L'éclairage permanent permet d'indiquer à un utilisateur la position d'un tel appareillage de commutation dans la pénombre.There are already various switching devices of the aforementioned type in which the lighting device includes an indicator light which permanently illuminates the facade of the device. Permanent lighting makes it possible to indicate to a user the position of such switching equipment in the dark.

Parmi les appareillages de commutation déjà connus, il y a ceux qui comprennent un voyant placé dans une région centrale, juste en dessous de la touche de commande. Ce voyant éclaire la façade de la touche de commande au travers de petites ouvertures prévues dans la touche de commande. Il y a également ceux qui comprennent plusieurs voyants disposés sur des bords de l'appareillage. Dans certains appareillages de commutation déjà connus, il est prévu un guide de lumière qui permet de former un halo lumineux autour de la touche de commande.Among the already known switchgears are those which include an indicator light placed in a central region, just below the control key. This light illuminates the front of the control key through small openings provided in the control key. There are also those which include several indicator lights arranged on the edges of the equipment. In certain already known switching devices, a light guide is provided which makes it possible to form a luminous halo around the control key.

En particulier, le document DE4416273 décrit un interrupteur étanche qui comporte deux sources de lumière enfermées dans un boîtier, sous une paroi frontale. Au droit de chaque source de lumière, il est prévu une paroi transparente incurvée au travers de laquelle la source de lumière émet un flux lumineux en direction d'une touche de commande. Selon ce document, les flux lumineux émis par les sources de lumière traversent la touche de commande pour éclairer la face avant de cette touche de commande. L'une des sources de lumière, dite source fonctionnelle, émet un flux lumineux à travers un guide de lumière attaché à la touche de commande alors que l'autre source de lumière, dite source de positionnement, émet un flux lumineux à travers une fenêtre de la touche de commande. Dans une seule des deux positions de basculement de la touche de commande, la position ON, une extrémité du guide de lumière recouvre la paroi transparente incurvée chapeautant ladite source de lumière dite fonctionnelle. En revanche, quelle que soit la position de basculement de la touche de commande, la source de lumière, dite source de positionnement, éclaire la face avant de la touche de commande au travers de la fenêtre pour indiquer à un utilisateur la position de l'interrupteur sur la paroi de réception.In particular, the document DE4416273 describes a waterproof switch which has two light sources enclosed in a housing, under a front wall. To the right of each light source, there is provided a curved transparent wall through which the light source emits a luminous flux towards a control key. According to this document, the luminous fluxes emitted by the light sources pass through the control key to illuminate the front face of this control key. One of the light sources, called the functional source, emits a luminous flux through a light guide attached to the control key while the other light source, called the positioning source, emits a luminous flux through a window of the control key. In only one of the two tilting positions of the control key, the ON position, one end of the light guide covers the curved transparent wall covering said so-called functional light source. On the other hand, whatever the tilting position of the control key, the light source, called the positioning source, illuminates the front face of the control key through the window to indicate to a user the position of the control key. switch on the reception wall.

Le document GB1166508 décrit un commutateur qui comprend une touche de commande montée basculante dans un boîtier. Il est ici prévu une source de lumière disposée dans une partie du boîtier, sur un côté de la touche de commande. Une partie du flux lumineux émis par la source de lumière est dirigée vers la touche de commande. La touche de commande comporte une fenêtre qui, dans une seule position de basculement de la touche de commande, la position ON, se place en regard de la source de lumière pour autoriser le flux lumineux émis par la source de lumière à traverser la touche de commande pour éclairer le symbole placé sur la face avant de la touche. Dans l'autre position de basculement de la touche de commande, la position OFF, la base et le bord opaques de la touche de commande se positionnent en face de la source de lumière de sorte que le flux lumineux émis par la source de lumière en direction de la touche de commande ne peut pas pénétrer dans ladite touche et le symbole n'est pas éclairé.The document GB1166508 describes a switch which includes a control button tiltably mounted in a housing. A light source is provided here arranged in part of the housing, on one side of the control button. Part of the luminous flux emitted by the light source is directed towards the control button. The control key includes a window which, in a single tilting position of the control key, the ON position, is placed opposite the light source to allow the luminous flux emitted by the light source to pass through the control key. command to illuminate the symbol placed on the front of the key. In the other tilting position of the control key, the OFF position, the opaque base and edge of the control key are positioned opposite the light source so that the luminous flux emitted by the light source in direction of the control key cannot enter said key and the symbol is not illuminated.

Les deux documents DE4416273 et GB1166508 proposent un enseignement similaire selon lequel la touche de commande est agencée (soit avec un guide de lumière soit avec une fenêtre) pour que dans une seule position de basculement de la touche de commande, une source de lumière placée dans le boîtier de l'interrupteur soit capable d'émettre au travers de la touche de commande un flux lumineux qui illumine une face avant de cette touche.The two documents DE4416273 And GB1166508 propose a similar teaching according to which the control key is arranged (either with a light guide or with a window) so that in a single tilting position of the control key, a light source placed in the switch housing is capable of emitting through the control key a luminous flux which illuminates a front face of this key.

Par rapport aux agencements déjà connus, la présente invention propose un nouvel appareillage de commutation dont l'agencement permet d'éclairer en alternance deux zones distinctes déterminées de la façade de l'appareillage pour indiquer, notamment dans la pénombre, l'endroit précis de la touche de commande où le doigt d'un utilisateur doit appuyer pour faire basculer la touche de commande afin de commander la commutation du mécanisme de l'appareillage de commutation.Compared to the arrangements already known, the present invention proposes a new switching device whose arrangement makes it possible to alternately illuminate two specific distinct zones of the facade of the device to indicate, particularly in the dark, the precise location of the control key where a user's finger must press to toggle the control key to control the switching of the switchgear mechanism.

Plus particulièrement, la présente invention propose un appareillage de commutation tel que défini dans la revendication 1.More particularly, the present invention provides switching equipment as defined in claim 1.

D'autres caractéristiques de l'appareillage de commutation conforme à l'invention sont décrites dans les revendications 2 à 11.Other characteristics of the switching equipment according to the invention are described in claims 2 to 11.

Dans la description qui va suivre, les termes avant et arrière seront définis par rapport au regard d'un utilisateur, l'avant d'un élément de l'invention étant tourné vers l'utilisateur tandis que l'arrière de cet élément est tourné à l'opposé de l'utilisateur.In the description which follows, the terms front and rear will be defined in relation to the gaze of a user, the front of an element of the invention being turned towards the user while the rear of this element is turned away from the user.

Sur les figures 1 à 3, on a représenté un ensemble électrique monoposte qui comporte un mode de réalisation préférentiel d'un appareillage de commutation 1 monoposte conforme à l'invention et une plaque de finition 50 rapportée sur l'appareillage de commutation 1. Sur les figures 19 et 20, on a représenté une légère variante de ce mode de réalisation préférentiel de l'appareillage de commutation 1.On the figures 1 to 3 , there is shown a single-station electrical assembly which comprises a preferred embodiment of a single-station switching device 1 according to the invention and a finishing plate 50 attached to the switchgear 1. On the figures 19 and 20 , a slight variation of this preferred embodiment of the switching equipment 1 has been shown.

Selon ce mode de réalisation préférentiel, l'appareillage de commutation 1 comprend :

  • un boîtier 10 qui loge un mécanisme d'appareillage,
  • un support d'appareillage 20 qui forme une seule pièce monobloc avec ledit boîtier 10,
  • une touche de commande 30 du mécanisme d'appareillage,
  • un enjoliveur 40 rapporté à l'avant dudit boîtier 10, sur une partie fixe 18 de celui-ci, et
  • un dispositif d'éclairage comprenant deux sources de lumière 112 appartenant à deux voyants 100 distincts, connectés électriquement l'un à l'autre par un conducteur électrique 101 et alimentés en courant via ledit mécanisme d'appareillage.
According to this preferred embodiment, the switching equipment 1 comprises:
  • a housing 10 which houses an equipment mechanism,
  • an equipment support 20 which forms a single, single piece with said housing 10,
  • a control key 30 of the equipment mechanism,
  • a hubcap 40 attached to the front of said housing 10, on a fixed part 18 thereof, and
  • a lighting device comprising two light sources 112 belonging to two separate indicator lights 100, electrically connected to each other by an electrical conductor 101 and supplied with current via said equipment mechanism.

Le boîtier 10 et le support d'appareillage 20 sont réalisés d'une seule pièce par moulage d'un polymère thermoplastique rigide comme un ABS (Acrylonitrile Butadiène Styrène).The housing 10 and the equipment support 20 are made in one piece by molding a rigid thermoplastic polymer such as ABS (Acrylonitrile Butadiene Styrene).

Comme le montrent plus particulièrement les figures 1 et 3 à 5, le boîtier 10 comporte ici une paroi de fond 19 et une paroi latérale 11 délimitant un volume intérieur globalement parallélépipédique ouvert à l'avant (voir figure 1).As shown more particularly by the figures 1 And 3 to 5 , the housing 10 here comprises a bottom wall 19 and a side wall 11 delimiting a generally parallelepiped interior volume open at the front (see figure 1 ).

La paroi de fond 19 comporte des ouvertures 19A pour l'entrée dans le boîtier 10 d'une partie dénudée de conducteurs d'alimentation électrique (non représentés) provenant du réseau électrique, en vue de leur raccordement aux bornes de connexion BC du mécanisme d'appareillage (voir figures 4 et 6).The bottom wall 19 has openings 19A for the entry into the housing 10 of a stripped part of electrical supply conductors (not shown) coming from the electrical network, with a view to their connection to the connection terminals BC of the mechanism d equipment (see figures 4 And 6 ).

Le support d'appareillage 20 se présente sous la forme d'une plaque dont le bord extérieur 21 suit un contour carré (voir figures 1, 4, 5 et 16). Cette plaque située à l'avant du boîtier 10, entoure ledit boîtier 10 et s'étend en porte-à-faux de la paroi latérale 11 du boîtier 10, perpendiculairement à celle-ci (voir figures 4 et 5).The equipment support 20 is in the form of a plate whose outer edge 21 follows a square contour (see figures 1 , 4 , 5 And 16 ). This plate located at the front of the housing 10, surrounds said housing 10 and extends overhanging the side wall 11 of the housing 10, perpendicular to it (see figures 4 and 5 ).

Le support d'appareillage 20 comporte une face avant 20A et une face arrière 20B opposées. La face arrière 20B s'étend dans un plan tandis que la face avant 20A est une surface légèrement bombée (voir figures 5 et 20).The equipment support 20 has an opposite front face 20A and a rear face 20B. The rear face 20B extends in a plane while the front face 20A is a slightly convex surface (see figures 5 And 20 ).

La paroi latérale 11 du boîtier 10 s'étend vers l'arrière à partir de la face arrière 20B du support d'appareillage 20, globalement perpendiculairement à cette face arrière 20B (voir figures 4 et 5). L'ouverture avant du boîtier 10 est délimitée par un bord 22 à partir duquel s'étend la face avant 20A du support d'appareillage 20.The side wall 11 of the housing 10 extends rearwardly from the rear face 20B of the equipment support 20, generally perpendicular to this rear face 20B (see figures 4 and 5 ). The front opening of the housing 10 is delimited by an edge 22 from which the front face 20A of the equipment support 20 extends.

Le support d'appareillage 20 comporte une partie plane 23 (c'est-à-dire une partie définie entre deux plans parallèles) présentant quatre portions disposées aux quatre points cardinaux, le long du bord 22 de l'ouverture avant du boîtier 10 (voir figures 1 et 16). La face arrière 23B de cette partie plane 23 appartient à la face arrière 20B plane dudit support d'appareillage 20 (voir figure 4) et la face avant 23A plane de cette partie plane 23 est placée en léger retrait par rapport à la face avant 20A bombée dudit support d'appareillage 20 (voir figures 1, 16, 17 et 19). La face avant 23A de cette partie plane 23 est délimitée par un rebord 23C formé par un décrochement de la face avant 20A du support d'appareillage 20 (voir figures 1 et 16).The equipment support 20 comprises a flat part 23 (that is to say a part defined between two parallel planes) having four portions arranged at the four cardinal points, along the edge 22 of the front opening of the housing 10 ( see figures 1 And 16 ). The rear face 23B of this flat part 23 belongs to the flat rear face 20B of said equipment support 20 (see figure 4 ) and the flat front face 23A of this flat part 23 is placed slightly set back relative to the curved front face 20A of said equipment support 20 (see figures 1 , 16 , 17 And 19 ). The front face 23A of this flat part 23 is delimited by a rim 23C formed by a recess of the front face 20A of the equipment support 20 (see figures 1 And 16 ).

Comme le montrent les figures 1, 16, 17 et 19, le support d'appareillage 20 comporte quatre ouvertures 25 traversantes. Ces quatre ouvertures 25 sont disposées sur deux axes X, Y perpendiculaires et se coupant au point d'intersection O situé au centre de l'ouverture avant du boîtier 10. Elles sont deux à deux opposées. Les ouvertures 25 traversent la partie plane 23 du support d'appareillage 20. Elles présentent une forme de trou de serrure et servent à la fixation par vis du support d'appareillage 20 à une boîte d'encastrement (non représentée).As shown in the figures 1 , 16 , 17 And 19 , the equipment support 20 has four through openings 25. These four openings 25 are arranged on two perpendicular axes The openings 25 pass through the flat part 23 of the equipment support 20. They have a keyhole shape and are used for fixing the equipment support 20 by screw to a flush-mounting box (not shown).

Le support d'appareillage 20 comporte également des fentes 26 d'encliquetage de dents (non visibles sur les figures) prévues sur la face arrière de la plaque de finition 50.The equipment support 20 also includes tooth latching slots 26 (not visible in the figures) provided on the rear face of the finishing plate 50.

La plaque de finition 50 représentée sur les figures 1 à 3 est un exemple de plaque pouvant être montée sur le support d'appareillage 20, autour de la touche de commande 30 de l'appareillage de commutation 1, pour parfaire la finition de l'ensemble électrique. Cette plaque de finition 50 ne fait pas partie de la présente invention. Elle recouvre la face avant 20A du support d'appareillage 20 en débordant du bord extérieur 21 de celui-ci pour prendre appui contre la paroi de réception (non représentée). Ici, elle présente un contour extérieur 52 carré et une ouverture centrale 51 dont le bord 51A est circulaire.The finishing plate 50 shown on the figures 1 to 3 is an example of a plate that can be mounted on the equipment support 20, around the control button 30 of the switching equipment 1, to perfect the finish of the electrical assembly. This finishing plate 50 is not part of the present invention. It covers the front face 20A of the equipment support 20, extending beyond the outer edge 21 of the latter to bear against the receiving wall (not shown). Here, it has a square outer contour 52 and a central opening 51 whose edge 51A is circular.

Comme le montre plus particulièrement la figure 2, lorsque la plaque de finition 50 est rapportée sur ledit support d'appareillage 20, l'enjoliveur 40 de l'appareillage de commutation 1 émerge dans l'ouverture centrale 51 de la plaque de finition 50 et un interstice annulaire A est formé entre le bord extérieur 41 circulaire de l'enjoliveur 40 et le bord 51A circulaire intérieur de la plaque enjoliveur 50. La touche de commande 30 de forme annulaire est placée dans cet interstice annulaire A de sorte que son bord intérieur 30C longe le bord extérieur 41 de l'enjoliveur 40 et que son bord extérieur 30D longe le bord 51A intérieur de la plaque enjoliveur 50. La face avant 50A de cette plaque de finition 50 s'étend sensiblement dans le même plan que la face avant 40A dudit enjoliveur 40.As shown more particularly by figure 2 , when the finishing plate 50 is attached to said equipment support 20, the hubcap 40 of the switching gear 1 emerges in the central opening 51 of the finishing plate 50 and an annular gap A is formed between the outer circular edge 41 of the hubcap 40 and the inner circular edge 51A of the hubcap plate 50. The control key 30 of annular shape is placed in this annular gap A so that its inner edge 30C runs along the outer edge 41 of the hubcap 40 and its outer edge 30D runs along the inner edge 51A of the hubcap plate 50. The front face 50A of this finishing plate 50 extends substantially in the same plane as the front face 40A of said hubcap 40.

Comme le montrent les figures 1, 16, 18 et 20, le mécanisme d'appareillage logé dans le boîtier 10 comprend un entraîneur 15 monté à basculement dans le boîtier 10 et comprenant un fût 15D qui attrape une partie de basculement d'un balai mobile B en appui contre une chape C1 et enfilé dans un ressort (non visible) logé dans ledit fût 15D. L'entraîneur 15 est adapté à déplacer ledit balai mobile B pourvu d'un grain de contact, entre une position de fermeture dans laquelle ledit grain de contact est en appui contre un grain de contact fixe (non représenté) et une position d'ouverture dans laquelle ledit grain de contact est éloigné dudit grain de contact fixe.As shown in the figures 1 , 16 , 18 And 20 , the equipment mechanism housed in the housing 10 comprises a driver 15 mounted for tilting in the housing 10 and comprising a barrel 15D which catches a tilting part of a movable broom B resting against a yoke C1 and threaded into a spring (not visible) housed in said 15D barrel. The driver 15 is adapted to move said movable brush B provided with a contact grain, between a closed position in which said contact grain bears against a fixed contact grain (not shown) and an open position in which said contact grain is distant from said fixed contact grain.

Le mécanisme d'appareillage comprend également, dans le fond du boîtier 10, des bornes de connexion électrique BC (voir figure 6) connectées à la chape ainsi qu'au grain de contact fixe. Ici, il est prévu par exemple quatre bornes de connexion électrique BC pour la connexion du mécanisme de commutation. Ces bornes de connexion électrique BC sont par exemple 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 latérale 11 du boîtier 10 pour agir sur la lame-ressort de la borne correspondante. Chaque levier de déconnexion comporte une manette de commande 17 accessible à l'usager à l'extérieur dudit boîtier 10 (voir figures 1, 3, 18 et 20).The equipment mechanism also includes, in the bottom of the housing 10, electrical connection terminals BC (see Figure 6 ) connected to the screed as well as to the fixed contact grain. Here, for example, four electrical connection terminals BC are provided for connecting the switching mechanism. These electrical connection terminals BC are for example automatic connection terminals, so that each of them can be operated by a disconnection lever which passes through an opening made in the side wall 11 of the housing 10 to act on the leaf spring of the corresponding terminal. Each disconnection lever includes a control lever 17 accessible to the user outside said housing 10 (see figures 1 , 3 , 18 And 20 ).

Comme le montrent les figures 1, 16 et 19, l'entraîneur 15 comporte une partie supérieure se présentant sous la forme d'un berceau disposé entre deux parois 18 fixes et parallèles du boîtier 10. Ces deux parois 18 émergent au-dessus de la face avant 20A du support d'appareillage 20 (voir figure 5) et elles comprennent dans les parties émergentes au-dessus dudit support d'appareillage 20 deux paliers 18A dont les axes sont alignés sur l'axe Y dit axe de basculement. Ces deux paliers 18A accueillent deux tourillons portés par deux faces externes longitudinales du berceau de sorte que l'entraîneur 15 peut pivoter autour de l'axe de basculement Y. Deux extrémités opposées du berceau de l'entraîneur 15 sont agencées pour l'accrochage de la touche de commande 30. Chacune de ces extrémités opposées du berceau de l'entraîneur 15 comporte, pour l'accrochage de la touche de commande 30, une dent 15B encadrée par deux décrochés 15C prévus dans les deux faces externes longitudinales du berceau et deux plateformes 15A (voir figures 1, 16, 19 et 20).As shown in the figures 1 , 16 And 19 , the driver 15 comprises an upper part in the form of a cradle disposed between two fixed and parallel walls 18 of the housing 10. These two walls 18 emerge above the front face 20A of the equipment support 20 ( see Figure 5 ) and they comprise in the emerging parts above said equipment support 20 two bearings 18A whose axes are aligned with the Y axis called the tilting axis. These two bearings 18A accommodate two pins carried by two longitudinal external faces of the cradle so that the driver 15 can pivot around the tilting axis Y. Two opposite ends of the cradle of the driver 15 are arranged for the attachment of the control key 30. Each of these opposite ends of the cradle of the driver 15 comprises, for the attachment of the control key 30, a tooth 15B framed by two unhooks 15C provided in the two longitudinal external faces of the cradle and two 15A platforms (see figures 1 , 16 , 19 and 20 ).

La touche de commande 30 est avantageusement réalisée (voir figure 18) par assemblage de deux pièces annulaires clipsées entre elles, chacune réalisée par moulage d'un polymère thermoplastique tel que l'ABS (l'Acrylonitrile Butadiène Styrène).The control key 30 is advantageously produced (see Figure 18 ) by assembling two annular parts clipped together, each made by molding a thermoplastic polymer such as ABS (Acrylonitrile Butadiene Styrene).

Comme le montrent les figures 1, et 12 à 15, la touche commande 30 présente la forme d'un anneau dont le bord intérieur 30C délimite une ouverture circulaire 30E. Cet anneau 30 présente une face avant 30A légèrement concave et, à l'opposé de la face avant 30A, une face arrière 30B plane. La face avant 30A forme la face d'appui d'un doigt d'un utilisateur. Pour le montage de la touche de commande 30 sur le berceau de l'entraîneur 15, la face arrière 30B de la touche de commande 30 porte deux barreaux 31 parallèles qui s'étendent selon deux cordes de l'ouverture circulaire 30E. La distance entre les barreaux 31 est égale à la longueur du berceau de l'entraîneur 15 de sorte que lesdits barreaux 31 sont adaptés à coopérer avec les agencements prévus à cet effet à chaque extrémité dudit berceau. Pour coopérer avec le berceau de l'entraîneur 15, chaque barreau 31 comporte au centre d'une face longitudinale 31A tournée vers l'autre barreau 31, une dent 31C encadrée par deux montants 31E parallèles. Enfin, le bord intérieur 30C de la touche de commande 30 porte deux plots 32 qui s'étendent l'un vers l'autre selon un diamètre D de l'ouverture circulaire 30E (voir figure 14). Chaque plot 32 présente une face arrière 32B en forme de coin en creux dont le sommet 32C est une arête s'étendant selon ledit diamètre D. Comme le montrent plus particulièrement les figures 1 et 16, il est prévu en correspondance dans l'ouverture avant du boîtier 10, deux chapes 16 présentant une forme en coin en saillie dont les sommets sont alignés sur l'axe de basculement Y.As shown in the figures 1 , And 12 to 15 , the control key 30 has the shape of a ring whose inner edge 30C delimits a circular opening 30E. This ring 30 has a slightly concave front face 30A and, opposite the front face 30A, a flat rear face 30B. The front face 30A forms the support face of a user's finger. For mounting the control key 30 on the cradle of the trainer 15, the rear face 30B of the control key 30 carries two parallel bars 31 which extend along two chords of the circular opening 30E. The distance between the bars 31 is equal to the length of the cradle of the driver 15 so that said bars 31 are adapted to cooperate with the arrangements provided for this purpose at each end of said cradle. To cooperate with the cradle of the driver 15, each bar 31 has in the center of a longitudinal face 31A facing the other bar 31, a tooth 31C framed by two parallel uprights 31E. Finally, the inner edge 30C of the control key 30 carries two studs 32 which extend towards each other along a diameter D of the circular opening 30E (see Figure 14 ). Each stud 32 has a rear face 32B in the shape of a recessed wedge, the top 32C of which is an edge extending along said diameter D. As shown more particularly in the figures 1 And 16 , there are correspondingly provided in the front opening of the housing 10, two yokes 16 having a projecting corner shape whose vertices are aligned with the tilting axis Y.

Comme le montrent les figures 18 à 20, la touche de commande 30 est solidarisée au berceau de l'entraîneur 15 par l'accrochage des dents 31C des barreaux 31 de ladite touche aux dents 15B du berceau de l'entraîneur 15. De manière concomitante à cet accrochage, les montants 31E portés par lesdits barreaux 31 se placent dans les décrochés 15C prévus dans les deux faces externes longitudinales du berceau et les faces arrière 31B desdits barreaux 31 reposent sur les plateformes 15A du berceau de l'entraîneur 15. De cette manière, la touche de commande 30 est bloquée sur ledit berceau de l'entraîneur 15 selon les trois directions spatiales perpendiculaires X, Y et Z (voir figure 19).As shown in the figures 18 to 20 , the control key 30 is secured to the cradle of the driver 15 by the attachment of the teeth 31C of the bars 31 of said button to the teeth 15B of the cradle of the driver 15. Concomitantly with this attachment, the uprights 31E carried by said bars 31 are placed in the recesses 15C provided in the two longitudinal external faces of the cradle and the rear faces 31B of said bars 31 rest on the platforms 15A of the cradle of the coach 15. In this way, the control key 30 is blocked on said cradle of the trainer 15 in the three perpendicular spatial directions X, Y and Z (see Figure 19 ).

Ainsi, l'appui d'un doigt sur la touche de commande 30 permet de faire basculer l'entraîneur 15 autour de l'axe de basculement Y qui déplace le balai mobile B.Thus, pressing a finger on the control key 30 makes it possible to tilt the driver 15 around the tilting axis Y which moves the movable broom B.

Comme le montrent plus particulièrement les figures 17 à 20, lorsque la touche de commande 30 est rapportée sur le berceau de l'entraîneur 15, elle s'étend au-dessus du support d'appareillage 20 en recouvrant une partie annulaire de la face avant 23A de la partie plane 23 dudit support d'appareillage 20. Elle est apte à basculer autour de l'axe de basculement Y entre deux positions angulaires distinctes par rapport à ladite partie plane 23 située en dessous d'elle. Les deux positions angulaires distinctes de la touche de commande 30 correspondent à deux positions de commutation de l'entraîneur 15. Ici, les deux positions angulaires de la touche de commande 30 sont deux positions stables. En variante, on pourrait prévoir qu'il n'y ait qu'une position stable de la touche de commande (il faudrait pour cela prévoir dans le boîtier un moyen de rappel qui pousse en permanence la touche commande vers sa position angulaire stable) celle-ci fonctionnant comme un bouton poussoir.As shown more particularly by the figures 17 to 20 , when the control key 30 is attached to the cradle of the trainer 15, it extends above the equipment support 20 by covering an annular part of the front face 23A of the flat part 23 of said equipment support 20. It is capable of tilting around the tilting axis Y between two distinct angular positions relative to said part plane 23 located below it. The two distinct angular positions of the control key 30 correspond to two switching positions of the driver 15. Here, the two angular positions of the control key 30 are two stable positions. Alternatively, it could be provided that there is only one stable position of the control key (for this it would be necessary to provide in the housing a return means which permanently pushes the control key towards its stable angular position) that -this works like a push button.

En outre, les plots 32 de la touche de commande 30 sont engagés sur les chapes 16 du boîtier 10 pour former un moyen de basculement propre de ladite touche de commande 30 autour de l'axe de basculement Y. Ce moyen de basculement propre est indépendant des moyens de basculement 18A de l'entraîneur 15 auquel ladite touche de commande 30 est attachée ce qui permet d'assurer le bon basculement de ladite touche de commande 30 autour de l'axe de basculement Y quelle que soit la zone de la face avant 30A de ladite touche de commande 30 où s'exerce l'appui du doigt de l'utilisateur pour actionner ladite touche.In addition, the pins 32 of the control key 30 are engaged on the yokes 16 of the housing 10 to form a means of specific tilting of said control key 30 around the tilting axis Y. This means of specific tilting is independent tilting means 18A of the driver 15 to which said control key 30 is attached which ensures the correct tilting of said control key 30 around the tilting axis Y whatever the area of the front face 30A of said control key 30 where the user's finger is pressed to activate said key.

Comme le montrent plus particulièrement les figures 1, 2, 17 et 18, l'enjoliveur 40 est un élément de façade rapporté fixement à l'avant du boîtier 10 de l'appareillage de commutation 1. Il se présente sous la forme d'un disque dont le diamètre correspond, au jeu près, au diamètre de l'ouverture circulaire 30E de la touche de commande 30. La face arrière de l'enjoliveur 40 porte quatre pattes 42 munies de dents d'encliquetage aptes à s'encliqueter sur quatre dents d'encliquetage 18B prévues en saillie sur les faces opposées des parois 18 du boîtier 10. Comme le montrent les figures 1 et 5, les dents d'encliquetage 18B sont prévues de part et d'autre des paliers 18A sur les parties des parois 18 qui émergent au-dessus de la face avant 20A du support d'appareillage 20. Une fois encliqueté sur les parois 18 du boîtier 10, l'enjoliveur 40 s'étend à l'intérieur de l'ouverture circulaire 30E de la touche de commande 30 pour fermer cette ouverture circulaire au-dessus du berceau de l'entraîneur 15. Le bord extérieur 41 de l'enjoliveur 40 longe alors le bord intérieur 30C de la touche de commande 30.As shown more particularly by the figures 1 , 2 , 17 and 18 , the hubcap 40 is a facade element fixedly attached to the front of the housing 10 of the switching equipment 1. It is in the form of a disc whose diameter corresponds, within clearance, to the diameter of the circular opening 30E of the control key 30. The rear face of the hubcap 40 carries four tabs 42 provided with latching teeth capable of latching onto four latching teeth 18B provided projecting on the opposite faces of the walls 18 of housing 10. As shown in the figures 1 And 5 , the latching teeth 18B are provided on either side of the bearings 18A on the parts of the walls 18 which emerge above the front face 20A of the equipment support 20. Once snapped onto the walls 18 of the housing 10, the hubcap 40 extends inside the circular opening 30E of the control key 30 to close this circular opening above the cradle of the trainer 15. The outer edge 41 of the hubcap 40 then runs along the inner edge 30C of the control key 30.

De manière remarquable, dans l'appareillage de commutation 1 représenté sur les différentes figures, la partie plane 23 du support d'appareillage 20 comporte deux fentes 24 disposées sous la touche de commande 30, de manière opposée sur un axe de positionnement X perpendiculaire audit axe de basculement Y (voir figure 16) et les deux sources de lumières 112 sont placées sous ladite partie plane 23, au droit desdites fentes 24, pour émettre un flux lumineux au travers des fentes 24 vers l'extérieur dudit appareillage de commutation 1, la position relative des fentes 24 et de la touche de commande 30 est ajustée pour que, dans chacune des deux positions angulaires de la touche de commande 30, celle-ci obture une fente 24 et laisse libre l'autre fente 24 (voir figures 18 et 20).Remarkably, in the switching equipment 1 shown in the different figures, the flat part 23 of the equipment support 20 has two slots 24 arranged under the control key 30, oppositely on a positioning axis X perpendicular to said tilting axis Y (see Figure 16 ) and the two light sources 112 are placed under said flat part 23, to the right of said slots 24, to emit a luminous flux through the slots 24 towards the outside of said switching equipment 1, the relative position of the slots 24 and the control key 30 is adjusted so that, in each of the two angular positions of the control key 30, the latter closes a slot 24 and leaves the other slot 24 free (see figures 18 And 20 ).

A chaque fente 24 il est associé une source de lumière 112.Each slot 24 is associated with a light source 112.

Le flux lumineux émis par l'une des sources de lumière 112 passe au travers de la fente 24 laissée libre par la touche de commande 30 basculée dans une de ses deux positions angulaires et il sort vers l'extérieur de l'appareillage de commutation 1 en traversant l'interstice annulaire A formé entre l'enjoliveur 40 et la plaque de finition 50 tandis que la sortie du flux lumineux émis par l'autre source de lumière 112 est bloquée par la touche de commande 30 qui obture la fente 24 correspondante.The luminous flux emitted by one of the light sources 112 passes through the slot 24 left free by the control key 30 tilted in one of its two angular positions and it exits towards the outside of the switching gear 1 by crossing the annular gap A formed between the hubcap 40 and the finishing plate 50 while the exit of the luminous flux emitted by the other light source 112 is blocked by the control key 30 which closes the corresponding slot 24.

Cet agencement particulièrement avantageux des fentes 24, de la touche de commande 30 et des sources de lumière 112 permet d'éclairer en alternance deux zones distinctes déterminées de la façade de l'appareillage pour indiquer l'endroit précis de la touche de commande 30 où le doigt d'un utilisateur doit appuyer afin de faire basculer la touche de commande 30 pour commander la commutation du mécanisme de l'appareillage de commutation 1. Les zones distinctes éclairées en alternance s'étendent le long de deux parties opposées du bord 51A circulaire intérieur de la plaque de finition 50 qui sont situées sur ledit axe de positionnement X et qui jouxtent les deux parties de la touche de commande 30 qui obturent en alternance lesdites fentes 24.This particularly advantageous arrangement of the slots 24, the control key 30 and the light sources 112 makes it possible to alternately illuminate two specific distinct areas of the front of the equipment to indicate the precise location of the control key 30 where the finger of a user must press in order to switch the control key 30 to control the switching of the mechanism of the switchgear 1. The distinct zones illuminated alternately extend along two opposite parts of the circular edge 51A interior of the finishing plate 50 which are located on said positioning axis X and which adjoin the two parts of the control key 30 which alternately close said slots 24.

Comme le montre plus particulièrement la figure 16, les deux fentes 24 s'étendent de part et d'autre dudit axe de positionnement X suivant deux arcs de cercle appartenant à un cercle C centré sur le point d'intersection O entre ledit axe de basculement Y et ledit axe de positionnement X. Les fentes 24 débouchent sur les faces avant et arrière 23A, 23B de la partie plane 23 du support d'appareillage 20 située au droit de la face arrière 30B de la touche de commande 30 (voir figures 4 et 16).As shown more particularly by Figure 16 , the two slots 24 extend on either side of said positioning axis The slots 24 open onto the front and rear faces 23A, 23B of the flat part 23 of the equipment support 20 located to the right of the rear face 30B of the control key 30 (see figures 4 And 16 ).

Comme le montre la figure 18, préférentiellement, deux parties planes de la face arrière 30B de la touche de commande 30 sont destinées à recouvrir alternativement les débouchés desdites fentes 24 situés sur la face avant 23A de la partie plane 23 tournée vers la touche de commande 30.As shown in the Figure 18 , preferably, two flat parts of the rear face 30B of the control key 30 are intended to alternately cover the outlets of said slots 24 located on the front face 23A of the flat part 23 facing the control key 30.

En variante, comme le montre la figure 20, la touche de commande 30 comprend en saillie de sa face arrière 30B deux nervures 33 distinctes, chaque nervure 33 étant adaptée à s'engager dans la fente 24 obturée par ladite touche de commande 30. Chaque nervure 33 présente alors une forme et une longueur adaptées à la forme et à la longueur de chaque fente 24. Ici, chaque nervure 33 s'étend suivant un arc de cercle tout comme chaque fente 24.Alternatively, as shown in Figure 20 , the control key 30 comprises two distinct ribs 33 projecting from its rear face 30B, each rib 33 being adapted to engage in the slot 24 closed by said control key 30. Each rib 33 then has a shape and a length adapted to the shape and length of each slot 24. Here, each rib 33 extends along an arc of a circle just like each slot 24.

Les deux sources de lumière 112 appartiennent aux deux voyants 100 identiques rapportés sur deux faces externes 11A opposées de la paroi latérale 11 du boîtier 10 au droit desdites fentes 24.The two light sources 112 belong to the two identical indicator lights 100 attached to two opposite external faces 11A of the side wall 11 of the housing 10 to the right of said slots 24.

On a représenté sur les figures 1 et 3 à 11 un mode de réalisation préféré des deux voyants 100 et de leurs moyens de montage sur la paroi latérale 11 du boîtier 10.We represented on the figures 1 And 3 to 11 a preferred embodiment of the two indicator lights 100 and their mounting means on the side wall 11 of the housing 10.

Chaque voyant 100 comporte une carte électronique, un socle 130 et un capot 140 (voir figures 18 et 20).Each indicator 100 includes an electronic card, a base 130 and a cover 140 (see figures 18 And 20 ).

La carte électronique comporte une plaque 110 dont une face supporte un circuit électrique imprimé et un élément lumineux 112 connecté audit circuit imprimé.The electronic card comprises a plate 110, one face of which supports a printed electrical circuit and a light element 112 connected to said printed circuit.

La plaque 110 est réalisée dans un matériau isolant, par exemple en époxy stratifié.The plate 110 is made of an insulating material, for example laminated epoxy.

Ce circuit imprimé se présente par exemple sous la forme d'une fine couche de cuivre gravée par un procédé chimique pour obtenir un ensemble de pistes (non représentées), terminées par des pastilles. Les pistes du circuit imprimé peuvent être recouvertes d'une couche de vernis coloré qui protège les pistes de l'oxydation et d'éventuels courts-circuits. L'élément lumineux 112 est connecté à certaines pastilles des pistes du circuit imprimé. La carte électronique comporte en outre différents composants électriques tels qu'une diode et une résistance connectées à d'autres pastilles du circuit imprimé.This printed circuit is for example in the form of a thin layer of copper etched by a chemical process to obtain a set of tracks (not shown), ending in pads. The printed circuit tracks can be covered with a layer of colored varnish which protects the tracks from oxidation and possible short circuits. The light element 112 is connected to certain pads of the printed circuit tracks. The electronic card also includes different electrical components such as a diode and a resistor connected to other pads of the printed circuit.

L'élément lumineux 112 est par exemple une diode électroluminescente. Il peut s'agir alternativement de tout autre composant électrique lumineux.The light element 112 is for example a light-emitting diode. It may alternatively be any other luminous electrical component.

Le socle 130 et le capot 140 de chaque voyant 100 sont assemblés et forment un boîtier qui enferme hermétiquement la carte électronique. Comme le montrent les figures 6, 10 et 11, pour l'assemblage, le socle 130 comporte sur deux côtés latéraux opposés deux brides 132 et le capot 140 comporte sur deux côtés latéraux opposés deux languettes 141 munies chacune d'une dent 142. Chaque languette 141 du capot 140 est introduite sous une bride 132 du socle 130 pour que la dent 142 de la languette 141 s'accroche sur un bord de la bride 132. La coopération des brides 132 et des languettes 141 est telle que le socle 130 et le capot 140 sont pressés l'un contre l'autre suivant un bord de jonction hermétique.The base 130 and the cover 140 of each indicator 100 are assembled and form a housing which hermetically encloses the electronic card. As shown in the figures 6 , 10 and 11 , for assembly, the base 130 has on two opposite lateral sides two flanges 132 and the cover 140 has on two opposite lateral sides two tongues 141 each provided with a tooth 142. Each tongue 141 of the cover 140 is inserted under a flange 132 of the base 130 so that the tooth 142 of the tongue 141 hooks on an edge of the flange 132. The cooperation of the flanges 132 and the tongues 141 is such that the base 130 and the cover 140 are pressed together against the other following a hermetic joining edge.

Le socle 130 est disposé à l'arrière de la plaque 110 et le capot 140 recouvre le circuit imprimé avec l'élément lumineux 112 et les autres composants électroniques supportés par la face de la plaque 110 de cette carte électronique. Après assemblage du capot 140 et du socle 130, la plaque 110 est prise en sandwich entre la face interne du capot 140 et la face interne 130B du socle 130. Elle est donc maintenue de manière efficace entre ces deux pièces.The base 130 is arranged at the rear of the plate 110 and the cover 140 covers the printed circuit with the light element 112 and the other electronic components supported by the face of the plate 110 of this electronic card. After assembly of the cover 140 and the base 130, the plate 110 is sandwiched between the internal face of the cover 140 and the internal face 130B of the base 130. It is therefore held effectively between these two parts.

Le socle 130 et le capot 140 sont réalisés dans une matière plastique isolante, par exemple par moulage. Ils permettent d'isoler électriquement la carte électronique.The base 130 and the cover 140 are made from an insulating plastic material, for example by molding. They allow the electronic card to be electrically isolated.

Le socle 130 est réalisé dans une matière opaque tandis que le capot 140 est réalisé dans une matière transparente ou translucide par exemple dans un matériau thermoplastique du type polycarbonate transparent.The base 130 is made of an opaque material while the cover 140 is made of a transparent or translucent material, for example a thermoplastic material of the transparent polycarbonate type.

Le capot 140 protège l'élément lumineux 112 et joue également le rôle important d'un diffuseur de lumière pour le flux lumineux émis par l'élément lumineux 112 du voyant 100.The cover 140 protects the light element 112 and also plays the important role of a light diffuser for the luminous flux emitted by the light element 112 of the indicator light 100.

A cet effet, le capot 140 comporte une forme de cône 143 qui se place au droit de l'élément lumineux 112 dont le sommet est dirigé vers ce dernier. Ce cône 143 permet de canaliser le flux lumineux émis par l'élément lumineux 112 suivant une direction principale privilégiée.For this purpose, the cover 140 has a cone shape 143 which is placed to the right of the light element 112, the top of which is directed towards the latter. This cone 143 makes it possible to channel the luminous flux emitted by the luminous element 112 in a preferred main direction.

Comme le montrent les figures 10 et 11, le socle 130 de chaque voyant 100 comporte deux ouvertures 134 pour le passage de deux conducteurs 101, 102 d'alimentation électrique connectés au circuit imprimé de la carte électronique dudit voyant 100. L'un des conducteurs 102 est destiné à être connecté à une des bornes BC de connexion électrique du mécanisme d'appareillage de l'appareillage de commutation 1 et l'autre conducteur 101 est connecté à la carte électronique de l'autre voyant 100.As shown in the figures 10 and 11 , the base 130 of each indicator light 100 has two openings 134 for the passage of two electrical supply conductors 101, 102 connected to the printed circuit of the electronic card of said indicator light 100. One of the conductors 102 is intended to be connected to a terminals BC for electrical connection of the switchgear mechanism of the switchgear 1 and the other conductor 101 is connected to the electronic card of the other indicator 100.

Grâce aux conducteurs 101, 102 les deux voyants 100 sont alimentés en courant en permanence par le mécanisme d'appareillage de l'appareillage de commutation 1 raccordé au réseau électrique. L'élément lumineux 112 de chaque voyant 100 émet donc de façon continue un flux lumineux vers l'extérieur de l'appareillage de commutation 1 et c'est la touche de commande 30 qui bloque la sortie de ce flux lumineux en fonction de sa position angulaire par rapport au support d'appareillage 20 pour qu'une seule zone déterminée de la façade de l'appareillage de commutation 1 reste éclairée.Thanks to the conductors 101, 102, the two indicator lights 100 are permanently supplied with current by the mechanism of the switchgear 1 connected to the electrical network. The light element 112 of each indicator light 100 therefore continuously emits a luminous flux towards the outside of the switching equipment 1 and it is the control key 30 which blocks the exit of this luminous flux as a function of its position. angular relative to the switchgear support 20 so that only one specific area of the facade of the switchgear 1 remains illuminated.

Comme le montrent les figures 6 à 11, le socle 130 de chaque voyant 100 est pourvu d'un moyen d'encliquetage 133 sur un aménagement complémentaire 12B du boîtier 10 de l'appareillage de commutation 1. Le socle 130 de chaque voyant 100 comprend également des moyens de guidage 131A adaptés à coopérer avec des moyens de guidage complémentaires 12A prévus sur le boîtier 10, ces moyens de guidage 131A étant associés audit moyen d'encliquetage 133 pour guider ledit voyant 100 jusqu'à sa position d'encliquetage sur le boîtier 10.As shown in the figures 6 to 11 , the base 130 of each indicator light 100 is provided with a latching means 133 on a complementary arrangement 12B of the housing 10 of the switching equipment 1. The base 130 of each indicator light 100 also includes guide means 131A adapted to cooperate with complementary guide means 12A provided on the housing 10, these guide means 131A being associated with said latching means 133 to guide said indicator light 100 to its latching position on the housing 10.

Plus particulièrement, le socle 130 de chaque voyant 100 présente une face externe 130A (tournée vers l'autre voyant 100) qui porte en saillie une dent 133 d'encliquetage. Comme le montre la figure 9, cette dent 133 comporte en dessous de son nez 133B, une surface d'accrochage 133A qui s'étend à angle droit par rapport à la face externe du socle 130. La face externe 130A du socle 130 porte également en saillie deux pattes rigides 131 parallèles, disposées de part et d'autre de la dent 133. Chaque patte 131 comporte à son extrémité libre un retour dirigé vers l'autre patte 131 si bien que les deux pattes 131 définissent deux rainures 131A tournées l'une vers l'autre (ou autrement dit qui se font face).More particularly, the base 130 of each light 100 has an external face 130A (facing towards the other light 100) which protrudes a latching tooth 133. As shown in the Figure 9 , this tooth 133 has, below its nose 133B, a hooking surface 133A which extends at right angles to the external face of the base 130. The external face 130A of the base 130 also projects two rigid legs 131 parallel, arranged on either side of the tooth 133. Each tab 131 has at its free end a return directed towards the other tab 131 so that the two tabs 131 define two grooves 131A facing one towards the other (or in other words who face each other).

En correspondance, il est prévu sur chacune des faces externes 11A opposées de la paroi latérale 11 du boîtier 10 de l'appareillage de commutation 1, une plate-forme de montage 12 supportée par des montants 14. Chaque plate-forme de montage 12 s'étend à partir de la face arrière 20B du support d'appareillage 20, perpendiculairement à celle-ci. Elle est placée juste en dessous de la partie plane 23 dans laquelle est prévue une des fentes 24 (voir figure 4). Chaque plate-forme de montage 12 présente deux bords latéraux 12A parallèles qui débordent desdits montants 14 (voir figures 7 et 8). Les deux bords latéraux forment des nervures 12A qui s'étendent perpendiculairement à la face arrière 23B de ladite partie plane 23 du support d'appareillage 20. Chaque plate-forme de montage 12 comporte, en outre, dans une face externe 12C, à mi-chemin entre ses deux bords latéraux 12A, une découpe 12B qui s'étend jusqu'au bord de jonction avec la face arrière 23B de la partie plane 23 du support d'appareillage 20 (voir figure 4).Correspondingly, there is provided on each of the opposite external faces 11A of the side wall 11 of the housing 10 of the switchgear 1, a mounting platform 12 supported by uprights 14. Each mounting platform 12 s 'extends from the rear face 20B of the equipment support 20, perpendicular thereto. It is placed just below the flat part 23 in which one of the slots 24 is provided (see Figure 4 ). Each mounting platform 12 has two parallel side edges 12A which extend beyond said uprights 14 (see figures 7 and 8 ). The two lateral edges form ribs 12A which extend perpendicular to the rear face 23B of said flat part 23 of the equipment support 20. Each mounting platform 12 further comprises, in an external face 12C, halfway -path between its two side edges 12A, a cutout 12B which extends to the junction edge with the rear face 23B of the flat part 23 of the equipment support 20 (see figure 4 ).

Comme le montrent les figures 4 et 5, les deux voyants 100 sont approchés du boîtier 10 de l'appareillage de commutation 1 avec la face externe 130A de leur socle 130 tournée vers les plates-formes de montage 12 dudit boîtier 10. Les rainures 131A du socle 130 de chaque voyant 100 sont enfilées sur les nervures 12A de la plate-forme de montage 12 correspondante du boîtier 10 (voir figures 6, 7 et 8) pour guider le voyant 100 jusqu'à ce que la surface d'accrochage 133A de la dent 133 portée par le socle 130 s'accroche sur un bord de la découpe 12B de ladite plate-forme de montage 12 (voir figures 6 et 9). Dans la position accrochée ou encliquetée, la face externe 130A du socle 130 de chaque voyant 100 est plaquée contre la face externe 12C de la plate-forme de montage 12 correspondante et le cône 143 du capot 140 de chaque voyant 100 est placé juste en dessous de la partie plane 23 en étant orienté vers la fente 24 correspondante de cette partie plane 123 du support d'appareillage 20 (voir figures 18 et 20). Le conducteur 101 qui établit la connexion électrique entre les deux voyants 100 est semi-rigide et il est conformé pour épouser la forme externe du boîtier 10 entre les deux voyants 100 accrochés audit boîtier 10. Chaque autre conducteur 102 s'étend librement sur un côté du boîtier 10 (voir figure 5) prêt à être connecté à une borne BC de connexion électrique du mécanisme d'appareillage via une des ouvertures 19A prévues dans la paroi de fond 19 du boîtier 10.As shown in the figures 4 and 5 , the two indicators 100 are approached from the housing 10 of the switching equipment 1 with the external face 130A of their base 130 facing the mounting platforms 12 of said housing 10. The grooves 131A of the base 130 of each indicator 100 are threaded onto the ribs 12A of the mounting platform 12 corresponding to housing 10 (see figures 6, 7 and 8 ) to guide the indicator 100 until the hooking surface 133A of the tooth 133 carried by the base 130 hooks on an edge of the cutout 12B of said mounting platform 12 (see figures 6 and 9 ). In the hooked or clipped position, the external face 130A of the base 130 of each indicator 100 is pressed against the external face 12C of the corresponding mounting platform 12 and the cone 143 of the cover 140 of each indicator 100 is placed just below of the flat part 23 while being oriented towards the corresponding slot 24 of this flat part 123 of the equipment support 20 (see figures 18 And 20 ). The conductor 101 which establishes the electrical connection between the two indicators 100 is semi-rigid and is shaped to match the external shape of the housing 10 between the two indicators 100 attached to said housing 10. Each other conductor 102 extends freely on one side of housing 10 (see Figure 5 ) ready to be connected to an electrical connection terminal BC of the switchgear mechanism via one of the openings 19A provided in the bottom wall 19 of the housing 10.

L'accrochage de chaque voyant 100 à la plate-forme de montage 12 du boîtier 10 est indémontable du fait de l'orientation à angle droit de la surface d'accrochage 133A de chaque dent 133 d'encliquetage portée par le socle 130 du voyant 100.The attachment of each indicator 100 to the mounting platform 12 of the housing 10 cannot be dismantled due to the right angle orientation of the attachment surface 133A of each latching tooth 133 carried by the base 130 of the indicator 100.

Avantageusement, il est prévu sur la face externe du capot 140 de chaque voyant 100 deux flèche F pour indiquer le sens de montage dudit voyant 100 sur le boîtier 10 de l'appareillage de commutation 1.Advantageously, two arrows F are provided on the external face of the cover 140 of each indicator light 100 to indicate the direction of mounting of said indicator light 100 on the housing 10 of the switching equipment 1.

Enfin, on notera que le fond des rainures 131A de guidage prévues sur la face externe 130A du socle 130 de chaque voyant 100 présente une légère inclinaison de façon que la face externe 130A dudit socle 130 dudit voyant 100 ne vienne pas au contact de la face externe 12C de la plate-forme de montage 12 avant que la dent 133 s'accroche sur le bord de la découpe 12B. On évite ainsi tout coincement lors du montage de chaque voyant 100 sur la plate-forme de montage 12 dudit boîtier 10.Finally, it will be noted that the bottom of the guide grooves 131A provided on the external face 130A of the base 130 of each light 100 has a slight inclination so that the external face 130A of said base 130 of said light 100 does not come into contact with the face external 12C of the mounting platform 12 before the tooth 133 hooks on the edge of the cutout 12B. This avoids any jamming when mounting each indicator 100 on the mounting platform 12 of said box 10.

L'invention n'est pas limitée à la description détaillée et diverses autres modifications peuvent y être apportées.The invention is not limited to the detailed description and various other modifications can be made to it.

Selon une variante non représentée, on pourrait prévoir que ladite partie plane appartienne au boîtier qui loge le mécanisme d'appareillage et non pas au support d'appareillage. Dans ce cas, elle ferait partie d'une paroi avant du boîtier qui borde l'ouverture avant dudit boîtier et qui est destinée à fermer au moins partiellement l'ouverture d'un support d'appareillage dans laquelle est rapporté ledit boîtier monté mécaniquement sur ledit support d'appareillage.According to a variant not shown, it could be provided that said flat part belongs to the housing which houses the equipment mechanism and not to the equipment support. In this case, it would be part of a front wall of the housing which borders the front opening of said housing and which is intended to close at least partially the opening of an equipment support in which said housing mounted mechanically on said equipment support.

On pourrait prévoir que la touche de commande ne présente pas la forme d'un anneau entourant l'enjoliveur mais présente une forme plus classique avec une paroi d'appui entourée par l'enjoliveur lui-même entouré par la plaque de finition rapportée sur le support d'appareillage.We could foresee that the control key does not have the shape of a ring surrounding the hubcap but has a more classic shape with a support wall surrounded by the hubcap itself surrounded by the finishing plate attached to the equipment support.

On pourrait également prévoir que le capot de chaque voyant est surmoulé sur le socle de celui-ci.We could also foresee that the cover of each indicator is molded onto its base.

Bien entendu, diverses autres modifications peuvent aussi être apportées à l'invention dans le cadre des revendications annexées.Of course, various other modifications can also be made to the invention within the scope of the appended claims.
