Description

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, un élément compressible 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 du socle et l'entraîneur et contraint contre l'entraîneur, pour obliger l'entraîneur à prendre une seule des deux positions stables, et un élément de retenue venu de matière avec le socle et adapté à maintenir l'élément compressible dans son état inactif vis-à-vis de l'entraîneur.It relates more particularly to an electric switch comprising a base, a driver mounted tilting in the base between two stable positions to bring into contact or out of contact a movable contact element with a fixed contact element, a compressible element adapted to be inactive vis- opposite the trainer, to leave the trainer free to take one or the other of the two stable positions, and to be received between a support surface of the base and the trainer and constrained against the trainer , to force the trainer to take only one of the two stable positions, and a retaining element integrally with the base and adapted to maintain the compressible element in its inactive state vis-à-vis the trainer.

ARRIERE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Un tel commutateur électrique est décrit par exemple dans le document DE 297 22 278 .Such an electrical switch is described for example in the document DE 297 22 278 .

Dans ce document, l'élément de retenue est sécable afin de pouvoir libérer l'élément compressible dans son état actif entre la surface d'appui du socle et l'entraîneur, ce qui permet d'obtenir un fonctionnement en bouton poussoir.In this document, the retaining element is breakable in order to be able to release the compressible element in its active state between the support surface of the base and the driver, which makes it possible to obtain a push button operation.

Toutefois, une fois l'élément de retenue supprimé, il n'est plus possible de replacer l'élément compressible dans son état inactif afin de retrouver un fonctionnement à deux positions stables (parfois dénommé "va-et-vient").However, once the retaining element has been removed, it is no longer possible to return the compressible element to its inactive state in order to find operation in two stable positions (sometimes called " back and forth ").

Afin d'obtenir un fonctionnement réversible, le document DE 297 22 278 propose d'utiliser en variante un élément de retenue amovible par rapport au socle, ce qui implique toutefois l'utilisation d'une pièce supplémentaire et entraîne en outre un risque de perte de l'élément amovible.In order to obtain reversible operation, the document DE 297 22 278 proposes to use a variant of a removable retaining element with respect to the base, which however implies the use of an additional part and also entails a risk of loss of the removable element.

Le documentThe document EP 2 978 006EP 2,978,006 décrit également un commutateur électrique.also describes an electrical switch.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Dans ce contexte, la présente invention propose un commutateur électrique tel que défini en introduction, caractérisé en ce que l'élément de retenue est déplaçable de manière réversible entre une position de retenue où il maintient l'élément compressible dans son état inactif vis-à-vis de l'entraîneur et une position écartée où il laisse libre l'extension de l'élément compressible jusqu'à l'entraîneur.In this context, the present invention provides an electrical switch as defined in the introduction, characterized in that the retaining element is reversibly movable between a retaining position where it keeps the compressible element in its inactive state vis-à-vis -vis the trainer and an open position where it leaves free the extension of the compressible element to the trainer.

Ainsi, en déplaçant l'élément de retenue entre sa position de retenue et sa position écartée, l'utilisateur peut choisir, de manière réversible, de mettre l'élément compressible dans son état actif (en appui entre le socle et l'entraîneur) ou dans son état inactif, et donc de configurer le commutateur électrique en mode bouton poussoir ou en mode va-et-vient.Thus, by moving the retaining element between its retaining position and its separated position, the user can choose, reversibly, to put the compressible element in its active state (resting between the base and the trainer) or in its inactive state, and therefore configure the electrical switch in push button mode or in back-and-forth mode.

L'élément de retenue est par ailleurs venu de matière avec le socle ce qui simplifie la production du commutateur électrique et évite la perte de cet élément.The retaining element also came integrally with the base, which simplifies the production of the electrical switch and prevents the loss of this element.

D'autres caractéristiques non limitatives et avantageuses du commutateur électrique conforme à l'invention sont les suivantes :

  • l'élément compressible comprend un ressort ;
  • l'élément compressible comprend un capuchon ;
  • le ressort est monté comprimé entre le socle et la tête du capuchon (par exemple entre le fond d'un puits de réception du ressort et la tête du capuchon) ;
  • le socle comprend une bordure périphérique formant support d'appareillage, telle qu'une bordure périphérique munie d'ouvertures traversantes pour permettre le passage de vis de fixation du commutateur électrique dans un boîtier ;
  • l'élément de retenue comprend un bras pourvu d'un ergot adapté à maintenir l'élément compressible dans son état inactif ;
  • le socle comprend un muret périphérique, par exemple un muret périphérique s'étendant vers l'avant à partir d'un corps du socle ou un muret périphérique s'étendant vers l'avant à partir d'une partie de liaison entre le corps du socle et la bordure périphérique ;
  • le bras s'étend au droit d'une fenêtre formée dans le muret périphérique ;
  • le bras s'étend à partir d'un premier bord de la fenêtre ;
  • une extrémité libre du bras est en appui contre un second bord de la fenêtre opposé au premier bord de la fenêtre lorsque l'élément de retenue est dans la position écartée ;
  • le premier bord est un bord arrière de la fenêtre de sorte que l'extrémité libre du bras est accessible au niveau d'une région avant du socle (par exemple au niveau d'un bord périphérique avant du muret périphérique et, ici, à l'avant de la bordure périphérique) ;
  • le premier bord est un bord avant de la fenêtre de sorte que l'extrémité libre du bras est accessible par l'arrière du socle (c'est-à-dire ici à l'arrière de la bordure périphérique).

On a représenté sur les figures 1 à 13 deux modes de réalisation envisageables d'un commutateur électrique 100 ; 200 conforme à l'invention.We have represented on Figures 1 to 13 two embodiments conceivable of an electrical switch 100; 200 according to the invention.

Ce commutateur électrique 100 ; 200 est destiné à être logé 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 ou dans la paroi murale.This electrical switch 100; 200 is intended to be housed in a box (not shown) intended to be attached to or in a wall, according to a surface mounting or by embedding of this box on or in the wall.

Le commutateur électrique 100 ; 200 est alors raccordé au réseau électrique pour son alimentation.The electric switch 100; 200 is then connected to the electrical network for its 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 ; 200. 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 with respect to the direction of the gaze of the user towards the wall on which this electrical switch 100 is attached; 200. Thus, when the switch is installed in a room, the front will designate the side facing the inside of the room and the rear will designate the side facing away from the room.

Le commutateur électrique 100 ; 200 comporte un mécanisme de commutation 120 ; 220 logé dans un socle 110 ; 210 isolant.The electric switch 100; 200 includes a switching mechanism 120; 220 housed in a base 110; 210 insulation.

Le socle 110 ; 210 est porté par un support d'appareillage qui permet le montage de l'appareillage électrique (ici un commutateur électrique) dans le boîtier susmentionné (rapporté quant à lui sur ou dans la paroi murale).The base 110; 210 is carried by an apparatus support which allows the mounting of the electrical apparatus (here an electrical switch) in the aforementioned case (attached to it on or in the wall).

Dans certains modes de réalisation, le support d'appareillage est une pièce distincte du socle. Le support d'appareillage et le socle comprennent dans ce cas des moyens d'assemblage réciproques.In certain embodiments, the apparatus support is a separate part from the base. The apparatus support and the base in this case comprise reciprocal assembly means.

Dans l'exemple décrit ici, le support d'appareillage est réalisé sous la forme d'une bordure périphérique 116 ; 216 venue de matière avec le socle 110 ; 210 et qui s'étend sur toute la périphérie du socle 110 ; 210.In the example described here, the apparatus support is produced in the form of a peripheral edge 116; 216 integral with the base 110; 210 and which extends over the entire periphery of the base 110; 210.

Le socle 110 ; 210 comporte un corps 112 ; 212 et, sur toute la périphérie du corps 112 ; 212, une partie (plane) de liaison 113 ; 213 entre le corps 112 ; 212 et la bordure périphérique 116 ; 216 formant support d'appareillage.The base 110; 210 has a body 112; 212 and, over the entire periphery of the body 112; 212, a (flat) connecting part 113; 213 between the body 112; 212 and the peripheral border 116; 216 forming apparatus support.

Le socle 110 ; 210 comporte également un muret périphérique 114 ; 214 (ici fermé), perpendiculaire à la partie de liaison 113 ; 213 et s'étendant notamment vers l'avant à partir de la partie de liaison 113 ; 213.The base 110; 210 also includes a peripheral wall 114; 214 (here closed), perpendicular to the connecting part 113; 213 and extending in particular forward from the connecting portion 113; 213.

Le corps 112 ; 212 est ouvert à l'avant (dans l'espace délimité par le muret périphérique 114 ; 214) et définit des logements adaptés à recevoir des éléments (notamment des bornes de connexion électrique 130, 132, 134 visibles en figure 1) du mécanisme de commutation 120 ; 220.The body 112; 212 is open at the front (in the space delimited by the peripheral wall 114; 214) and defines housings adapted to receive elements (in particular electrical connection terminals 130, 132, 134 visible at figure 1 ) the switching mechanism 120; 220.

La bordure périphérique 116 ; 216 comporte une pluralité d'ouvertures traversantes 118 ; 218, ici en forme de trou de serrure, destinées à recevoir chacune une vis de montage du commutateur électrique 100 ; 200 dans un boîtier pour fixation sur ou dans une paroi murale, comme déjà mentionné.The peripheral border 116; 216 has a plurality of through openings 118; 218, here in the form of a keyhole, each intended to receive a mounting screw for the electrical switch 100; 200 in a box for fixing on or in a wall, as already mentioned.

Le mécanisme de commutation 120 ; 220 reçu dans le socle 110 ; 210 comporte notamment un capot 122 ; 222, un balai 124, un entraîneur 126 ; 226 et des moyens élastiques de basculement 129.The switching mechanism 120; 220 received in the base 110; 210 includes in particular a cover 122; 222, a brush 124, a coach 126; 226 and elastic tilting means 129.

Le capot 122 ; 222 est une pièce isolante qui retient des pièces électriques conductrices logées dans le socle 110 ; 210, notamment les bornes de connexion électrique 130, 132, 134 à raccorder au réseau électrique local.The cover 122; 222 is an insulating part which retains conductive electrical parts housed in the base 110; 210, in particular the electrical connection terminals 130, 132, 134 to be connected to the local electrical network.

Ces bornes de connexion électrique 130, 132, 134 sont par exemple des bornes à connexion automatique, de sorte que chacune d'entre elles est manœuvrable par un levier de déconnexion qui traverse une ouverture pratiquée dans la paroi du socle 110 ; 210 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 ; 225, portée par le capot 122 ; 222 et accessible à l'usager à l'extérieur du socle 110 ; 210.These electrical connection terminals 130, 132, 134 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 wall of the base 110; 210 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 disconnection lever comprises a control lever 125; 225, carried by the cover 122; 222 and accessible to the user outside the base 110; 210.

Comme visible en figure 1, le capot 122 comporte par exemple des pattes d'encliquetage élastiques 123 destinées à coopérer avec des évidements 1100 formés dans le corps 112 du socle 110 pour son montage par encliquetage dans le socle 110.As visible in figure 1 , the cover 122 comprises for example elastic snap-on lugs 123 intended to cooperate with recesses 1100 formed in the body 112 of the base 110 for its snap-on mounting in the base 110.

Le balai 124 mentionné plus haut est 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 124, avec au moins un élément de contact fixe, par exemple un grain de contact fixe 131 porté par une lame de contact raccordée électriquement à l'une des bornes de connexion électrique 130.The brush 124 mentioned above is suitable for tilting around a tilting axis between two extreme positions, to bring into contact or out of contact a movable contact element, for example a movable contact grain carried by the brush 124, with at at least one fixed contact element, for example a fixed contact grain 131 carried by a contact blade electrically connected to one of the electrical connection terminals 130.

L'entraîneur 126 ; 226 est monté basculant sur le socle 110 ; 210, par exemple au moyen de deux pions formés sur l'entraîneur 126 ; 226 et respectivement engagés dans deux paliers correspondants formés dans le socle 110 ; 210 de manière à définir un axe de basculement pour l'entraîneur 126 ; 226.Coach 126; 226 is pivotally mounted on the base 110; 210, for example by means of two pawns formed on the coach 126; 226 and respectively engaged in two corresponding bearings formed in the base 110; 210 so as to define a tilting axis for the driver 126; 226.

L'entraîneur 126 ; 226 est une pièce isolante, réalisée par exemple en matière plastique par moulage.Coach 126; 226 is an insulating part, made for example of plastic by molding.

L'entraîneur 126 ; 226 s'étend (dans l'espace délimité par le muret périphérique 114 ; 214) de part et d'autre de son axe de basculement et se prolonge à une de ses extrémités par un doigt 127 ; 227 dont la fonction est présentée plus bas.Coach 126; 226 extends (in the space delimited by the peripheral wall 114; 214) on either side of its pivot axis and is extended at one of its ends by a finger 127; 227 whose function is presented below.

Un élément tubulaire 128 ; 228 solidaire de l'entraîneur 126 ; 226 (ici venu de matière avec l'entraîneur 126 ; 226) s'étend vers l'arrière à partir de l'entraîneur 126 ; 226, au niveau de l'axe de basculement et à travers une ouverture ménagée à cet effet dans le capot 122 ; 222.A tubular element 128; 228 secured to coach 126; 226 (here integral with the driver 126; 226) extends rearward from the driver 126; 226, at the level of the tilting axis and through an opening provided for this purpose in the cover 122; 222.

Comme bien visible sur les figures 4, 6 et 10 à 13, le capot 122 ; 222 est d'ailleurs monté dans l'espace formé dans le socle 110 ; 210 et délimité par le muret périphérique 114 ; 214, entre le corps 112 ; 212 du socle 110 ; 210 et l'entraîneur 126 ; 226.As clearly visible on figures 4, 6 and 10 to 13 , the cover 122; 222 is also mounted in the space formed in the base 110; 210 and delimited by the peripheral wall 114; 214, between the body 112; 212 of base 110; 210 and the coach 126; 226.

Les moyens élastiques de basculement 129 déjà mentionnés (ici un ressort monté dans l'élément tubulaire 128) sont aptes, après franchissement d'un point dur, à solliciter le balai 124 en direction de l'une ou de l'autre de ses positions extrêmes en fonction de la position de l'entraîneur 126 ; 226.The elastic tilting means 129 already mentioned (here a spring mounted in the tubular element 128) are able, after crossing a hard point, to urge the brush 124 towards one or other of its positions extremes depending on the position of the coach 126; 226.

Ainsi, en manœuvrant une touche 140 (représentée seulement en figure 1) solidaire de l'entraîneur 126 ; 226 (généralement montée sur l'entraîneur 126 ; 226 par encliquetage), l'utilisateur commande le basculement des moyens élastiques de basculement 129, et donc du balai 124, de sorte à mettre en contact ou hors contact l'élément de contact mobile avec l'élément de contact fixe 131.Thus, by operating a key 140 (shown only in figure 1 ) in solidarity with coach 126; 226 (generally mounted on the driver 126; 226 by snap-fastening), the user controls the tilting of the elastic tilting means 129, and therefore of the brush 124, so as to bring the movable contact element into contact or out of contact with the fixed contact element 131.

Le corps 112; 212 du socle 110; 210 forme (dans une région périphérique voisine du muret périphérique 114 ; 214) un puits 115 ; 215 de réception d'un élément compressible 150 ; 250.The body 112; 212 of base 110; 210 forms (in a peripheral region adjacent to the peripheral wall 114; 214) a well 115; 215 for receiving a compressible element 150; 250.

L'élément compressible 150 ; 250 comprend ici un ressort 152 ; 252 et un capuchon 154 ; 254 monté à coulissement relativement au puits 115 ; 215 selon l'axe de compression du ressort 152 ; 252.The compressible element 150; 250 here comprises a spring 152; 252 and a cap 154; 254 slidably mounted relative to well 115; 215 along the compression axis of the spring 152; 252.

Le capuchon 154 ; 254 (ici de forme cylindrique) est creux de manière à loger le ressort 152 ; 252 de sorte que le ressort 152 ; 252 est reçu (en compression) entre le fonds du puits 115 ; 225 et une tête 155 ; 255 du capuchon 154 ; 254.The cap 154; 254 (here cylindrical in shape) is hollow so as to accommodate the spring 152; 252 so that the spring 152; 252 is received (in compression) between the bottom of well 115; 225 and a head 155; 255 of the cap 154; 254.

Le capuchon 154 ; 254 présente par ailleurs une excroissance 156 ; 256 (située au moins dans une région dirigée vers le muret périphérique 114 ; 214) utilisée pour retenir l'élément compressible 150 ; 250 en position comprimée, inactive vis-à-vis de l'entraîneur 126 ; 226 comme expliqué plus loin.The cap 154; 254 also has a projection 156; 256 (located at least in a region directed towards the peripheral wall 114; 214) used to retain the compressible element 150; 250 in the compressed position, inactive vis-à-vis the coach 126; 226 as explained below.

Dans le mode de réalisation des figures 1 à 7, le capuchon 154 est reçu dans le puits de réception 115 (le puits de réception 115 ayant une forme complémentaire de celle du capuchon 154, ici une forme cylindrique) ; l'excroissance 156 est par ailleurs formée dans le prolongement de la tête 155, la face avant de l'excroissance 156 étant d'ailleurs ici située dans le plan de la face avant de la tête 155.In the embodiment of Figures 1 to 7 , the cap 154 is received in the reception well 115 (the reception well 115 having a shape complementary to that of the cap 154, here a cylindrical shape); the protrusion 156 is also formed in the extension of the head 155, the front face of the protrusion 156 also being here located in the plane of the front face of the head 155.

Dans le mode de réalisation des figures 8 à 13, le capuchon 254 est reçu dans un évidement annulaire 257 entourant pour partie au moins le puits 215. L'excroissance 256 est quant à elle formée par une collerette s'étendant sur une partie au moins de la circonférence du capuchon cylindrique 254, ici dans une région voisine de la tête 255 (selon l'axe de compression du ressort 252).In the embodiment of figures 8 to 13 , the cap 254 is received in an annular recess 257 partially surrounding at least the well 215. The protrusion 256 is itself formed by a flange extending over at least part of the circumference of the cylindrical cap 254, here in a region close to the head 255 (along the compression axis of the spring 252).

Le muret périphérique 114 ; 214 du socle 110 ; 210 présente une fenêtre 111 ; 211 au droit de laquelle s'étend un bras 117 ; 217 venu de matière avec le socle 110 ; 210 et lié au socle 110 ; 210 seulement au niveau d'un bord de la fenêtre 111 ; 211.The peripheral wall 114; 214 of base 110; 210 has a window 111; 211 to the right of which extends an arm 117; 217 integrally with the base 110; 210 and linked to the base 110; 210 only at an edge of window 111; 211.

Comme bien visible sur les figures 3 et 9, le bras 117 ; 217 présente un ergot 119 ; 219 faisant face à l'élément compressible 150 ; 250 et adapté à coopérer avec l'excroissance 156 ; 256 du capuchon 154 ; 254 (dans une position particulière du bras 117 ; 217 comme expliqué plus loin) de manière à retenir l'élément compressible 150 ; 250 dans sa position comprimée inactive par rapport à l'entraîneur 126 ; 226 : le bras 117 ; 217 muni de l'ergot 119 ; 219 forme ainsi un élément de retenue de l'élément compressible 150 ; 250 dans sa position inactive vis-à-vis de l'entraîneur 126 ; 226.As clearly visible on figures 3 and 9 , arm 117; 217 has a lug 119; 219 facing the compressible element 150; 250 and adapted to cooperate with the projection 156; 256 of the cap 154; 254 (in a particular position of the arm 117; 217 as explained below) so as to retain the compressible element 150; 250 in its inactive compressed position relative to the driver 126; 226: arm 117; 217 with lug 119; 219 thus forms a retaining element for the compressible element 150; 250 in its inactive position with respect to the coach 126; 226.

Le bras 117 ; 217 est (pour partie au moins) déplaçable par rapport au reste du socle 110 ; 210 (en particulier par rapport au puits 115 ; 215 de réception de l'élément compressible 150 ; 250) de sorte que l'ergot 119 ; 219 peut être éloigné de l'excroissance 156 ; 256 afin de libérer l'élément compressible 150 ; 250, lequel peut alors s'étendre jusqu'à ce que la tête 155 ; 255 du capuchon 154 ; 254 vienne au contact du doigt 127 ; 227 de l'entraîneur 126 ; 226.Arm 117; 217 is (at least partly) movable relative to the rest of the base 110; 210 (in particular with respect to the well 115; 215 for receiving the compressible element 150; 250) so that the lug 119; 219 can be moved away from the outgrowth 156; 256 to release the compressible element 150; 250, which can then extend until the head 155; 255 of the cap 154; 254 comes into contact with finger 127; 227 of coach 126; 226.

Les caractéristiques de raideur de l'élément compressible 150 ; 250 (ici précisément du ressort 152 ; 252) sont telles que l'élément compressible 150 ; 250 (ici la tête 155 ; 255) exerce alors une force suffisante sur l'entraîneur 126 ; 226 pour le maintenir dans une seule des deux positions stables du mécanisme de commutation 120 ; 220, sauf lorsqu'un utilisateur exerce sur l'entraîneur 126 ; 226 un effort opposé à celui généré par l'élément compressible 150 ; 250 : le commutateur électrique 100 ; 200 fonctionne alors en bouton poussoir.The stiffness characteristics of the compressible element 150; 250 (here precisely spring 152; 252) are such that the compressible element 150; 250 (here the head 155; 255) then exerts a sufficient force on the driver 126; 226 to keep it in only one of the two stable positions of the switching 120; 220, except when a user exercises on the coach 126; 226 a force opposite to that generated by the compressible element 150; 250: the electrical switch 100; 200 then operates as a push button.

Dans l'exemple décrit ici, le bras 117 ; 217 est pour partie déplaçable du fait de sa forme (allongée) et de son épaisseur (faible) qui lui procurent une certaine flexibilité permettant un déplacement de l'ergot 119 ; 219 par rapport au bord de la fenêtre 111 ; 211 portant le bras 117 ; 217. En variante ou en complément, on pourrait prévoir de relier le bras 117 ; 217 au bord concerné de la fenêtre 111 ; 211 par une partie d'épaisseur réduite, ce qui permet également le déplacement de la partie du bras 117 ; 217 portant l'ergot 119 ; 219 par rapport bord de la fenêtre 111 ; 211 (et par rapport au reste du socle 110 ; 210).In the example described here, the arm 117; 217 is partly movable because of its shape (elongated) and its thickness (small) which give it a certain flexibility allowing a displacement of the lug 119; 219 relative to the edge of window 111; 211 carrying arm 117; 217. As a variant or in addition, provision could be made to connect the arm 117; 217 at the relevant edge of window 111; 211 by a part of reduced thickness, which also allows the movement of the part of the arm 117; 217 bearing lug 119; 219 relative to the edge of window 111; 211 (and compared to the rest of the base 110; 210).

On remarque par ailleurs, comme visible sur les figures 4, 10 et 13, que le bras 117 ; 217 est agencé (notamment du fait de son orientation) de manière à définir une position stable lorsque l'excroissance 156 ; 256 du capuchon 154 ; 254 vient en butée contre l'ergot 119 ; 219 porté par le bras 117 ; 217.We also note, as visible on the figures 4 , 10 and 13 , that the arm 117; 217 is arranged (in particular because of its orientation) so as to define a stable position when the projection 156; 256 of the cap 154; 254 abuts against lug 119; 219 carried by the arm 117; 217.

Lorsque l'élément de retenue (ici le bras 117 ; 217) est déplacé à l'écart de l'élément compressible 150 ; 250 (en pratique par l'utilisateur comme expliqué en détail plus loin), l'élément de retenue (ici le bras 117 ; 217) atteint une autre position stable de manière à ne pas venir interférer (involontairement) avec l'élément compressible 150 ; 250.When the retaining element (here the arm 117; 217) is moved away from the compressible element 150; 250 (in practice by the user as explained in detail below), the retaining element (here the arm 117; 217) reaches another stable position so as not to interfere (unintentionally) with the compressible element 150 ; 250.

On prévoit ici pour ce faire que, lors du déplacement du bras 117 ; 217 de sa position de retenue de l'élément compressible 150 ; 250 à sa position écartée de l'élément compressible 150 ; 250, une partie (ici l'extrémité libre) du bras 117 ; 217 vienne au contact, puis dépasse une partie correspondante du socle 110 ; 210 (ici un bord de la fenêtre 111 ; 211, précisément le bord de la fenêtre 111 ; 211 opposé à celui portant le bras 117 ; 217), par exemple du fait de l'élasticité de l'une et/ou l'autre desdites parties.It is here provided to do this that, when the arm 117 is displaced; 217 from its position for retaining the compressible element 150; 250 at its position separated from the compressible element 150; 250, a part (here the free end) of the arm 117; 217 comes into contact, then exceeds a corresponding part of the base 110; 210 (here an edge of the window 111; 211, precisely the edge of the window 111; 211 opposite to that carrying the arm 117; 217), for example due to the elasticity of one and / or the other of said parties.

Comme visible sur les figures 3 et 9, au moins une de ces parties (à savoir ici l'extrémité libre du bras 117 ; 217 et le bord de la fenêtre 111 ; 211) peut d'ailleurs présenter une extrémité libre d'épaisseur réduite afin de faciliter le passage de la partie portée par le bras 117 ; 217 au-delà de la partie portée par le reste du socle 110 ; 210.As seen on figures 3 and 9 , at least one of these parts (namely here the free end of the arm 117; 217 and the edge of the window 111; 211) may moreover have a free end of reduced thickness in order to facilitate the passage of the part carried by the arm 117; 217 beyond the part carried by the rest of the base 110; 210.

Dans l'exemple décrit ici, lorsque l'extrémité libre du bras 117 ; 217 dépasse le bord de la fenêtre 111 ; 211, cette extrémité libre reste en appui sur ce bord de la fenêtre 111 ; 211, du côté opposé à l'élément compressible 150 ; 250, de sorte que le bras 117 ; 217 s'étend à travers la fenêtre 111 ; 211, comme bien visible sur les figures 6 et 11.In the example described here, when the free end of the arm 117; 217 extends beyond the edge of window 111; 211, this free end remains supported on this window edge 111; 211, on the side opposite to the compressible element 150; 250, so that the arm 117; 217 extends through window 111; 211, as clearly visible on figures 6 and 11 .

Dans le mode de réalisation des figures 1 à 7, le bras 117 est lié au reste du socle au niveau du bord arrière de la fenêtre 111 de sorte que l'extrémité libre du bras 117 est situé à proximité du bord avant de la fenêtre 111 (lorsque le bras 117 est dans sa position de retenue de l'élément compressible 150), ou en appui sur le bord avant de la fenêtre 111 (lorsque le bras 117 est dans sa position écartée de l'élément compressible 150).In the embodiment of Figures 1 to 7 , the arm 117 is linked to the rest of the base at the rear edge of the window 111 so that the free end of the arm 117 is located near the front edge of the window 111 (when the arm 117 is in its position retaining the compressible element 150), or pressing on the front edge of the window 111 (when the arm 117 is in its position away from the compressible element 150).

Ainsi, dans ce mode de réalisation, le bras 117 est manœuvrable de l'avant du socle 110, comme bien visible sur les figures 5 et 7 et expliqué à présent.Thus, in this embodiment, the arm 117 can be maneuvered from the front of the base 110, as clearly visible on the Figures 5 and 7 and explained now.

La figure 4 présente la situation dans laquelle l'élément de retenue (ici le bras 117 pourvu de l'ergot 119) est dans sa position de retenue de l'élément compressible 150 dans sa position comprimée inactive vis-à-vis de l'entraîneur 126.The figure 4 presents the situation in which the retaining element (here the arm 117 provided with the lug 119) is in its position for retaining the compressible element 150 in its compressed position inactive vis-à-vis the driver 126.

L'entraîneur 126 peut alors prendre l'une ou l'autre de ses deux positions stables sous l'action de l'utilisateur (par l'intermédiaire de la touche 140) : le commutateur électrique 100 fonctionne en mode va-et-vient.The coach 126 can then take one or the other of its two stable positions under the action of the user (by means of the key 140): the electric switch 100 operates in back-and-forth mode .

S'il souhaite plutôt un fonctionnement en mode bouton poussoir, l'utilisateur déplace l'extrémité libre du bras 117 (typiquement avec un outil, ici un tournevis plat 300 comme représenté en figure 5) vers la fenêtre 111 jusqu'à ce que cette extrémité libre dépasse le bord avant de la fenêtre 111 et reste retenue en appui sur ce bord avant, comme représenté en figure 6.If he rather wishes to operate in push button mode, the user moves the free end of the arm 117 (typically with a tool, here a flat screwdriver 300 as shown in figure 5 ) towards the window 111 until this free end exceeds the front edge of the window 111 and remains retained in abutment on this front edge, as shown in figure 6 .

L'élément de retenue formé par le bras 117 muni de l'ergot 119 n'interagit alors plus avec l'élément compressible 150, de sorte que l'élément compressible 150 est libéré et peut s'étendre : la tête 155 de l'élément compressible 150 entre en contact avec le doigt 127 formé sur l'entraîneur 126, puis l'élément compressible 150 fait éventuellement basculer l'entraîneur 126 dans une des deux positions stables (si l'entraîneur 126 occupait alors son autre position stable) et contraint en tout cas l'entraîneur 126 dans cette position stable, comme représenté en figure 6 : le commutateur électrique 100 fonctionne ainsi en bouton poussoir (seul un effort exercé sur la touche 140 par l'utilisateur pouvant alors amener l'entraîneur dans son autre position, et ce seulement pendant la durée de cet effort).The retaining element formed by the arm 117 provided with the lug 119 then no longer interacts with the compressible element 150, so that the compressible element 150 is released and can extend: the head 155 of the compressible element 150 comes into contact with the finger 127 formed on the driver 126, then the compressible element 150 possibly causes the coach 126 to tilt into one of the two stable positions (if the coach 126 then occupied its other stable position) and constrained in any case the coach 126 in this stable position, as shown in figure 6 : the electric switch 100 thus functions as a push button (only a force exerted on the key 140 by the user can then bring the coach to its other position, and this only during the duration of this effort).

S'il souhaite revenir à un fonctionnement en mode va-et-vient, l'utilisateur exerce un effort (typiquement au moyen d'un outil, ici encore au moyen d'un tournevis plat 300 comme représenté en figure 7) sur l'extrémité libre du bras 117 de manière à ce que cette extrémité libre dépasse le bord avant de la fenêtre 111 (par élasticité de ce bord avant et/ou de l'extrémité libre du bras 117 et/ou du bras 117 lui-même) et traverse la fenêtre 111 en direction de l'élément compressible 150 ; simultanément, l'utilisateur fait basculer l'entraîneur 126 dans sa position où le doigt 127 formé sur l'entraîneur 126 comprime l'élément compressible 150.If he wishes to return to operation in reciprocating mode, the user exerts a force (typically by means of a tool, here again by means of a flat screwdriver 300 as shown in figure 7 ) on the free end of the arm 117 so that this free end exceeds the front edge of the window 111 (by elasticity of this front edge and / or of the free end of the arm 117 and / or of the arm 117 itself -same) and crosses the window 111 in the direction of the compressible element 150; simultaneously, the user switches the driver 126 into its position where the finger 127 formed on the driver 126 compresses the compressible element 150.

Ces deux actions (ici simultanées) permettent au commutateur électrique 100 de retrouver sa configuration illustrée en figure 4 (l'excroissance 156 de l'élément compressible 150 venant se loger derrière l'ergot 119 de l'élément de retenue) et donc son fonctionnement en mode va-et-vient.These two actions (here simultaneous) allow the electrical switch 100 to return to its configuration illustrated in figure 4 (the protrusion 156 of the compressible element 150 being housed behind the lug 119 of the retaining element) and therefore its operation in back-and-forth mode.

Dans le mode de réalisation des figures 8 à 13, le bras 217 est lié au reste du socle au niveau du bord avant de la fenêtre 211 de sorte que l'extrémité libre du bras 217 est situé à proximité du bord arrière de la fenêtre 211 (lorsque le bras 217 est dans sa position de retenue de l'élément compressible 250, comme bien visible en figure 9), ou en appui sur le bord arrière de la fenêtre 211 (lorsque le bras 217 est dans sa position écartée de l'élément compressible 250 visible en figure 11).In the embodiment of figures 8 to 13 , the arm 217 is linked to the rest of the base at the front edge of the window 211 so that the free end of the arm 217 is located near the rear edge of the window 211 (when the arm 217 is in its position retaining compressible element 250, as clearly visible in figure 9 ), or resting on the rear edge of the window 211 (when the arm 217 is in its position away from the compressible element 250 visible at figure 11 ).

Ainsi, dans cet autre mode de réalisation, le bras 217 est manœuvrable par l'arrière du socle 210, comme montré en figure 12 et expliqué à présent.Thus, in this other embodiment, the arm 217 can be operated from the rear of the base 210, as shown in figure 12 and explained now.

La figure 10 présente la situation dans laquelle l'élément de retenue (ici le bras 217 pourvu de l'ergot 219) est dans sa position de retenue de l'élément compressible 250 dans sa position comprimée inactive vis-à-vis de l'entraîneur 226.The figure 10 presents the situation in which the retaining element (here the arm 217 provided with the lug 219) is in its position for retaining the compressible element 250 in its compressed position inactive vis-à-vis the driver 226.

L'entraîneur 226 peut alors prendre l'une ou l'autre de ses deux positions stables sous l'action de l'utilisateur : le commutateur électrique 200 fonctionne en mode va-et-vient.The driver 226 can then take one or the other of its two stable positions under the action of the user: the electric switch 200 operates in back-and-forth mode.

S'il souhaite plutôt un fonctionnement en mode bouton poussoir, l'utilisateur déplace l'extrémité libre du bras 217 (typiquement avec un outil tel qu'un tournevis plat, en agissant de l'arrière du socle 210) vers la fenêtre 211 jusqu'à ce que cette extrémité libre dépasse le bord arrière de la fenêtre 211 et reste retenu en appui sur ce bord arrière, comme représenté en figure 11.If he rather wishes to operate in push button mode, the user moves the free end of the arm 217 (typically with a tool such as a flat screwdriver, acting from the rear of the base 210) towards the window 211 until 'in that this free end exceeds the rear edge of the window 211 and remains retained in abutment on this rear edge, as shown in figure 11 .

L'élément de retenue formé par le bras 217 muni de l'ergot 219 n'interagit alors plus avec l'élément compressible 250, de sorte que l'élément compressible 250 est libéré et peut s'étendre : la tête 255 de l'élément compressible 250 entre en contact avec le doigt 227 formé sur l'entraîneur 226, puis l'élément compressible 250 fait éventuellement basculer l'entraîneur 226 dans une des deux positions stables (si l'entraîneur 226 occupait alors son autre position stable) et contraint en tout cas l'entraîneur 226 dans cette position stable, comme représenté en figure 11 : le commutateur électrique 200 fonctionne ainsi en bouton poussoir (seul un effort exercé par l'utilisateur pouvant alors amener l'entraîneur 226 dans son autre position, et ce seulement pendant la durée de cet effort).The retaining element formed by the arm 217 provided with the lug 219 then no longer interacts with the compressible element 250, so that the compressible element 250 is released and can extend: the head 255 of the compressible element 250 comes into contact with the finger 227 formed on the trainer 226, then the compressible element 250 eventually causes the trainer 226 to tip into one of the two stable positions (if the trainer 226 then occupied its other stable position) and constrained in any case the trainer 226 in this stable position, as shown in figure 11 : The electric switch 200 thus operates as a push button (only a force exerted by the user which can then bring the coach 226 into its other position, and this only during the duration of this effort).

S'il souhaite revenir à un fonctionnement en mode va-et-vient, l'utilisateur exerce un effort (typiquement au moyen d'un outil, ici au moyen d'un tournevis plat 400 comme représenté en figure 12) sur l'extrémité libre du bras 217 de manière à ce que cette extrémité libre dépasse le bord arrière de la fenêtre 211 (par élasticité de ce bord avant et/ou de l'extrémité libre du bras 217 et/ou du bras 217 lui-même) et traverse la fenêtre 211 en direction de l'élément compressible 250, comme représenté en figure 12.If he wishes to return to operation in back-and-forth mode, the user exerts a force (typically by means of a tool, here by means of a flat screwdriver 400 as shown in figure 12 ) on the free end of the arm 217 so that this free end exceeds the rear edge of the window 211 (by elasticity of this front edge and / or of the free end of the arm 217 and / or of the arm 217 itself -same) and crosses the window 211 in the direction of the compressible element 250, as shown in figure 12 .

L'utilisateur fait par ailleurs basculer l'entraîneur 226 dans sa position où le doigt 227 formé sur l'entraîneur 226 comprime l'élément compressible 250 jusqu'à ce que la collerette 256 de l'élément compressible 250 passe derrière l'ergot 219 formé sur le bras 217 et que l'élément de retenue formé par le bras 217 muni de l'ergot 219 retienne ainsi l'élément compressible 250 dans sa position inactive vis-à-vis de l'entraîneur 226 : le commutateur électrique 200 retrouve sa configuration permettant un fonctionnement en mode va-et-vient (où l'entraîneur peut prendre les deux positions stables illustrées respectivement sur les figures 10 et 13).The user also switches the driver 226 into its position where the finger 227 formed on the driver 226 compresses the compressible element 250 until the flange 256 of the compressible element 250 passes behind the lug 219 formed on the arm 217 and that the retaining element formed by the arm 217 provided with the lug 219 thus retains the compressible element 250 in its inactive position vis-à-vis the driver 226: the electrical switch 200 finds its configuration allowing operation in back-and-forth mode (where the coach can take the two stable positions illustrated respectively on the figures 10 and 13 ).

On peut prévoir que l'utilisateur exerce simultanément l'action de déplacement de l'extrémité libre du bras 217 (représentée en figure 12) et l'action de basculement de l'entraîneur 226 dans sa position représentée en figure 13 afin de revenir dans la configuration en mode va-et-vient.Provision may be made for the user to simultaneously exercise the movement action of the free end of the arm 217 (shown in figure 12 ) and the tilting action of the driver 226 in its position shown in figure 13 in order to return to the configuration in back-and-forth mode.

On peut également prévoir de positionner et de dimensionner le bras 217 de telle sorte qu'après que l'extrémité libre du bras 217 a passé le bord arrière de la fenêtre 211 (sous l'effet de l'outil 400) comme représenté en figure 12, le bras 217 se trouve dans sa position où il est apte à retenir l'élément compressible 250, et que le passage de la collerette 256 contre l'ergot 219 (du fait du basculement de l'entraîneur 226 par l'utilisateur) ne provoque pas un effort suffisant pour que le bras 217 retourne, à travers la fenêtre 211, dans sa position illustrée en figure 11.It is also possible to provide for positioning and dimensioning the arm 217 so that after the free end of the arm 217 has passed the rear edge of the window 211 (under the effect of the tool 400) as shown in figure 12 , the arm 217 is in its position where it is able to retain the compressible element 250, and that the passage of the flange 256 against the lug 219 (due to the tilting of the driver 226 by the user) does not cause a sufficient effort for the arm 217 to return, through the window 211, to its position illustrated in figure 11 .

Le retour dans la configuration en mode va-et-vient peut alors se faire en deux étapes distinctes : le déplacement de l'extrémité libre du bras 217 au-delà du bord arrière de la fenêtre 211 comme représenté en figure 12, puis la compression de l'élément compressible 250 par basculement de l'entraîneur 226 comme représenté en figure 13 (le bras 217 restant dans sa position où il est apte à retenir l'élément compressible 250 même lors du passage de la collerette 256 au contact de l'ergot 219).The return to the configuration in back-and-forth mode can then be done in two distinct stages: the displacement of the free end of the arm 217 beyond the rear edge of the window 211 as shown in figure 12 , then the compression of the compressible element 250 by tilting the driver 226 as shown in figure 13 (the arm 217 remaining in its position where it is capable of retaining the compressible element 250 even when the flange 256 passes in contact with the lug 219).
