Abstract

Remote-control interrupter of the type comprising an auxiliary change-over switch interposed between the coil of the said interrupter and two parallel control conductors. The prop (5a) for the moving contact of this auxiliary change-over switch is mounted pivotably on the moving prop (3a) for the main contacts of this interrupter. Elastic thrusting means tend to ensure stability of the prop (5a) for the moving contact of the switch in each of its positions. However the arrangement is such that the kinematics of this prop (5a) includes two separate axes of tilt (C-D and E-F) which lie on either side of the axis of tilt (A-B) of the mechanism of the interrupter. Thus, the tilting of this prop (5a) into a new position can thus take place only after tilting of the mechanism of the interrupter. This interrupter can be employed for any of the usual uses of interrupters of this type. <IMAGE>

Description

Contrairement aux contacteurs, les télérupteurs possèdent deux positions stables. Ils sont habituellement commandés par des impulsions qui alimentent leur électro­aimant ; lequel, par l'intermédiaire d'un mécanisme approprié, inverse la position des contacts à commander.Unlike contactors, the remote control switches have two stable positions. They are usually controlled by pulses which feed their electromagnet; which, by means of an appropriate mechanism, reverses the position of the contacts to be controlled.

Grâce à la commande par impulsions, les télérupteurs présentent, par rapport aux contacteurs, l'avantage de ne pas nécessiter le maintien d'un courant dans le bobinage.Thanks to the impulse control, the remote switches have, compared to the contactors, the advantage of not requiring the maintenance of a current in the winding.

Par contre, dans le cas d'une commande à distance, on n'est pas toujours en mesure de connaître la position des contacts, à moins d'utiliser un voyant de contrôle.On the other hand, in the case of a remote control, it is not always able to know the position of the contacts, unless using a control lamp.

Un autre inconvénient des télérupteurs, apparait lorsqu'ils sont couplés en parallèle, c'est-à-dire lorsqu'un poussoir est raccordé à plusieurs télérupteurs. Dans ce cas, il arrive, lorsque les impulsions de commande sont trop brèves, que certains télérupteurs ne basculent pas, alors que les autres basculent normalement, les temps de réponse pouvant être légèrement différents. Dans ce cas, les contacts de télérupteurs ne se trouvant plus en concordance, il peut en résulter des désordres graves et en tous cas, la nécessité de faire intervenir un professionnel pour le dépannage.Another drawback of remote control switches appears when they are coupled in parallel, that is to say when a pushbutton is connected to several remote control switches. In this case, it happens, when the control pulses are too short, that certain remote control switches do not switch, while the others switch normally, the response times may be slightly different. In this case, the contacts of the remote control switches no longer being in agreement, it can result in serious disorders and in any case, the need to call in a professional for troubleshooting.

Pour pallier ces inconvénients, il a été imaginé de munir les télérupteurs d'un inverseur auxiliaire inséré sur son circuit de commande de façon à assurer cette commande par l'un ou l'autre de deux conducteurs distincts comportant respectivement un poussoir de mise en marche et un poussoir d'arrêt, cet inverseur étant lui même actionné par le mécanisme du télérupteur lors du fonctionnement de celui-ci. Ainsi, un tel télérupteur interrompt lui-même l'impulsion qui provoque son basculement, dans un sens ou dans l'autre.To overcome these drawbacks, it has been imagined to provide the remote control switches with an auxiliary inverter inserted on its control circuit so as to ensure this control by one or the other of two conductors separate respectively comprising a start button and a stop button, this inverter itself being actuated by the mechanism of the remote control switch during operation thereof. Thus, such a remote control switch itself interrupts the pulse which causes its tilting, in one direction or the other.

Dans un tel télérupteur, l'impulsion envoyée dans l'un des conducteurs de commande, à partir du poussoir de mise en marche, provoque la fermeture des contacts principaux, alors que l'impulsion envoyée dans l'autre conducteur, à partir du poussoir "arrêt", provoque l'ouverture de ces mêmes contacts. C'est l'énergie cinétique de l'ensemble des pièces en mouvement qui permet alors le passage du point mort du mécanisme du télérupteur et l'achèvement de la course des organes mobiles.In such a remote control switch, the pulse sent in one of the control conductors, from the start button, causes the main contacts to close, while the pulse sent in the other conductor, from the push button "stop", causes the opening of these same contacts. It is the kinetic energy of all the moving parts which then allows the neutral point of the remote control mechanism to pass and the travel of the moving parts to be completed.

Cependant il peut arriver qu'une impulsion de commande, très brève, ne fournisse pas l'énergie nécessaire au franchissement du point mort. Si, dans un tel cas, certains télérupteurs venaient à se décaler, l'impulsion suivante, de durée correcte, les recalerait. En effet, seuls les télérupteurs n'ayant pas été inversés recevraient l'impulsion de commande.However, it may happen that a very short command pulse does not provide the energy necessary to cross neutral. If, in such a case, certain remote control switches were to shift, the next pulse, of correct duration, would readjust them. In fact, only the remote control switches that have not been inverted would receive the control pulse.

Toutefois, lors des impulsions trop brèves, il peut arriver que l'inverseur auxiliaire, commandant la bobine du télérupteur, s'immobilise dans sa position de point mort. Cela se produit lorsque la durée de l'impulsion correspond exactement à l'énergie nécessaire pour amener le mécanisme du télérupteur à son point mort. Dans un tel cas les deux contacts de l'inverseur se trouvant alors coupés simultanément. En conséquence, le télérupteur se trouve immobilisé dans cette position et on est dans l'impossibilité de le manoeuvrer électriquement.However, during too short pulses, it may happen that the auxiliary inverter, controlling the coil of the remote control switch, stops in its neutral position. This occurs when the duration of the pulse corresponds exactly to the energy necessary to bring the mechanism of the remote control switch to neutral. In such a case, the two contacts of the reverser then being cut simultaneously. Consequently, the remote control switch is immobilized in this position and it is impossible to operate it electrically.

Les soins que l'on apporte à la fabrication d'un tel appareil peuvent réduire ce risque, mais ne peuvent pas le supprimer complètement ; en effet les ressorts qui assurent le basculement et la stabilité des deux positions extrêmes deviennent inopérants au passage du point mort, car ils provoquent au contraire des frottements qui sont à leur maximum et qui favorisent une immobilisation dans cette position.The care taken in manufacturing such a device can reduce this risk, but cannot completely eliminate it; indeed the springs which ensure the tilting and the stability of the two extreme positions become ineffective when passing from neutral, because on the contrary they cause friction which is at its maximum and which favors immobilization in this position.

C'est pourquoi la présente invention a pour but de réaliser un télérupteur du type en cause, c'est-à-dire un télérupteur pourvu d'un inverseur auxiliaire, dont la conception est telle que le mécanisme de celui-ci ne peut en aucune façon se trouver immobilisé dans la position d'ouverture des deux contacts de cet inverseur.This is why the object of the present invention is to produce a remote control switch of the type in question, that is to say a remote control switch provided with an auxiliary reverser, the design of which is such that the mechanism thereof cannot no way to be immobilized in the open position of the two contacts of this change-over.

A cet effet le télérupteur selon l'invention est caractérisé en ce que
- le support du contact mobile de son inverseur auxiliaire est monté pivotant sur le support mobile des contacts principaux de ce télérupteur entre deux positions distinctes de fermeture déterminées par le déplacement de ce support mobile dans un sens ou dans l'autre,
- des moyens élastiques de poussée tendent à assurer la stabilité du support du contact mobile de l'inverseur dans chacune de ces positions,
- mais l'agencement est tel que la cinématique de ce support comporte deux axes distincts de basculement, qui sont situés de part et d'autre de l'axe de basculement du mécanisme du télérupteur,
- et que le basculement de ce support dans une nouvelle position de fermeture ne peut avoir lieu qu'après basculement du mécanisme du télérupteur.To this end, the remote control switch according to the invention is characterized in that
the support of the mobile contact of its auxiliary change-over is pivotally mounted on the mobile support of the main contacts of this remote control switch between two distinct closing positions determined by the movement of this mobile support in one direction or the other,
elastic thrust means tend to ensure the stability of the support of the movable contact of the reverser in each of these positions,
- but the arrangement is such that the kinematics of this support comprises two distinct tilting axes, which are located on either side of the tilting axis of the remote control mechanism,
- And that the tilting of this support in a new closed position can only take place after the tilting mechanism of the remote control switch.

Dans ces conditions, il ne peut donc y avoir en aucune façon immobilisation du support du contact mobile de l'inverseur auxiliaire dans une position d'ouverture de celui-ci.Under these conditions, there can therefore be no immobilization of the support of the movable contact of the auxiliary inverter in an open position thereof.

Dans une forme de réalisation avantageuse du présent télérupteur, le support du contact mobile de son inverseur auxiliaire est constitué par un bras monté pivotant sur le support mobile des contacts principaux et formant un système à genouillère avec un élément portant un ressort de poussée et dont l'extrémité opposée s'articule elle-même sur le support mobile des contacts principaux, cependant que les contacts fixes de l'inverseur sont disposés de part et d'autre de l'axe de basculement du mécanisme du télérupteur.In an advantageous embodiment of this remote control switch, the support of the movable contact of its auxiliary change-over is constituted by an arm pivotally mounted on the movable support of the main contacts and forming a toggle system with an element carrying a thrust spring and whose l the opposite end is articulated on the movable support of the main contacts, while the fixed contacts of the reverser are arranged on either side of the tilting axis of the remote control mechanism.

Le mécanisme ainsi constitué présente une très grande fiabilité de fonctionnement. Par ailleurs son installation à l'intérieur du télérupteur correspondant est très facile à réaliser.The mechanism thus formed has a very high operating reliability. Furthermore, its installation inside the corresponding remote control switch is very easy to perform.

Cependant d'autres particularités et avantages du télérupteur selon l'invention apparaîtront au cours de la description suivante. Celle-ci est donnée en référence au dessin annexé à simple titre indicatif, et sur lequel :

  • La figure 1 représente le schéma de branchement d'un télérupteur pourvu d'un inverseur auxiliaire.

However, other particularities and advantages of the remote control switch according to the invention will appear during the following description. This is given with reference to the attached drawing for information only, and in which:
  • FIG. 1 represents the connection diagram of a remote control switch provided with an auxiliary inverter.

Comme indiqué ci-dessus, la figure 1 illustre le mode de branchement d'un télérupteur à inverseur auxiliaire. Ce télérupteur, qui est désigné par la référence générale 1, comprend une bobine 2 actionnant le support mobile 3 du ou des contacts principaux à commander.As indicated above, Figure 1 illustrates the connection mode of an auxiliary changeover switch. This remote control switch, which is designated by the general reference 1, comprises a coil 2 actuating the movable support 3 of the main contact or contacts to be controlled.

L'inverseu auxiliaire de ce télérupteur est inséré dans le circuit 4 d'alimentation de la bobine 2 et le support 5 de son contact mobile est lui-même actionné par cette bobine. Sur les deux contacts fixes 6 et 7 de cet inverseur auxiliaire sont branchés deux conducteurs de commande 8 et 9 comportant chacun un poussoir 10 ou 11 dont l'un correspond à la fonction "mise en marche" et l'autre à la fonction "arrêt".The auxiliary reverser of this remote control switch is inserted into the circuit 4 for supplying the coil 2 and the support 5 of its movable contact is itself actuated by this coil. On the two fixed contacts 6 and 7 of this auxiliary changeover are connected two control conductors 8 and 9 each comprising a pusher 10 or 11, one of which corresponds to the "start" function and the other to the "stop" function ".

Ainsi qu'il a déjà été indiqué, l'impulsion envoyée dans le conducteur 8, à partir du poussoir 10 de mise en marche, provoque la fermeture du ou des contacts principaux 3 du télérupteur ainsi que l'inversion du contact mobile 5 de l'inverseur auxiliaire, lequel vient se placer contre le second contact fixe 7 de celui-ci. Dans ces conditions, l'actionnement ultérieur du poussoir 11 sera en mesure d'assurer l'alimentation de la bobine 2 du télérupteur pour provoquer l'ouverture du ou des contacts principaux 3, ainsi qu'une nouvelle inversion du contact mobile 5 de l'inverseur auxiliaire.As already indicated, the pulse sent into the conductor 8, from the start push-button 10, causes the closing of the main contact or contacts 3 of the remote control switch as well as the reversal of the movable contact 5 of the 'auxiliary reverser, which is placed against the second fixed contact 7 thereof. Under these conditions, the subsequent actuation of the pusher 11 will be able to supply the coil 2 of the remote control switch to cause the opening of the main contact or contacts 3, as well as a new reversal of the movable contact 5 of the auxiliary reverser.

Comme représenté sur la figure 2, il est possible de connecter en parallèle la commande de plusieurs télérupteurs 1 de ce type. Ceci permet de commander le fonctionnement de l'ensemble de ceux-ci à partir de deux poussoirs communs 10 et 11. Cependant l'un ou l'autre des télérupteurs, ou chacun d'eux, peut également être commandé par un poussoir local 12 connecté directement à la bobine du télérupteur correspondant.As shown in FIG. 2, it is possible to connect the control of several remote control switches 1 of this type in parallel. This makes it possible to control the operation of all of these from two common push-buttons 10 and 11. However, either or both of the remote control switches can also be controlled by a local push-button 12 connected directly to the coil of the corresponding remote control switch.

Les figures 3 et 4 sont des vues schématiques illustrant le principe de fonctionnement de l'inverseur auxiliaire prévu dans le télérupteur selon l'invention. Sur ces figures les organes qui correspondent à ceux représentés sur les schémas des figures 1 et 2 sont indiqués par les mêmes chiffres de référence affectés de l'indice "a".Figures 3 and 4 are schematic views illustrating the operating principle of the auxiliary inverter provided in the remote control switch according to the invention. In these figures, the members which correspond to those represented in the diagrams of FIGS. 1 and 2 are indicated by the same reference numbers assigned to the index "a".

Dans l'exemple représenté, le support mobile des contacts principaux du télérupteur correspondant est constitué par un coulisseau 3a se déplaçant selon un axe Z-Zʹ. Les deux contacts fixes 6a et 7a de l'inverseur auxiliaire sont alors disposés en regard de ce coulisseau 3a sur une ligne MN parallèle à l'axe de déplacement de celui-ci, et de part et d'autre de l'axe de basculement A-­B des contacts principaux du télérupteur. Comme décrit par la suite, ce sont du reste les positions ainsi prévues pour ces deux contacts fixes qui déterminent les deux axes de basculement de l'inverseur auxilaire. Quant au support du contact mobile de cet inverseur, il consiste en un bras 5a monté pivotant en un point intermédiaire O de sa longueur, sur le coulisseau 3a.In the example shown, the mobile support of the main contacts of the corresponding remote control switch is constituted by a slide 3a moving along an axis Z-Zʹ. The two fixed contacts 6a and 7a of the auxiliary reverser are then arranged opposite this slide 3a on a line MN parallel to the axis of movement of the latter, and on either side of the tilting axis A-B of the main contacts of the remote control switch. As described below, these are the positions thus provided for these two fixed contacts which determine the two axes of tilting of the auxiliary reverser. As for the support of the movable contact of this reverser, it consists of an arm 5a pivotally mounted at an intermediate point O of its length, on the slide 3a.

Comme représenté sur les figures 5 et 6, ce bras pivotant peut consister en une palette métallique dont l'une des extrémités porte un double contact 13 constituant le contact mobile de l'inverseur auxiliaire. L'extrémité opposée 14 de cette palette est engagée à l'intérieur d'une cage 15 en matière isolante moulée. Cette cage comporte deux encoches 16 en forme de V à l'intérieur desquelles sont engagées deux épaulements 17 prévus sur les bords de la palette 5a. Ainsi, le fond des encoches 16 de la cage 15 matérialise l'axe O de pivotement de cette palette, laquelle peut se débattre à l'intérieur d'une ouverture 18 de la cage 15.As shown in Figures 5 and 6, this pivoting arm may consist of a metal pallet, one of the ends of which carries a double contact 13 constituting the movable contact of the auxiliary reverser. The opposite end 14 of this pallet is engaged at inside a cage 15 of molded insulating material. This cage has two V-shaped notches 16 inside which are engaged two shoulders 17 provided on the edges of the pallet 5a. Thus, the bottom of the notches 16 of the cage 15 materializes the pivot axis O of this pallet, which can be struggled inside an opening 18 of the cage 15.

L'extrémité 14 de la palette 5a se termine par une pointe 14a qui est engagée à l'intérieur de l'une des extrémités évasées 19 d'une pièce tubulaire 20 en forme de rivet creux. Cete pièce sert de support à un ressort de pression 21 qui prend appui dans le fond d'un siège 22 prévu dans la cage 15. L'extrémité opposée de ce ressort fait pression sur l'extrémité 14 de la palette 5a de façon à assurer la stabilité de celle-ci dans l'une et l'autre de ses deux positions extrêmes de fermeture des contacts correspondants.The end 14 of the pallet 5a ends in a point 14a which is engaged inside one of the flared ends 19 of a tubular piece 20 in the form of a hollow rivet. This piece serves as a support for a pressure spring 21 which bears on the bottom of a seat 22 provided in the cage 15. The opposite end of this spring presses on the end 14 of the pallet 5a so as to ensure the stability of the latter in both of its two extreme positions for closing the corresponding contacts.

L'ensemble ainsi constitué est placé à l'intérieur d'un logement 23 prévu dans le coulisseau 3a du télérupteur. Il faut noter que ce logement 23 peut recevoir indifféremment la cage 15 ou un jeu de contacts classique dans le cas où l'on voudrait réaliser un télérupteur ordinaire. La liaison électrique du contact mobile 13 avec la bobine de ce télérupteur est assurée par une tresse métallique 24 qui est soudée sur le guide tubulaire 20 portant le ressort 21.The assembly thus formed is placed inside a housing 23 provided in the slide 3a of the remote control switch. It should be noted that this housing 23 can indifferently receive the cage 15 or a set of conventional contacts in the case where it is desired to make an ordinary remote control switch. The electrical connection of the movable contact 13 with the coil of this remote control switch is ensured by a metal braid 24 which is welded to the tubular guide 20 carrying the spring 21.

Grâce à l'agencement prévu, la palette 5a s'articule à l'intérieur de l'extrémité correspondante du guide tubulaire 20 servant d'élément de support pour le ressort 21. Quant à l'extrémité opposée de ce ressort, elle peut s'articuler elle-même en quelque sorte dans le fond de son siège 22 par flexion élastique des spires de ce ressort. L'ensemble ainsi réalisé constitue un mécanisme élastique à genouillère dont la position instable de point mort est déterminée par l'alignement de la palette 5a sur la ligne transversal X-Y passant par l'axe O et le point central d'appui du ressort 21. Dans cette position celui-ci se trouve comprimé au maximum.Thanks to the arrangement provided, the pallet 5a is articulated inside the corresponding end of the tubular guide 20 serving as a support element for the spring 21. As for the opposite end of this spring, it can s 'articulate itself somehow in the bottom of its seat 22 by elastic bending of the turns of this spring. The assembly thus produced constitutes an elastic toggle mechanism whose unstable neutral position is determined by the alignment of the pallet 5a on the transverse line XY passing through the axis O and the central point of support of the spring 21. In this position the latter is compressed to the maximum.

Lorsque le coulisseau 3a du télérupteur se trouve dans l'une de ses positions extrêmes, par exemple celle représentée à la figure 3, la palette 5a est maintenue stable dans une position d'angulation par rapport à l'élément 20 portant le ressort 21. Ainsi le contact mobile 13 est alors maintenu contre le contact 6a. Cependant lorsque le coulisseau 3a se trouve dans sa position extrême opposée, la pliure du mécanisme à genouillère, constitué par la palette 5a et l'élément 20, est elle-même inverse de sorte que le contact mobile 13 est alors maintenu stable contre le contact fixe 7a.When the slide 3a of the remote control switch is in one of its extreme positions, for example that shown in FIG. 3, the pallet 5a is kept stable in an angulation position relative to the element 20 carrying the spring 21. Thus the movable contact 13 is then held against the contact 6a. However, when the slide 3a is in its opposite extreme position, the folding of the toggle mechanism, constituted by the pallet 5a and the element 20, is itself reversed so that the movable contact 13 is then kept stable against the contact fixed 7a.

Mais grâce à l'agencement prévu le mécanisme de l'inverseur auxiliaire possède deux axes distincts de basculement, respectivement C-D et E-F qui sont disposés de part et d'autre de l'axe de basculement A-B du mécanisme du télérupteur et sont suffisamment espacés l'un de l'autre. Chacun de ces axes de basculement est déterminé par l'alignement de la ligne transversale X-Y déjà définie, avec l'axe du contact mobile 13 dans sa position d'appui sur l'un ou l'autre des contacts fixes 6a et 7a. Or c'est l'existence de ces deux axes de basculement et leurs positions respectives qui permettent d'éviter que l'inverseur auxiliaire puisse rester dans une position d'ouverture lors du fonctionnement du télérupteur.However, thanks to the arrangement provided, the mechanism of the auxiliary reverser has two distinct tilting axes, CD and EF respectively, which are arranged on either side of the tilting axis AB of the remote control mechanism and are sufficiently spaced. of each other. Each of these tilting axes is determined by the alignment of the transverse line X-Y already defined, with the axis of the movable contact 13 in its support position on one or the other of the fixed contacts 6a and 7a. However, it is the existence of these two tilting axes and their respective positions which make it possible to prevent the auxiliary inverter from remaining in an open position during the operation of the remote control switch.

En effet, lorsqu'à partir de la position représentée à la figure 3 le coulisseau 3a est déplacé dans le sens de la flèche F1 et que la ligne transversale X-Y de l'inverseur vient en coïncidence avec l'axe de basculement A-B du mécanisme du télérupteur (position qui est représentée à la figure 4), ceci ne suffit pas pour provoquer le basculement de la palette 5a. Pour ce basculement il est nécessaire que le coulisseau 3a poursuive son mouvement jusqu'à ce que la ligne transversale X-Y de l'inverseur soit déplacée au-delà de l'axe de basculement C-D dont la position est définie par le point d'appui sur le contact fixe 6a.Indeed, when from the position shown in Figure 3 the slider 3a is moved in the direction of arrow F1 and the transverse line XY of the inverter comes into coincidence with the tilt axis AB of the mechanism of the remote control switch (position which is represented in FIG. 4), this is not sufficient to cause the tilting of the pallet 5a. For this tilting it is necessary for the slider 3a to continue its movement until the transverse line XY of the reverser is moved beyond the tilting axis CD, the position of which is defined by the fulcrum on the contact fixed 6a.

Ce n'est donc que bien après le franchissement de l'axe A-B du mécanisme du télérupteur que peut avoir lieu le basculement de l'inverseur auxiliaire. Dans ces conditions si, pour une des raisons exposées dans le préambule de la présente description, il se produit une immobilisation du mécanisme du télérupteur dans sa position de point mort, l'inverseur auxiliaire ne risque pas de se trouver alors lui-même en position d'ouverture, puisque sa palette 5a n'a pas encore été actionnée. En conséquence on est ainsi assuré que cet inverseur pourra transmettre ensuite à la bobine du télérupteur, l'impulsion suivante qui achèvera le basculement de celui-­ci.It is therefore only well after crossing the axis A-B of the remote control mechanism that the tilting of the auxiliary inverter can take place. Under these conditions if, for one of the reasons explained in the preamble to the present description, there is an immobilization of the mechanism of the remote control switch in its neutral position, the auxiliary reverser is not likely to then find itself in position opening, since its pallet 5a has not yet been actuated. Consequently, it is thus ensured that this inverter can then transmit to the coil of the remote control switch, the next pulse which will complete the tilting thereof.

Bien entendu, le même phénomène se produit lors du déplacement du coulisseau 3a en sens inverse. En effet, le basculement de l'inverseur ne pourra avoir lieu qu'après que la ligne transversale X-Y de l'inverseur ait largement dépassé l'axe de basculement A-B du mécanisme du télérupteur et ait atteint le second axe de basculement E-F de l'inverseur auxiliaire.Of course, the same phenomenon occurs during movement of the slider 3a in the opposite direction. Indeed, the reversing of the inverter can only take place after the transverse line XY of the reversing element has largely exceeded the tilting axis AB of the remote control mechanism and has reached the second tilting axis EF of the auxiliary inverter.

Les figures 7 et 8 représentent un exemple de réalisation pratique d'un télérupteur équipé d'un inverseur auxiliaire selon l'invention. Ce télérupteur, qui est du type de celui décrit dans le brevet français 2.309.032 de la société demanderesse, comporte un boitier 25 de forme plate renfermant à la fois le système magnétique de commande de celui-ci ainsi que le mécanisme associé. Il est donc prévu une bobine 26 actionnant une armature mobile 27. Celle-ci porte une bielle de poussée 28 dont l'extrémité opposée actionne un balancier 29. Ce dernier constitue l'organe de commande du coulisseau 3a portant les contacts principaux du télérupteur.Figures 7 and 8 show a practical embodiment of a remote control switch equipped with an auxiliary inverter according to the invention. This remote control switch, which is of the type described in French patent 2,309,032 of the applicant company, comprises a box 25 of flat shape enclosing both the magnetic control system thereof and the associated mechanism. There is therefore provided a coil 26 actuating a movable armature 27. The latter carries a thrust rod 28 whose opposite end actuates a pendulum 29. This the latter constitutes the control member of the slide 3a carrying the main contacts of the remote control switch.

Comme représenté sur la figure 7, ces contacts 29 sont montés, en leur milieu, à l'intérieur d'un logement 30 prévu sur l'une des faces de la partie inférieure du coulisseau 3a. Quant à l'inverseur auxiliaire précédemment décrit, il est porté par la face opposée de la partie inférieure du coulisseau 3a, laquelle face est représentée sur la figure 8. C'est donc sur cette face que le coulisseau 3a comporte un logement 23 à l'intérieur duquel est placée la cage 15 contenant les organes constitutifs de l'inverseur auxiliaire.As shown in FIG. 7, these contacts 29 are mounted, in their middle, inside a housing 30 provided on one of the faces of the lower part of the slide 3a. As for the previously described auxiliary inverter, it is carried by the opposite face of the lower part of the slider 3a, which face is shown in FIG. 8. It is therefore on this face that the slider 3a has a housing 23 at l 'inside which is placed the cage 15 containing the constituent elements of the auxiliary inverter.

Quant aux contacts fixes 6a et 7a de cet inverseur, ils sont prévus en regard de la partie correspondante du coulisseau 3a, comme déjà décrit précédemment.As for the fixed contacts 6a and 7a of this reverser, they are provided opposite the corresponding part of the slide 3a, as already described above.

Ainsi le montage de cet inverseur auxiliaire dans le présent télérupteur est extrêmement facile à réaliser et la présence de cet inverseur ne soulève aucune difficulté particulière pour la fabrication et le montage du présent télérupteur.Thus, the mounting of this auxiliary inverter in the present remote control switch is extremely easy to perform and the presence of this inverter does not raise any particular difficulty for the manufacture and the mounting of the present remote control switch.

Cependant il va de soi que le télérupteur représenté aux figures 7 et 8 ne constitue qu'un exemple de réalisation. En effect, pour sa partie correspondant à la fonction même de télérupteur, la conception de l'appareil et son agencement pourraient être différents, le mécanisme d'inverseur décrit précédemment pouvant être adapté à différents types de télérupteurs.However, it goes without saying that the remote control switch shown in Figures 7 and 8 is only one embodiment. In fact, for its part corresponding to the very function of remote control switch, the design of the device and its arrangement could be different, the reverser mechanism described above being able to be adapted to different types of remote control switches.
