Description

La présente invention concerne le domaine des contacteurs électriques et a pour objet un dispositif de contacteur à clé ou autre élément amovible.The present invention relates to the field of electrical contactors and relates to a key switch device or other removable element.

On connaît déjà des contacteurs à clé, ou autre élément amovible, dont la clé est insérée dans un cylindre de serrure ne disposant que d'une entrée de clé, communément appelé demi-cylindre de serrure, monté dans un boîtier et ensuite tournée pour solliciter ou actionner au moins un interrupteur permettant l'ouverture ou la fermeture d'un circuit électrique.Key switches, or other removable element, whose key is inserted into a lock cylinder having only a key input, commonly called a lock half-cylinder, mounted in a housing and then turned to solicit, are already known. or operate at least one switch for opening or closing an electrical circuit.

Parmi ces contacteurs à clé, certains sont prévus avec deux interrupteurs, disposés symétriquement par rapport à un plan contenant l'axe du demi-cylindre, donnant deux positions de commutation et partant deux positions de rotation de la clé généralement indiquées par des sigles ou des figures apposées sur la face avant du boîtier. Chaque position de commutation permet de commander, par exemple, l'entraînement électrique en ouverture ou en fermeture d'une porte ou d'un portail ou la montée ou la descente d'un volet électrique.Among these key switches, some are provided with two switches arranged symmetrically with respect to a plane containing the axis of the half-cylinder, giving two switching positions and therefore two key rotation positions generally indicated by acronyms or symbols. figures affixed to the front of the case. Each switching position can control, for example, the electric drive opening or closing a door or gate or the rise or fall of an electric shutter.

Dans ce type de contacteur à clé comportant deux interrupteurs l'une des deux positions de commutation est atteinte, depuis une position neutre ou centrale du demi-cylindre de serrure où la clé peut être enfichée dans ou extraite de ce dernier, en tournant la clé dans un sens, tandis que l'autre position de commutation est obtenue en tournant la clé dans le sens inverse.In this type of key switch comprising two switches one of the two switch positions is reached, from a neutral or central position of the lock half-cylinder where the key can be plugged into or extracted from the latter, by turning the key. in one direction, while the other switching position is obtained by turning the key in the opposite direction.

Le document EP 1 263 010 décrit un contacteur à clé avec commande à câble pour des entraînements électriques de portes ou de portails, comprenant une serrure à demi-cylindre fixée dans une ouverture d'une plaque frontale amovible d'un boîtier et comportant un demi-cylindre de fermeture dans lequel une clé peut être enfichée ou extraite dans une position neutre ou centrale déterminée. D'autre part, le demi-cylindre de fermeture présente un panneton interrupteur mobile en pivotement au moyen de la clé de sorte à venir solliciter deux interrupteurs électriques situés dans un même plan perpendiculaire à l'axe de rotation du demi-cylindre et symétriquement de part et d'autre de l'axe de rotation de ce dernier.The document EP 1 263 010 discloses a cable-operated key switch for electric drives for doors or gates comprising a half-cylinder lock secured in an opening of a removable front plate of a housing and having a closing half-cylinder in which a key can be plugged in or extracted in a neutral or central position determined. On the other hand, the closing half cylinder has a switch bit pivotally movable by means of the key so as to come to solicit two electrical switches located in the same plane perpendicular to the axis of rotation of the half-cylinder and symmetrically on both sides of the axis of rotation of the latter.

En outre, ces contacteurs à clé sont conçus pour fonctionner en mode permanent, c'est-à-dire qu'au moment du relâchement de l'interrupteur, celui-ci reste dans sa dernière position de commutation, ou en mode momentané ou impulsionnel, c'est-à-dire qu'au moment du relâchement de l'interrupteur, celui-ci reprend sa position initiale de non commutation. Ainsi, pour passer d'un mode de fonctionnement, permanent ou momentané à un autre, il est nécessaire de changer de contacteur.In addition, these key switches are designed to operate in permanent mode, that is to say that at the moment of release of the switch, it remains in its last switch position, or momentary or pulsed , that is to say that at the time of release of the switch, it returns to its original position of non-switching. Thus, to switch from one mode of operation, permanent or momentary to another, it is necessary to change the contactor.

Par ailleurs, un contacteur à clé actuel à deux interrupteurs présente un encombrement important qui nécessite un boîtier avec des dimensions, notamment au niveau de sa largeur, ne permettant pas son implantation dans un cadre ou un profilé de porte ou de fenêtre. Un autre contacteur à clé est connu du document DE 3104103 .Furthermore, a current key switch with two switches has a large footprint that requires a housing with dimensions, especially at its width, not allowing its implementation in a frame or a section of a door or window. Another key switch is known from the document DE 3104103 .

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de contacteur à clé modulable permettant d'être facilement transformable en mode de fonctionnement permanent ou momentané, tout en offrant, le cas échéant, une plus grande compacité, plus particulièrement dans le sens de la largeur du boîtier, que les contacteur à clé actuels afin de permettre, par exemple, son implantation dans un cadre ou profilé de porte ou de fenêtre.The present invention aims to overcome these disadvantages by providing a modular key switch device to be easily converted into permanent or momentary operation mode, while offering, where appropriate, greater compactness, particularly in the direction of the width of the housing, the current key switch to allow, for example, its implementation in a frame or profile of door or window.

A cet effet, la présente invention a pour objet un dispositif de contacteur à clé comprenant un boîtier comportant deux faces opposées, à savoir respectivement une face avant et un fond, reliées entre elles par des faces latérales, et renfermant, d'une part, un demi-cylindre de serrure monté en rotation axiale autour d'un axe de rotation sous l'effet de la rotation d'une clé enfichée dans ledit demi-cylindre de serrure du côté face avant dudit boîtier et un panneton solidaire dudit demi-cylindre et, d'autre part, un ensemble de commutation comportant au moins un interrupteur configuré en mode momentané,
contacteur se caractérisant essentiellement en ce que ledit panneton est apte, lors de sa rotation, à entraîner en déplacement rectiligne, transversalement à l'axe de rotation dudit demi-cylindre de serrure, un chariot mobile comportant au moins une surface de sollicitation susceptible de venir, par le déplacement du chariot mobile, en contact avec l'interrupteur ou l'un des interrupteurs de sorte à solliciter ce dernier de façon permanente ou, le cas échéant, de façon momentanée grâce à des moyens de rappel amovibles permettant de faire revenir automatiquement le chariot mobile jusqu'à une position neutre ou centrale de non sollicitation.For this purpose, the subject of the present invention is a key contactor device comprising a housing comprising two opposite faces, namely respectively a front face and a base, connected together by lateral faces, and enclosing, on the one hand, a half-cylinder lock mounted in axial rotation about an axis of rotation under the effect of the rotation of a key plugged into said lock half-cylinder on the front side of said housing and a bit secured to said half-cylinder and, on the other hand, a switching assembly comprising at least one switch configured in a momentary mode,
contactor characterized essentially in that said bit is adapted, during its rotation, to drive in rectilinear displacement, transversely to the axis of rotation of said lock half-cylinder, a movable carriage having at least one bias surface likely to come by moving the movable carriage, in contact with the switch or one of the switches so as to solicit the latter permanently or, where appropriate, momentarily by means of removable return means for returning automatically the carriage movable to a neutral or central non-solicitation position.

Les figures montrent un dispositif de contacteur à clé, selon la présente invention, comprenant un boîtier 1 comportant deux faces opposées, à savoir respectivement une face avant 8 et un fond 14, reliées entre elles par des faces latérales 19, et renfermant, d'une part, un demi-cylindre de serrure 2 monté en rotation axiale autour d'un axe de rotation 2' sous l'effet de la rotation d'une clé enfichée dans ledit demi-cylindre de serrure 2 du côté face avant 8 dudit boîtier 1 et un panneton 3 solidaire dudit demi-cylindre 2 et, d'autre part, un ensemble de commutation 4 comportant au moins un interrupteur 5, 5' configuré en mode momentané.The figures show a key switch device, according to the present invention, comprising a housing 1 comprising two opposite faces, namely respectively a front face 8 and a bottom 14, interconnected by side faces 19, and enclosing, d ' firstly, a half cylinder lock 2 mounted in axial rotation about an axis of rotation 2 'under the effect of the rotation of a key plugged into said lock half-cylinder 2 of the front side 8 of said housing 1 and a bit of solidarity 3 said half-cylinder 2 and, secondly, a switching assembly 4 comprising at least one switch 5, 5 'configured in momentary mode.

Conformément à la présente invention dans un tel contacteur le panneton 3 est apte, lors de sa rotation, à entraîner en déplacement rectiligne, transversalement à l'axe de rotation 2' dudit demi-cylindre de serrure 2, un chariot mobile 6 comportant au moins une surface de sollicitation 7, 7' susceptible de venir, par le déplacement du chariot mobile 6 dans un certain sens ou en sens inverse selon le sens et le degré de rotation de la clé, en contact avec l'interrupteur ou l'un des interrupteurs 5, 5' de sorte à solliciter ce dernier de façon permanente ou, le cas échéant, de façon momentanée grâce à des moyens de rappel 16 amovibles permettant de faire revenir automatiquement le chariot mobile 6 jusqu'à une position neutre ou centrale de non sollicitation.According to the present invention in such a contactor the bit 3 is adapted, during its rotation, to drive in rectilinear displacement, transversely to the axis of rotation 2 'of said lock half-cylinder 2, a movable carriage 6 comprising at least a biasing surface 7, 7 'may come, by moving the movable carriage 6 in a certain direction or in the opposite direction depending on the direction and degree of rotation of the key, in contact with the switch or one of switches 5, 5 'so as to solicit the latter permanently or, where appropriate, momentarily by means of removable biasing means 16 for automatically return the movable carriage 6 to a neutral or central position of no solicitation.

De manière à optimiser la compacité du dispositif de contacteur à clé selon la présente invention, notamment dans le sens de la largeur du boîtier 1, le demi-cylindre de serrure 2, le chariot mobile 6 et l'ensemble de commutation 4 peuvent être avantageusement montés successivement à l'intérieur du boîtier 1 suivant un axe sensiblement perpendiculaire à l'axe de rotation 2' du demi-cylindre de serrure 2.In order to optimize the compactness of the key switch device according to the present invention, in particular in the direction of the width of the housing 1, the lock half-cylinder 2, the movable carriage 6 and the switching assembly 4 can be advantageously successively mounted inside the housing 1 along an axis substantially perpendicular to the axis of rotation 2 'of the lock half-cylinder 2.

On comprendra alors que dans une orientation verticale du boîtier 1, le demi-cylindre de serrure 2, le chariot mobile 6 et l'ensemble de commutation 4 seront orientés verticalement les uns au-dessus des autres avec de préférence le demi-cylindre de serrure au niveau le plus bas et l'ensemble de commutation 4 au niveau le plus haut (figures 1, 2a, 3a et 4).It will then be understood that in a vertical orientation of the housing 1, the lock half-cylinder 2, the movable carriage 6 and the switching assembly 4 will be oriented vertically one above the other with preferably the lock half-cylinder. at the lowest level and the switching unit 4 at the highest level ( figures 1 , 2a , 3a and 4 ).

Dans un mode de réalisation préférentiel de la présente invention, l'ensemble de commutation 4 peut comporter deux interrupteurs 5 et 5' situés, à l'état monté, respectivement dans deux plans différents et perpendiculaires audit axe de rotation 2' et sensiblement symétriquement par rapport à un plan contenant l'axe de rotation 2' du demi-cylindre de serrure 2 et le chariot mobile 6 peut comporter deux surfaces de sollicitation 7 et 7' situées chacune, à l'état monté, dans l'un desdits plans (figure 1).In a preferred embodiment of the present invention, the switching assembly 4 may comprise two switches 5 and 5 'situated, in the mounted state, respectively in two different planes and perpendicular to said axis of rotation 2' and substantially symmetrically by relative to a plane containing the axis of rotation 2 'of the lock half-cylinder 2 and the movable carriage 6 may comprise two biasing surfaces 7 and 7' each located, in the mounted state, in one of said planes ( figure 1 ).

De préférence de manière à optimiser encore la compacité du contacteur, notamment dans le sens de la largeur du boîtier 1, les deux interrupteurs 5 et 5' peuvent avantageusement être alignés ou presque alignés sensiblement parallèlement à l'axe de rotation 2' du demi-cylindre de serrure 2.Preferably so as to further optimize the compactness of the contactor, particularly in the direction of the width of the housing 1, the two switches 5 and 5 'can advantageously be aligned or almost aligned substantially parallel to the axis of rotation 2' of the half lock cylinder 2.

Par ailleurs, de préférence, la ou chaque surface de sollicitation 7, 7' peut être constituée successivement par une première partie d'amorçage, consistant de préférence en une pente, de la sollicitation de l'interrupteur ou de l'un des interrupteurs 5, 5' correspondant et par une seconde partie de sollicitation permanente de ce dernier.Furthermore, preferably, the or each biasing surface 7, 7 'may be constituted successively by a first priming portion, preferably consisting of a slope, of the biasing of the switch or of one of the switches 5 , 5 'corresponding and a second part of permanent solicitation of the latter.

D'autre part, plus particulièrement dans le cas ou le ou chaque interrupteur 5, 5' présente un profil arrondi, la ou chaque partie d'amorçage peut consister en une arête ou une partie arrondie.On the other hand, more particularly in the case where the or each switch 5, 5 'has a rounded profile, the or each priming portion may consist of an edge or a rounded portion.

Le cas échéant, lorsque l'ensemble de commutation 4 comporte deux interrupteurs 5 et 5', le chariot mobile 6 peut comprendre deux surfaces de sollicitation 7, 7', dont les deux parties d'amorçage respectives, de préférence en pente, s'étendent ou sont orientées de façon antagoniste entre elles de sorte que l'une des deux partie d'amorçage en pente soit apte à solliciter l'un des deux interrupteurs 5 ou 5', lors du déplacement du chariot mobile 6 dans un certain sens et que l'autre partie d'amorçage en pente soit apte à solliciter l'autre interrupteur 5 ou 5' lors du déplacement du chariot mobile 6 dans un sens inverse (figure 4 et figure 6).Where appropriate, when the switching assembly 4 comprises two switches 5 and 5 ', the mobile carriage 6 may comprise two biasing surfaces 7, 7', the two respective priming portions, preferably inclined, s' extend or are oriented in an antagonistic manner with each other so that one of the two sloping priming portions is able to urge one of the two switches 5 or 5 ', during the displacement of the movable carriage 6 in a certain direction and that the other sloping priming portion is able to urge the other switch 5 or 5 'during the displacement of the movable carriage 6 in a reverse direction ( figure 4 and figure 6 ).

De préférence, le chariot mobile 6 peut être monté en déplacement dans le boîtier 1 par coulissement grâce à un mécanisme de glissière 9, 10 et peut comporter au moins une face de contact et d'entraînement 11, 11' positionnée transversalement sur la trajectoire circulaire du panneton 3 de sorte que celui-ci puisse venir, lors de sa rotation, en contact avec la ou l'une desdites face(s) et entraîner le chariot mobile 6 en coulissement.Preferably, the movable carriage 6 can be mounted in displacement in the housing 1 by sliding thanks to a slide mechanism 9, 10 and can comprise at least one contact and drive face 11, 11 'positioned transversely on the circular path bit 3 so that it can come, during its rotation, in contact with one or one of said face (s) and drive the movable carriage 6 in sliding.

Dans un mode de réalisation préférentiel du chariot mobile 6, comme on peut le voir sur les figures 4 et 6, celui-ci peut présenter la forme d'un parallélépipède rectangle, comprenant deux faces latérales 11 et 11' opposées constituant chacune une face de contact et d'entraînement, deux faces latérales 13 et 13' opposées et deux bases 12 et 12' opposées, dont l'une d'entre elle ou base 12 de sollicitation comporte au moins une surface de sollicitation 7, 7'.In a preferred embodiment of the mobile carriage 6, as can be seen in the figures 4 and 6 it may have the shape of a rectangular parallelepiped, comprising two opposite side faces 11 and 11 'each constituting a contact and driving face, two opposite side faces 13 and 13' and two opposing bases 12 and 12 ' , one of them or base 12 of biasing comprises at least one biasing surface 7, 7 '.

D'autre part, de manière à obtenir un contact plus efficace entre le panneton 3 et l'une ou l'autre des deux faces de contact et d'entraînement 11 et 11', selon le sens et le degré de rotation du panneton 3, ces dernières peuvent de préférence être inclinées vers l'intérieur du chariot mobile 6, depuis la base 12 de sollicitation jusqu'à l'autre base 12' opposée.On the other hand, so as to obtain a more effective contact between the bit 3 and one or other of the two contact and drive surfaces 11 and 11 ', according to the direction and degree of rotation of the bit 3 , these last can preferably be inclined inwardly of the movable carriage 6, from the biasing base 12 to the other opposite base 12 '.

Dans une forme de réalisation préférentielle, la base 12 de sollicitation du chariot mobile 6 peut comprendre au moins une gorge 21, 21' s'étendant, à l'état monté, parallèlement au sens de déplacement du chariot mobile 6 et étant apte à recevoir l'interrupteur ou l'un des interrupteurs 5, 5' correspondant. En outre, le fond de la ou de chaque gorge 21, 21' peut être conformée, au moins en partie, en pente vers un point de la base 12 de sollicitation, situé en retrait de l'une des deux faces de contact et d'entraînement 11, 11' opposées. La ou chaque pente forme alors la première partie d'amorçage et la face externe de la base 12 de sollicitation, s'étendant entre la pente et la face de contact et d'entraînement 11, 11' correspondantes, forme alors la seconde partie de sollicitation permanente de la surface de sollicitation ou de l'une des surfaces de sollicitation 7, 7' correspondants.In a preferred embodiment, the base 12 for biasing the mobile carriage 6 may comprise at least one groove 21, 21 'extending, in the mounted state, parallel to the direction of movement of the movable carriage 6 and being able to receive the switch or one of the corresponding switches 5, 5 '. In addition, the bottom of the or each groove 21, 21 'may be shaped, at least in part, sloping towards a point of the biasing base 12, set back from one of the two contact faces and 11,11 'drive opposite. The or each slope then forms the first priming portion and the outer face of the biasing base 12, extending between the slope and the corresponding contact and driving face 11, 11 ', then forms the second part of permanent urging of the biasing surface or one of the corresponding biasing surfaces 7, 7 '.

De manière à assurer le coulissement du chariot mobile 6, dans une forme de réalisation préférentielle, les deux faces latérales 13 et 13' opposées peuvent comporter chacune une première partie de glissière 9, de préférence du type rainure ou nervure, s'étendant parallèlement à la base 12 de sollicitation et étant apte à coopérer en glissement et en coulissement avec une seconde partie de glissière 10 complémentaire, de préférence du type rainure ou nervure, intégrée dans le boîtier 1 ou dans un insert 15 rapporté dans le boîtier 1 et fixé dans ce dernier par des moyens de fixation 23, par exemple, par vissage (figures 1, 4 et 6).In order to ensure the sliding of the mobile carriage 6, in a preferred embodiment, the two opposite lateral faces 13 and 13 'may each comprise a first slide portion 9, preferably of the groove or rib type, extending parallel to the base 12 of biasing and being able to cooperate in sliding and sliding with a second portion of complementary slide 10, preferably of the groove or rib type, integrated in the housing 1 or in an insert 15 in the housing 1 and fixed in the latter by fixing means 23, for example, by screwing ( figures 1 , 4 and 6 ).

De préférence, l'une des deux secondes parties de glissière 10, du type rainure ou nervure, peut être pratiquée dans le fond 14 du boîtier 1 perpendiculairement à l'axe de rotation 2' du demi-cylindre de serrure et l'autre seconde partie de glissière 10 peut être intégrée dans un insert 15 se présentant sous la forme d'une plaque, de préférence une plaque rectangulaire, dans l'une des grandes faces de laquelle est pratiquée l'autre seconde partie de glissière 10, du type rainure ou nervure. La plaque 15 peut s'étendre dans le boîtier 1 entre le fond 14 et la face avant 8 perpendiculairement à l'axe 2' du demi-cylindre de serrure 2.Preferably, one of the two second slider portions 10, of the groove or rib type, can be made in the bottom 14 of the housing 1 perpendicular to the axis of rotation 2 'of the lock half-cylinder and the other second Slide part 10 can be integrated in an insert 15 in the form of a plate, preferably a rectangular plate, in one of the large faces of which is formed the other second slide portion 10, of the groove type. or rib. The plate 15 can extend in the housing 1 between the bottom 14 and the front face 8 perpendicularly to the axis 2 'of the lock half-cylinder 2.

Dans une forme de réalisation préférentiel des moyens de rappel, ceux-ci peuvent consister en un ressort à lame(s) 16 fixé de façon amovible, de préférence sensiblement perpendiculairement à l'axe de rotation 2' du demi-cylindre de serrure 2, d'une part, par une première partie de fixation, de préférence l'une de ses extrémités, sur le chariot mobile 6 et, d'autre part, par une seconde partie de fixation, éloignée de ladite première partie de fixation, sur un point fixe situé à l'intérieur du boîtier 1 (figure 4 et figure 5a).In a preferred embodiment of the return means, these may consist of a leaf spring (s) 16 removably fixed, preferably substantially perpendicular to the axis of rotation 2 'of the lock half-cylinder 2, on the one hand, by a first fixing part, preferably one of its ends, on the movable carriage 6 and, secondly, by a second attachment part, remote from said first fixing part, on a fixed point located inside the case 1 ( figure 4 and figure 5a ).

Plus particulièrement, la présente invention peut prévoir que le ressort à lame 16 soit fixé, par l'une de ses extrémités, le cas échéant, sur la base 12' du chariot libre 6 de forme globalement parallélépipédique rectangle, opposée à la base 12 de sollicitation, par l'intermédiaire d'un premier étrier 17 et que la seconde partie de fixation du ressort à lame 16 soit fixée sur le fond 14 du boîtier 1 par l'intermédiaire d'un second étrier 18. Le premier étrier 17 et/ou le second étrier 18 peuvent avantageusement être associé à des moyens de maintien en assemblage 17', du type par exemple broche ou goupille 17', avec la première ou seconde partie de fixation correspondante du ressort à lame 16.More particularly, the present invention can provide that the leaf spring 16 is fixed, by one of its ends, if necessary, on the base 12 'of the free carriage 6 of generally rectangular parallelepiped shape, opposite to the base 12 of biasing, through a first yoke 17 and that the second fastening portion of the leaf spring 16 is fixed to the bottom 14 of the housing 1 via a second yoke 18. The first yoke 17 and / or the second stirrup 18 may advantageously be associated with assembly holding means 17 ', of the type for example pin or pin 17', with the corresponding first or second fixing portion of the leaf spring 16.

De préférence un tel assemblage de maintien peut être effectué à l'aide seule d'une goupille 17' traversant la première partie de fixation du ressort à lame 16 et le premier étrier 17 fixé sur le chariot mobile 6 (figure 4), tandis que la seconde partie de fixation du ressort à lame 16 peut être insérée simplement dans le second étrier 18 fixé sur le fond 14 du boîtier 1, ce afin de rendre encore plus aisé et plus rapide la mise en place du ressort à lame 16 dans le boîtier 1 et partant l'opération de changement du mode de fonctionnement, permanent ou momentané, du dispositif selon la présente invention.Preferably, such a holding assembly can be made using only a pin 17 'passing through the first fastening portion of the leaf spring 16 and the first yoke 17 fixed to the movable carriage 6 ( figure 4 ), while the second fixing portion of the leaf spring 16 can be inserted simply into the second yoke 18 fixed on the bottom 14 of the housing 1, in order to make it even easier and faster to install the leaf spring 16 in the housing 1 and therefore the operation of changing the mode of operation, permanent or momentary, the device according to the present invention.

En outre, de manière à empêcher ou à limiter les oscillations du ressort à lame 16 lors de son rappel en position de repos, la présente invention peut prévoir avantageusement un moyen d'amortissement, non représenté, tel que par exemple un relief ou un bossage pratiquée dans le fond 14 du boîtier 1 venant au contact avec frottement avec le ressort à lame 16 en position de repos de ce dernier ou un élément rapporté tel qu'une bille fixée sur le fond 14 et venant en contact avec frottement avec ledit ressort.In addition, so as to prevent or limit the oscillations of the leaf spring 16 when returning to the rest position, the present invention can advantageously provide a damping means, not shown, such as for example a relief or a boss formed in the bottom 14 of the housing 1 coming into frictional contact with the leaf spring 16 in the rest position of the latter or an insert such as a ball fixed on the bottom 14 and coming into frictional contact with said spring.

Par ailleurs si on se réfère à la figure 4 on peut voir que la face avant 8 du boîtier 1, qui peut être fixée de façon amovible sur ce dernier grâce à des vis 20, peut comporter un capot de protection 8' permettant également de cacher les vis 20.Moreover, if we refer to the figure 4 it can be seen that the front face 8 of the housing 1, which can be detachably fixed to the latter by means of screws 20, can comprise a protective cover 8 'which also makes it possible to hide the screws 20.

En outre la face visible de la face avant 8, le cas échéant 8', peut comporter, dans le cas d'un ensemble de commutation 4 comportant deux interrupteurs 5 et 5', deux repères 22 ou sigles, par exemple, deux triangles ou flèches inversés, marquant deux positions de rotation de la clé (figures 2b et 3b) correspondant chacune à une position de sollicitation de l'un des deux interrupteurs 5 ou 5' permettant de commander, par exemple, l'entraînement électrique en ouverture ou en fermeture d'une porte ou d'un portail ou la montée ou la descente d'un volet électrique.In addition, the visible face of the front face 8, where appropriate 8 ', may include, in the case of a switching assembly 4 comprising two switches 5 and 5 ', two marks 22 or acronyms, for example, two triangles or inverted arrows, marking two positions of rotation of the key ( figures 2b and 3b ) each corresponding to a biasing position of one of the two switches 5 or 5 'for controlling, for example, the electric drive opening or closing a door or gate or the ascent or descent an electric shutter.

Ainsi grâce à un dispositif de contacteur à clé, selon la présente invention, il est possible de modifier le mode de fonctionnement du ou des interrupteurs 5, 5' initialement configurés chacun en mode momentané, soit dans un mode de fonctionnement permanent, lorsque le chariot mobile 6 n'est pas associé à des moyens de rappel 16 amovible, laissant, après relâchement, le chariot mobile 6 en position de sollicitation, soit dans un mode de fonctionnement momentané ou impulsionnel, lorsque le chariot mobile 6 est associé à des moyens de rappel 16, rappelant, après relâchement, le chariot mobile 6 dans une position neutre ou centrale de non sollicitation.Thus, thanks to a key switch device, according to the present invention, it is possible to modify the operating mode of the switch or switches 5, 5 'initially configured each momentarily, or in a permanent operating mode, when the carriage mobile 6 is not associated with removable return means 16, leaving, after release, the movable carriage 6 in the biasing position, either in a momentary or momentary operating mode, when the movable carriage 6 is associated with means of recall 16, recalling, after release, the movable carriage 6 in a neutral or central non-solicitation position.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
