing (not shown) intended to be mounted on or in a wall, in a projecting or recessed mounting thereof housing on the wall.

Il est alors raccordé au réseau électrique pour son alimentation.It is then connected to the electrical network for its power supply.

Dans la description, les termes « avant » et « arrière » seront utilisés par rapport à la direction du regard de l'usager vers la paroi murale sur laquelle est rapporté ce commutateur électrique 100 ; 300. Ainsi, lorsque le commutateur sera installé dans une pièce, l'avant désignera le côté tourné vers l'intérieur de la pièce et l'arrière désignera le côté tourné à l'opposé, vers l'extérieur de la pièce.In the description, the terms "front" and "rear" will be used relative to the direction of the user's gaze towards the wall on which is reported this electrical switch 100; 300. Thus, when the switch is installed in a room, the front will point to the inward side of the room and the back to the opposite side to the outside of the room.

Comme le montrent en particulier les figures 5 et 13, le commutateur électrique 100 ; 300 comporte un mécanisme de commutation logé dans un socle 110 ; 310 isolant.As shown in particular by figures 5 and 13 the electrical switch 100; 300 comprises a switching mechanism housed in a base 110; 310 insulation.

Le socle 110 ; 310 comporte un corps 112 ; 312 à partir duquel s'étend vers l'avant une paroi latérale 111 ; 311. Ce socle 110 ; 310 est ouvert à l'avant et présente un logement adapté à recevoir le mécanisme de commutation.The base 110; 310 has a body 112; 312 from which extends a side wall 111 forwards; 311. This base 110; 310 is open at the front and has a housing adapted to receive the switching mechanism.

Le corps 112 ; 312 présente une face avant 112a ; 312a qui délimite ce logement avec la face intérieure de la paroi latérale 111 ; 311. Le corps 112 ; 312 présente également une face arrière 112b; 312b à l'opposé de la face avant 112a ; 312a.The body 112; 312 has a front face 112a; 312a which delimits this housing with the inner face of the side wall 111; 311. The body 112; 312 also has a rear face 112b; 312b opposite the front face 112a; 312a.

Le mécanisme de commutation comporte un capot 120 ; 320 qui est une pièce isolante qui retient des pièces électriques conductrices logées dans le socle 110 ; 310, notamment des bornes de connexion électrique à raccorder au réseau électrique local. De manière classique, ces bornes de connexion électrique sont des bornes à connexion automatique, de sorte que chacune d'entre elles est manoeuvrable par un levier de déconnexion qui traverse une ouverture pratiquée dans la paroi du socle 110; 310 pour agir sur une lame-ressort de la borne correspondante adaptée à plaquer l'extrémité dénudée d'un conducteur électrique contre la cage de la borne de connexion. Chaque levier de déconnexion comporte une manette de commande 125 ; 325, portée par le capot 120 ; 320 et accessible à l'usager à l'extérieur dudit socle 110 ; 310.The switching mechanism comprises a cover 120; 320 which is an insulating part which holds conductive electrical parts housed in the base 110; 310, including electrical connection terminals to be connected to the local electrical network. Conventionally, these electrical connection terminals are self-connecting terminals, so that each of them is operable by a disconnect lever which passes through an opening in the wall of the base 110; 310 to act on a leaf spring of the corresponding terminal adapted to press the stripped end of an electrical conductor against the cage of the connection terminal. Each disconnect lever comprises a control lever 125; 325, carried by the hood 120; 320 and accessible to the user outside said base 110; 310.

Le capot 120 ; 320 est par exemple monté sur le socle 110 ; 310, dans la partie arrière du logement défini ci-dessus, par encliquetage, ici au moyen de pattes d'encliquetage élastiques 122; 322 formées sur le capot 120; 320 qui viennent coopérer avec des éléments complémentaires formés dans le socle 110 ; 310, par exemple des évidements 113, 313 formés dans le corps 112 du socle 110 (figure 5) ou dans la paroi latérale 311 du socle 310 (figure 13).Hood 120; 320 is for example mounted on the base 110; 310, in the rear portion of the housing defined above, by snapping, here by means of elastic snap tabs 122; 322 formed on the hood 120; 320 which cooperate with complementary elements formed in the base 110; 310, for example recesses 113, 313 formed in the body 112 of the base 110 ( figure 5 ) or in the side wall 311 of the base 310 ( figure 13 ).

Comme le montrent les figures 1, 2, 8 et 9, le mécanisme de commutation logé à l'intérieur du socle 110 ; 310 comporte également un balai 141 ; 341 adapté à basculer autour d'un axe de basculement entre deux positions extrêmes, pour mettre en contact ou hors contact un élément de contact mobile, par exemple un grain de contact mobile porté par le balai, avec au moins un élément de contact fixe, par exemple un grain de contact fixe porté par une lame de contact raccordée électriquement à l'une des bornes de connexion électrique.As shown by Figures 1, 2 , 8 and 9 the switching mechanism housed inside the base 110; 310 also includes a broom 141; 341 adapted to swing about a tilting axis between two extreme positions, to put in contact or out of contact a movable contact element, for example a movable contact bead carried by the wiper, with at least one fixed contact element, for example a fixed contact ground carried by a contact blade electrically connected to one of the electrical connection terminals.

Le mécanisme de commutation comporte également un entraîneur 130 ; 330 monté basculant sur le socle 110 ; 310 au moyen de deux pions 133 ; 333 formés sur l'entraîneur 130; 330 qui sont respectivement engagés dans deux paliers correspondants 118 ; 318 formés dans le socle 110 ; 310, par exemple au sommet de deux parties saillantes 117 du corps 112 du socle 110 (figure 5) ou dans une paroi latérale 311 du socle 310 (figure 13), réalisant ainsi un axe de basculement de l'entraîneur 130 ; 330 dans le socle 110 ; 310.The switching mechanism also includes a driver 130; 330 mounted tilting on the base 110; 310 by means of two pins 133; 333 trained on the coach 130; 330 which are respectively engaged in two corresponding bearings 118; 318 formed in the base 110; 310, for example at the top of two projections 117 of the body 112 of the base 110 ( figure 5 ) or in a side wall 311 of the base 310 ( figure 13 ), thereby providing a tilting axis of the driver 130; 330 in the base 110; 310.

L'entraîneur 130 ; 330 est une pièce isolante, réalisée par exemple en matière plastique par moulage. L'entraîneur 130 ; 330 comporte deux bras 132, 134; 332, 334, qui s'étendent respectivement de part et d'autre de l'axe de basculement, et une cheminée 136 ; 336 qui s'étend vers l'arrière, essentiellement perpendiculairement au plan formé par les bras 132,134 ; 332, 334, au niveau de l'axe de basculement, à travers une ouverture 124 ; 324 ménagée à cet effet dans le capot 120 ; 320.The coach 130; 330 is an insulating part, made for example of plastic by molding. The coach 130; 330 has two arms 132, 134; 332, 334, which extend respectively on either side of the tilt axis, and a chimney 136; 336 which extends rearward, substantially perpendicular to the plane formed by the arms 132, 134; 332, 334, at the level of the tilting axis, through an opening 124; 324 provided for this purpose in the hood 120; 320.

En effet, comme bien visible sur les figures 1, 2, 8 et 9, le capot 120 ; 320 est monté dans le logement formé dans le socle 110 ; 310 entre le corps 112 ; 312 du socle 110 ; 310 et l'entraîneur 130 ; 330.Indeed, as clearly visible on Figures 1, 2 , 8 and 9 , the hood 120; 320 is mounted in the housing formed in the base 110; 310 between the body 112; 312 of the base 110; 310 and the coach 130; 330.

Comme le montrent également les figures 1, 2, 8 et 9, le mécanisme de commutation comporte enfin des moyens élastiques de basculement 142 ; 342 (ici un ressort monté dans la cheminée 136 ; 336 formée sur l'entraîneur 130 ; 330) qui sont aptes, après franchissement d'un point dur, à solliciter le balai 141 ; 341 en direction de l'une ou de l'autre de ses positions extrêmes en fonction de la position de l'entraîneur 130 ; 330.As also shown by Figures 1, 2 , 8 and 9 the switching mechanism finally comprises elastic rocking means 142; 342 (here a spring mounted in the chimney 136; 336 formed on the coach 130; 330) which are able, after crossing a hard point, to solicit the brush 141; 341 towards one or the other of its extreme positions according to the position of the trainer 130; 330.

Ainsi, en manoeuvrant une touche (non représentée) solidaire de l'entraîneur 130; 330, l'utilisateur commande le basculement des moyens élastiques de basculement 142 ; 342, et donc du balai 141 ; 341, de sorte à mettre en contact ou hors contact l'élément de contact mobile avec l'élément de contact fixe.Thus, by operating a key (not shown) integral with the driver 130; 330, the user controls the tilting of the resilient tilting means 142; 342, and therefore of the broom 141; 341, so as to put in contact or out contact the movable contact element with the fixed contact element.

Le corps 112 ; 312 du socle 110 ; 310 présente dans une région latérale, à proximité de la paroi latérale 111 (figures 1, 2 et 5) ou au niveau de la paroi latérale 311 (figures 8, 9 et 13), un logement traversant 115 ; 315 qui reçoit une pièce 150; 350 comportant une surface d'appui 152; 352 pour un élément compressible, ici un ressort 160 ; 360, d'extension longitudinale essentiellement perpendiculaire à l'entraîneur et définissant selon cette direction d'extension longitudinale un axe de compression. Le ressort 160 ; 360 est reçu entre cette surface d'appui 152 ; 352 et un pion de centrage 138 ; 338 formé dans un bras 132 ; 332 de l'entraîneur 130 ; 330 ; précisément, le ressort 160 ; 360 est situé pour partie dans le logement traversant 115 ; 315 (à l'avant de la pièce 150 ; 350 comportant la surface d'appui 152 ; 352) et pour partie dans un espace libre formé entre la face avant 112a; 312a du corps 112; 312 du socle 110; 310 et l'entraîneur 130; 330. Le ressort 160; 360 s'étend ainsi selon son axe de compression, qui correspond à l'axe du logement traversant 115 ; 315.The body 112; 312 of the base 110; 310 has in a lateral region, near the side wall 111 ( Figures 1, 2 and 5 ) or at the side wall 311 ( Figures 8, 9 and 13 ), a through housing 115; 315 which receives a piece 150; 350 having a bearing surface 152; 352 for a compressible element, here a spring 160; 360, longitudinally extending substantially perpendicular to the driver and defining in this direction of longitudinal extension a compression axis. The spring 160; 360 is received between this bearing surface 152; 352 and a centering pin 138; 338 formed in an arm 132; 332 of the coach 130; 330; precisely, the spring 160; 360 is located partly in the through housing 115; 315 (at the front of the workpiece 150, 350 having the bearing surface 152; 352) and partly in a free space formed between the front face 112a; 312a of the body 112; 312 of the base 110; 310 and the coach 130; 330. The spring 160; 360 thus extends along its axis of compression, which corresponds to the axis of the through housing 115; 315.

Comme visible en particulier sur les figures 7 et 10, la pièce 150 ; 350 formant surface d'appui 152 ; 352 pour le ressort 160 ; 360 est de forme générale cylindrique et présente des ailettes 154 ; 354 qui s'étendent latéralement et coopèrent avec un chemin de came 116 ; 316 formé dans le corps 112 ; 312 du socle 110 ; 310 au niveau du logement traversant 115 ; 315 (voir en particulier les figures 6 et 12) de manière à arrêter la pièce 150 ; 350 vers l'arrière dans au moins deux positions (longitudinales selon l'axe du logement traversant 115, c'est-à-dire selon l'axe de compression du ressort 160 ; 360) en fonction de sa position angulaire dans le logement traversant 115 : une position distante de l'entraîneur 130 ; 330 dans laquelle le ressort 160 ; 360 (reçu, comme déjà indiqué, entre la pièce 150 ; 350 et l'entraîneur 130 ; 330) n'est pas comprimé et n'est donc pas actif, et une position d'appui dans laquelle le ressort 160 ; 360 est comprimé entre la surface d'appui 152 ; 352 et la partie arrière du bras 132 ; 332 de l'entraîneur 130 ; 330.As visible especially on figures 7 and 10 room 150; 350 forming a bearing surface 152; 352 for the spring 160; 360 is of generally cylindrical shape and has fins 154; 354 which extend laterally and cooperate with a cam path 116; 316 formed in the body 112; 312 of base 110; 310 at the through-housing 115; 315 (see in particular the figures 6 and 12 ) so as to stop the piece 150; 350 rearwards in at least two positions (longitudinal along the axis of the through housing 115, that is to say along the axis of compression of the spring 160; 360) as a function of its angular position in the housing through 115: a remote position of the trainer 130; 330 in which the spring 160; 360 (received, as already indicated, between the workpiece 150; 350 and the driver 130; 330) is not compressed and is therefore not active, and a bearing position in which the spring 160; 360 is compressed between the bearing surface 152; 352 and the rear portion of the arm 132; 332 of the coach 130; 330.

On comprend que, lorsqu'elle est dans sa position d'appui, la pièce 150 ; 350 formant surface d'appui 152 ; 352 est située plus proche de l'entraîneur 130 ; 330, c'est-à-dire vers l'avant, que lorsqu'elle est dans sa position distante.It is understood that, when in its supporting position, the piece 150; 350 forming a bearing surface 152; 352 is located closer to the trainer 130; 330, that is to say, forward, only when it is in its distant position.

Lorsque le ressort 160 ; 360 n'est pas actif, comme représenté sur les figures 1 et 8, l'entraîneur 130 ; 330 bascule librement, du fait de la commande de l'utilisateur, entre les deux positions stables, comme expliqué ci-dessus et le commutateur électrique 100 ; 300 fonctionne donc en interrupteur bistable.When the spring 160; 360 is not active, as shown on the figures 1 and 8 , the coach 130; 330 switches freely, due to the control of the user, between the two stable positions, as explained above and the electrical switch 100; 300 therefore operates as a bistable switch.

Lorsque que le ressort 160 ; 360 est actif, c'est-à-dire comme indiqué ci-dessus comprimé entre le bras 132 ; 332 de l'entraîneur 130 ; 330 et la surface d'appui 152 ; 352 de la pièce 150 ; 350, comme représenté sur les figures 2 et 9, il sollicite l'entraîneur 130 ; 330 vers une des deux positions stables en créant un moment autour de l'axe de basculement supérieur à celui généré par les moyens élastiques de basculement 142 ; 342. Par conséquent, l'entraîneur 130 ; 330 ne peut atteindre son autre position de fonctionnement (qui n'est de ce fait pas une position stable dans cette configuration) que lorsque l'utilisateur appuie sur la touche (non représentée) solidaire de l'entraîneur 130 ; 330 (et contrecarre ainsi le moment créé par le ressort 160; 360) : le commutateur électrique 100; 300 fonctionne en bouton poussoir monostable.When the spring 160; 360 is active, that is to say as indicated above compressed between the arm 132; 332 of the coach 130; 330 and the bearing surface 152; 352 of the piece 150; 350, as shown on the figures 2 and 9 he solicits the coach 130; 330 to one of two stable positions by creating a moment around the tilting axis greater than that generated by the resilient tilting means 142; 342. Therefore, the coach 130; 330 can reach its other operating position (which is not a stable position in this configuration) that when the user presses the key (not shown) integral with the trainer 130; 330 (and thus counteract the moment created by the spring 160, 360): the electrical switch 100; 300 operates as a monostable push button.

La pièce 150; 350, puis le ressort 160; 360 sont montés dans le logement traversant 115; 315 par l'avant, avant montage de l'entraîneur 130 ; 330.Room 150; 350, then the spring 160; 360 are mounted in the through housing 115; 315 from the front, before mounting the trainer 130; 330.

Le commutateur électrique 100 ; 300 comprend également un élément d'actionnement 156 ; 370 (visible en particulier sur les figures 7 et 11) adapté à commander, sur action de l'utilisateur, le déplacement de la pièce 150; 350 formant surface d'appui 152 ; 352 de sa position distante à sa position d'appui, et, réciproquement, de sa position d'appui à sa position distante.The electrical switch 100; 300 also comprises an actuating element 156; 370 (visible in particular on figures 7 and 11 ) adapted to control, on the action of the user, the movement of the part 150; 350 forming a bearing surface 152; 352 from its position remote to its support position, and reciprocally from its support position to its remote position.

Comme visible en particulier sur les figures 1, 2, 8 et 9, l'élément d'actionnement 156 ; 370 est accessible de l'arrière du commutateur 100 ; 300 par un orifice prévu dans la face arrière 112b ; 312b, ici la partie arrière du logement traversant 115 ; 315.As visible especially on Figures 1, 2 , 8 and 9 the actuating element 156; 370 is accessible from the back of the switch 100; 300 through an orifice provided in the rear face 112b; 312b, here the rear portion of the through housing 115; 315.

Ainsi, l'utilisateur (par exemple un installateur du commutateur électrique 100 ; 300) peut sélectivement placer la pièce 150 ; 350 formant surface d'appui 152; 352 dans la position distante ou dans la position d'appui, et ainsi sélectivement placer le ressort 160 ; 360 hors contact de l'entraîneur 130 ; 330, auquel cas le commutateur électrique 100; 300 fonctionne en interrupteur bistable, ou contraindre le ressort 160 ; 360 entre la surface d'appui 152 ; 352 et le bras 132 ; 332 de l'entraîneur 130 ; 330, auquel cas le commutateur électrique 100 ; 300 fonctionne en interrupteur monostable.Thus, the user (e.g., an installer of the electrical switch 100; 300) can selectively place the workpiece 150; 350 forming a bearing surface 152; 352 in the remote position or in the bearing position, and thus selectively place the spring 160; 360 off contact of the coach 130; 330, in which case the electrical switch 100; 300 operates as a bistable switch, or constrain the spring 160; 360 between the bearing surface 152; 352 and the arm 132; 332 of the coach 130; 330, in which case the electrical switch 100; 300 operates as a monostable switch.

Dans le premier mode de réalisation représenté aux figures 1 à 7, l'élément d'actionnement est un relief 156 formé dans une tête 155 de la pièce 150 et adapté à coopérer avec un outil (par exemple un tournevis). Dans le mode de réalisation décrit, la tête 155 porte également les ailettes 154 précitées, comme bien visible en figure 7.In the first embodiment shown in Figures 1 to 7 , the actuating element is a relief 156 formed in a head 155 of the workpiece 150 and adapted to cooperate with a tool (for example a screwdriver). In the embodiment described, the head 155 also carries the fins 154 above, as clearly visible in FIG. figure 7 .

Ainsi, en plaçant la lame d'un tournevis dans le relief 156, l'installateur peut entraîner en rotation la pièce 150 qui suit alors le chemin de came 116 et prend par conséquent la position distante ou la position d'appui selon sa position angulaire dans le logement traversant 115.Thus, by placing the blade of a screwdriver in the relief 156, the installer can rotate the workpiece 150 which then follows the cam path 116 and consequently takes the remote position or the support position according to its angular position. in the through housing 115.

Dans l'exemple représenté en figure 6, le chemin de came 116 comprend, de chaque côté du logement traversant 115, une rainure, une zone d'appui (située vers l'avant par rapport au fond de la rainure) et, entre la rainure et la zone d'appui, une partie intermédiaire (située vers l'avant par rapport à la zone d'appui).In the example shown in figure 6 the cam path 116 comprises, on each side of the through-housing 115, a groove, a bearing zone (located forwardly relative to the bottom of the groove) and, between the groove and the bearing zone, an intermediate part (located forward with respect to the support zone).

Lorsque les ailettes 154 sont reçues dans les rainures du chemin de came 116, la pièce 150 est en position distante et le ressort 160 n'exerce aucun effort sur le bras 132 de l'entraîneur 130, comme représenté en figure 1.When the fins 154 are received in the grooves of the cam path 116, the part 150 is remote and the spring 160 exerts no effort on the arm 132 of the driver 130, as shown in FIG. figure 1 .

Pour passer de la rainure à la zone d'appui, chaque ailette doit franchir la partie intermédiaire, ce qui n'est possible que lorsqu'un effort exercé par l'utilisateur (ici généralement l'installateur), typiquement par appui sur la tête 155 au moyen d'un tournevis, comprime le ressort 160 et fait avancer les ailettes 154 au-delà de la partie intermédiaire, ce qui autorise la rotation de la pièce 150 jusqu'à placer chaque ailette 154 au droit de la zone d'appui. Le passage de la pièce 150 de la position distante à la position d'appui n'est ainsi possible que par choix de l'installateur, et ne peut se réaliser de manière inopinée. La pièce atteint alors sa position d'appui représentée en figure 2.To move from the groove to the support zone, each fin must cross the intermediate part, which is possible only when a force exerted by the user (here usually the installer), typically by pressing on the head 155 by means of a screwdriver, compresses the spring 160 and advances the fins 154 beyond the intermediate portion, which allows the rotation of the piece 150 to place each fin 154 to the right of the support zone. The passage of the part 150 from the remote position to the support position is thus possible only by choice of the installer, and can not be performed unexpectedly. The piece then reaches its support position represented in figure 2 .

De même, lorsque l'installateur souhaite ramener la pièce 150 de la position d'appui (dans laquelle le ressort 160 est contraint entre la surface d'appui 152 de la pièce 150 et le bras 132 de l'entraîneur 130) à la position distante, il exerce (au moyen d'un tournevis, à travers la partie arrière du logement traversant 115) un effort vers l'avant sur la pièce 150, ce qui comprime un peu plus le ressort 160 et permet de faire avancer chaque ailette 154 au-delà de la partie intermédiaire du chemin de came 116 ; la pièce 150 peut alors être entraînée en rotation par le tournevis de sorte que chaque ailette 154 regagne la rainure du chemin de came (ce qui correspond à la position distante de la pièce 150).Similarly, when the installer wishes to bring the part 150 of the support position (in which the spring 160 is constrained between the bearing surface 152 of the part 150 and the arm 132 of the driver 130) to the position remote, it exerts (by means of a screwdriver, through the rear portion of the through housing 115) a forward force on the part 150, which compresses a little more spring 160 and allows to advance each fin 154 beyond the intermediate portion of the cam path 116; the part 150 can then be rotated by the screwdriver so that each fin 154 regains the groove of the cam path (which corresponds to the position distant from the part 150).

Dans le second mode de réalisation représenté aux figures 8 à 13, l'élément d'actionnement est un bouchon 370 monté dans la partie arrière du logement traversant 315 et qui entraîne la pièce 350 portant la surface d'appui 352 en rotation (et donc en translation entre la position distante et la position d'appui grâce au chemin de came 316) lorsqu'il est déplacé vers l'avant par l'utilisateur (ici l'installateur), comme expliqué à présent.In the second embodiment shown in Figures 8 to 13 , the actuating element is a plug 370 mounted in the rear portion of the through housing 315 and which drives the workpiece 350 carrying the bearing surface 352 in rotation (and thus in translation between the remote position and the support position thanks to the cam path 316) when it is moved forward by the user (here the installer), as explained now.

Comme montré en figure 11, le bouchon 370 est de forme générale cylindrique et comprend une pluralité de plots 372 (ici 8 plots) en saillie de sa surface latérale et équirépartis sur la circonférence du bouchon 370. On remarque que l'encombrement latéral du bouchon 370 au niveau des plots 372 est inférieur à l'encombrement latéral de la pièce 350 au niveau des ailettes 354. Par ailleurs, le nombre de plots 372 (ici 8) est le double du nombre d'ailettes 354 (ici 4).As shown in figure 11 , the plug 370 is generally cylindrical in shape and comprises a plurality of studs 372 (here 8 studs) projecting from its lateral surface and equidistributed around the circumference of the cap 370. It is noted that the lateral size of the cap 370 at the level of the studs 372 is less than the lateral size of the part 350 at the fins 354. Moreover, the number of pads 372 (here 8) is twice the number of fins 354 (here 4).

Le bouchon 370 comporte également un évidement central 376 (de forme cylindrique de même axe que le bouchon 370) destiné à recevoir une partie complémentaire cylindrique 356 de la pièce 350 formant surface d'appui 352.The plug 370 also comprises a central recess 376 (of cylindrical shape with the same axis as the plug 370) intended to receive a cylindrical complementary portion 356 of the part 350 forming a bearing surface 352.

Le bouchon comprend enfin, sur une partie avant entourant l'évidement central 376, une pluralité de pans inclinés 374 destinés à coopérer comme expliqué ci-après avec des surfaces d'extrémité inclinées 358 des ailettes 354 de la pièce 350.The cap finally comprises, on a front portion surrounding the central recess 376, a plurality of inclined faces 374 intended to cooperate as explained hereinafter with inclined end surfaces 358 of the fins 354 of the part 350.

Comme représenté sur la figure 12, la surface intérieure du logement traversant 315 présente une pluralité de reliefs longitudinaux 319 (en nombre égal aux plots 372 du bouchon 370, soit ici 8 reliefs longitudinaux) qui définissent entre eux autant de rainures longitudinales 314 adaptées à recevoir les plots 372 du bouchon 370, jusqu'à une butée arrière, ainsi que les ailettes 354 de la pièce 350.As shown on the figure 12 , the inner surface of the through housing 315 has a plurality of longitudinal projections 319 (in number equal to the pads 372 of the cap 370, here 8 longitudinal projections) which define between them as many longitudinal grooves 314 adapted to receive the pads 372 of the plug 370 up to a rear stop, as well as the fins 354 of the workpiece 350.

Une rainure 314 sur deux (soit ici 4 rainures) est par ailleurs partiellement remplie par un élément de butée 317 conçu pour ménager un espace suffisant dans la rainure 314 pour accueillir un plot 372 sur toute la longueur de la rainure 314 et pour former butée, à l'avant de l'élément de butée 317, pour une ailette 354 de la pièce 350 formant surface d'appui 352.A groove 314 of two (here 4 grooves) is also partially filled by a stop element 317 designed to provide sufficient space in the groove 314 to accommodate a stud 372 over the entire length of the groove 314 and to form a stop, at the front of the abutment element 317, for a fin 354 of the part 350 forming a bearing surface 352.

Lorsque la pièce 150 est dans sa position distante (dans laquelle le ressort 360 n'est pas comprimé et le commutateur 300 fonctionne donc en interrupteur bistable), comme représenté en figure 8, les ailettes 354 sont chacune reçues dans une rainure 314 sans élément de butée.When the piece 150 is in its remote position (in which the spring 360 is not compressed and the switch 300 thus operates as a bistable switch), as shown in FIG. figure 8 the fins 354 are each received in a groove 314 without abutment member.

L'installateur peut alors enfoncer le bouchon 370 vers l'avant, lequel bouchon entraîne alors la pièce 350 formant surface d'appui 352 vers l'avant, ce qui entraîne la compression du ressort (comme représenté en figure 9). Ce mouvement de pure translation de la pièce 350 (du fait de l'engagement des ailettes 354 dans les rainures 314) se poursuit jusqu'à ce que chaque ailette 354 sorte de sa rainure 314, ce qui autorise la rotation de la pièce 350 sur elle-même.The installer can then push the cap 370 forwards, which plug then drives the piece 350 forming a bearing surface 352 forwards, which causes the compression of the spring (as shown in FIG. figure 9 ). This movement of pure translation of the workpiece 350 (due to the engagement of the fins 354 in the grooves 314) continues until each fin 354 leaves its groove 314, which allows the rotation of the workpiece 350 on herself.

Grâce à la coopération des pans inclinés 374 du bouchon 370 et des surfaces d'extrémité inclinées 358 des ailettes 354, la poursuite de la translation du bouchon 370 vers l'avant (toujours du fait de l'effort exercé par l'installateur) provoque effectivement la rotation de la pièce 350 jusqu'à ce qu'elle se trouve au droit de la rainure suivante (qui est donc, conformément à la description donnée plus haut, une rainure 314 pourvu d'un élément de butée 317).Thanks to the cooperation of the inclined faces 374 of the plug 370 and the inclined end surfaces 358 of the fins 354, the further translation of the plug 370 forwards (still due to the effort exerted by the installer) causes effectively the rotation of the workpiece 350 until it is in line with the next groove (which is, according to the description given above, a groove 314 provided with a stop member 317).

Par conséquent, lorsque l'installateur relâche son effort sur le bouchon 370, la pièce 350 est entraînée en translation vers l'arrière du fait de la compression du ressort 360, jusqu'à ce que chaque ailette 354 vienne en butée contre la partie avant de l'élément formant butée 317 : la pièce 350 est dans sa position d'appui, dans laquelle le ressort 360 est contraint entre la surface d'appui 352 et le bras de l'entraîneur 332 et le commutateur fonctionne en interrupteur monostable.Therefore, when the installer releases his effort on the plug 370, the part 350 is driven in translation towards the rear because of the compression of the spring 360, until each fin 354 abuts against the front part of the abutment member 317: the workpiece 350 is in its bearing position, in which the spring 360 is constrained between the bearing surface 352 and the arm of the driver 332 and the switch operates as a monostable switch.

L'installateur (ou tout autre utilisateur) peut alors à tout moment enfoncer à nouveau le bouchon 370, ce qui fait sortir chaque ailette 354 de la rainure 314 (avec élément de butée 317) qui la reçoit et permet ainsi la rotation de la pièce 350 par coopération des pans inclinés 374 et des surfaces d'extrémité inclinées 358, jusqu'à ce que chaque ailette 354 se trouve au droit d'une rainure 314 sans élément de butée : le relâchement de l'effort sur le bouchon 370 par l'installateur provoquera alors le retour de la pièce 350 dans sa position distante, dans laquelle le ressort 360 n'est pas comprimé et le commutateur électrique 300 fonctionne en interrupteur bistable.The installer (or any other user) can then at any time again the plug 370, which causes each fin 354 to exit the groove 314 (with abutment element 317) which receives it and thus allows the rotation of the workpiece 350 by cooperation of the inclined faces 374 and the inclined end surfaces 358 , until each fin 354 is in line with a groove 314 without abutment element: the release of the force on the plug 370 by the installer will then cause the return of the workpiece 350 to its remote position, wherein the spring 360 is not compressed and the electrical switch 300 operates as a bistable switch.

On peut ainsi basculer autant de fois que nécessaire entre les modes de fonctionnement interrupteur bistable et bouton poussoir monostable par simple enfoncement du bouchon 370 dans le logement traversant 315.It is thus possible to switch as many times as necessary between the operating modes of the bistable switch and the one-shot pushbutton by simply depressing the plug 370 in the through-housing 315.
