Lors d'un assemblage du système de visualisation 3, d'abord le levier de manoeuvre 5 est, par sa moitié muni d'axe de pivotement 10, enfilé sur les bras porteurs 30, 31 du support 4 et tiré dans la direction de la gouttière 28 jusqu'à ce que cet axe de pivotement 10 dépasse celle-ci, avant de pousser ce levier 5 contre le support 4 à l'encontre de la lame élastique 14 de ce levier 5 et d'engager l'axe de pivotement 10 dans cette gouttière 28. La lame élastique 14 en s'appuyant sur le support 4 retient l'axe de pivotement 10 du levier 5 dans cette gouttière 28. Le levier 5 qui est guidé latéralement par les bras porteurs 30, 31, peut alor pivoter dans cette gouttière 28 autour de son axe 10, entre deux limites au niveau de sa came 16, l'une constituée par la butée 32 du support 4 et l'autre définie par les extrémités libres de ces bras porteurs 30, 31.During assembly of the display system 3, first the operating lever 5 is, by its half provided with pivot axis 10, threaded on the support arms 30, 31 of the support 4 and pulled in the direction of the gutter 28 until this pivot axis 10 exceeds the latter, before pushing this lever 5 against the support 4 against the elastic blade 14 of this lever 5 and engaging the pivot axis 10 in this gutter 28. The elastic blade 14 by pressing on the support 4 retains the pivot axis 10 of the lever 5 in this gutter 28. The lever 5 which is guided laterally by the carrying arms 30, 31, can then pivot in this gutter 28 around its axis 10, between two limits at the level of its cam 16, one formed by the stop 32 of the support 4 and the other defined by the free ends of these carrying arms 30, 31.

Deux nervures 39, 40 sont formées dans la zone centrale des faces internes de ses bras latéraux 8, 9 pour faciliter le glissement de ces bras 8, 9 sur les bras porteurs 30, 31 du support 4 et le pivotement de ce levier 5.Two ribs 39, 40 are formed in the central zone of the internal faces of its lateral arms 8, 9 to facilitate the sliding of these arms 8, 9 on the support arms 30, 31 of the support 4 and the pivoting of this lever 5.

Ensuite l'élément signalétique 6 est monté à travers la fenêtre d'exposition 34 et l'espace libre 42 situé entre les bras latéraux 8, 9 du levier 5, dans les bras-porteurs 30, 31 de manière à engager par élasticité de ses tiges 22, 23, ses ergots alignés 24, 25 dans les trous 36, 37 des bras porteurs 30, 31 et à appliquer le creux de son profil en V contre la came 16 du levier 5.Then the descriptive element 6 is mounted through the exposure window 34 and the free space 42 situated between the lateral arms 8, 9 of the lever 5, in the support arms 30, 31 so as to engage by elasticity of its rods 22, 23, its lugs aligned 24, 25 in the holes 36, 37 of the support arms 30, 31 and to apply the hollow of its V profile against the cam 16 of the lever 5.

Le levier 5, l'élément signalétique 6 et le support 4 sont ainsi autobloqués par leur interliaison mécanique. Le levier 5 encadrant les bras porteurs 30, 31 du support 4 et bloqué d'un côté par l'élément signalétique 6 du côté opposé par la gouttière 28 du support 4, ne peut être déplacé ni latéralement, ni longitudina­lement, et peut seulement pivoter autour de son axe 10 entre une première butée constituée par l'entretoise 32 du support 4 et une deuxième butée constituée par les extrémités libres des bras porteurs 30, 31 de ce support 4.The lever 5, the descriptive element 6 and the support 4 are thus self-locked by their mechanical connection. The lever 5 framing the support arms 30, 31 of the support 4 and blocked on one side by the descriptive element 6 on the opposite side by the gutter 28 of the support 4, cannot be moved either laterally or longitudinally, and can only pivot around its axis 10 between a first stop constituted by the spacer 32 of the support 4 and a second stop constituted by the free ends of the support arms 30, 31 of this support 4.

Lors d'un démontage du système de visualisation 3, d'abord l'élément signalétique 6 est enlevé des trous 36, 37 des bras porteurs 30, 31 en pinçant ses tiges élastiques 22, 23 pour dégager ses ergots alignés 24, 25, ensuite le levier de manoeuvre 5 est déplacé longitudinalement pour sortir son axe 10 de la gouttière 28 avant d'être repoussé longitudinalement en sens inverse pour être dégagé des extrémités libres des bras porteurs 30, 31 du support 4.During disassembly of the display system 3, first of all the descriptive element 6 is removed from the holes 36, 37 of the support arms 30, 31 by pinching its elastic rods 22, 23 to release its aligned lugs 24, 25, then the operating lever 5 is moved longitudinally to extend its axis 10 from the gutter 28 before being pushed longitudinally in the opposite direction to be released from the free ends of the support arms 30, 31 of the support 4.

Dans l'exemple illustré aux figures 3, 4, 5, la saillie 11 du levier de manoeuvre 5 est coiffée d'un capuchon-enjoliveur 42 et le support 4 est recouvert d'une plaque transparente 43 revêtue dans sa face interne d'une couche de peinture opaque 44 qui ne laisse qu'une fenêtre transparente 45 juste au-dessus de la fenêtre d'exposition 34 du support 4. Cette fenêtre transparente 45 permet d'observer une présence ou une absence de la barrette colorée 26 de l'élément signalétique pivotante 6 et simultanément une absence ou une présence d'une partie exposée du levier de manoeuvre 5 celle au niveau de la came 16 de ce levier se trouvant juste au-dessous de cette fenêtre transparente 45, étant donné que cette partie exposée du levier 5 est cachée ou laissée découverte par cet élément signalétique 6. La couleur portée par cette partie du levier 5 est choisie comme une deuxième couleur de signalisation.In the example illustrated in Figures 3, 4, 5, the projection 11 of the operating lever 5 is capped with a cap-cover 42 and the support 4 is covered with a transparent plate 43 coated in its internal face with a opaque paint layer 44 which leaves only a transparent window 45 just above the exposure window 34 of the support 4. This transparent window 45 makes it possible to observe a presence or an absence of the colored bar 26 of the element pivoting signage 6 and simultaneously an absence or presence of an exposed part of the operating lever 5 that at the level of the cam 16 of this lever being located just below this transparent window 45, since this exposed part of the lever 5 is hidden or left uncovered by this descriptive element 6. The color worn by this part of the lever 5 is chosen as a second signaling color.

L'élément signalétique 6 peut être soit constitué par une matière qui a une couleur choisie comme première couleur de signalisation, cette couleur étant différente de la couleur de la partie exposée du levier 5 qui se trouve juste en dessous de la fenêtre d'exposition 34 du support 4 et de la fenêtre transparente 45 de la plaque 43, soit pourvu d'une barrette transversale 26 revêtue sur sa surface extérieure d'une couche de peinture ayant une couleur choisie comme première couleur de signalisation, cette couleur étant différente de celle de la partie exposée du levier 5.The descriptive element 6 can either be constituted by a material which has a color chosen as the first signal color, this color being different from the color of the exposed part of the lever 5 which is located just below the exposure window 34 of the support 4 and of the transparent window 45 of the plate 43, or provided with a transverse bar 26 coated on its outer surface with a layer of paint having a color chosen as the first signaling color, this color being different from that of the exposed part of the lever 5.

La partie exposée du levier de manoeuvre 5 visible à travers la fenêtre d'exposition 34 et la fenêtre transparente 45 peut avoir une couleur choisie comme deuxième couleur de signalisation identique à celle de ce levier de manoeuvre ou peut être revêtue d'une couche de peinture ayant une couleur choisie comme deuxième couleur de signalisation mais différente de la couleur de ce levier de manoeuvre 5.The exposed part of the operating lever 5 visible through the exposure window 34 and the transparent window 45 may have a color chosen as the second signaling color identical to that of this operating lever or may be coated with a layer of paint. having a color chosen as the second signaling color but different from the color of this operating lever 5.

Dans l'exemple illustré dans les figures 3 et 4, la saillie 11 du levier de manoeuvre 5 est pourvue dans sa face interne, d'une protubérance 46 destinée à être en contact d'appui sur l'extrémité libre de l'axe de commande 2 du commutateur électrique associé 1 du type à bouton poussoir à retenue en enclenchement.In the example illustrated in FIGS. 3 and 4, the projection 11 of the operating lever 5 is provided in its internal face with a protuberance 46 intended to be in bearing contact on the free end of the axis of control 2 of the associated electrical switch 1 of the push-button type with locking engagement.

En position de repos, le levier de manoeuvre 5 est élasti­quement poussé par l'axe de commande 2 du commutateur 1 contre la butée 32 du support 4 (figure 3) et la barrette colorée 26 de l'élément signalétique 6 est escamotée et n'est pas visible à travers la fenêtre transparente 45.In the rest position, the operating lever 5 is elastically pushed by the control axis 2 of the switch 1 against the stop 32 of the support 4 (FIG. 3) and the colored bar 26 of the descriptive element 6 is retracted and does not is not visible through the transparent window 45.

Lors d'un enclenchement du commutateur 1, le levier 5 est pivoté, par une poussée appliquée sur le capuchon 42 coiffant la saillie 11, pour enfoncer l'axe 2 dans le commutateur 1 jusqu'à sa position d'enclenchement où l'axe 2 y est retenu. Durant le pivo­tement du levier de manoeuvre 5, la première surface active 17 de sa came 16 pousse les extrémités libres des tiges 22, 23 de l'élément signalétique pivotante 6 et fait pivoter celui-ci autour de ses ergots 24, 25 pour faire apparaître en fin de course d'enclenchement du commutateur 1, la barrette colorée 26 sous la fenêtre transparente 45 tandis que la deuxième surface active 18 de sa came 16 sert d'appui à cette barrette colorée 26 dans son glissement au cours de ce pivotement de l'élément signalétique 6 (figure 4). La couleur de la barrette colorée 26 apparue sous la fenêtre transparente 45 indique alors la position d'enclenchement du levier 5.When switch 1 is engaged, lever 5 is pivoted, by a thrust applied to the cap 42 covering the projection 11, to push the axis 2 into the switch 1 to its engagement position where the axis 2 is retained there. During the pivoting of the operating lever 5, the first active surface 17 of its cam 16 pushes the free ends of the rods 22, 23 of the pivoting descriptive element 6 and makes it pivot around its lugs 24, 25 to reveal at the end of the switch 1 switching stroke, the colored bar 26 under the transparent window 45 while the second active surface 18 of its cam 16 serves as a support for this colored bar 26 in its sliding during this pivoting of the 'sign 6 (Figure 4). The color of the colored bar 26 which appears under the transparent window 45 then indicates the position in which the lever 5 is engaged.

Lors d'un déclenchement du commutateur 1, le levier 5 est pivoté par une poussée appliquée sur le capuchon 42 pour enfoncer l'axe 2 dans le commutateur 1 jusqu'à sa position de déclenchement où l'axe 2 est libéré et rappelé dans sa position de repos (figure 3) par un système connu à ressort non représenté. Durant le pivo­tement du levier de manoeuvre 5, la deuxième surface active 18 de la came 16 glisse sur la face interne de la barrette colorée 26 et fait pivoter l'élément signalétique 6 jusqu'à une position d'escamotage où cette barrette colorée 26 n'est plus visible de la fenêtre transpa­rente 45 (figure 3) tandis que la première surface active 17 de la came 16 sert d'appui aux tiges 22, 23 dans leur glissement au cours du pivotement de l'élément signalétique 6.When a switch 1 is triggered, the lever 5 is pivoted by a thrust applied to the cap 42 to push the axis 2 into the switch 1 to its trigger position where the axis 2 is released and returned to its rest position (Figure 3) by a known spring system not shown. During the pivoting of the operating lever 5, the second active surface 18 of the cam 16 slides on the internal face of the colored bar 26 and rotates the descriptive element 6 to a retracting position where this colored bar 26 n 'is more visible from the transparent window 45 (FIG. 3) while the first active surface 17 of the cam 16 serves to support the rods 22, 23 in their sliding during the pivoting of the descriptive element 6.

Pendant ce temps la partie exposée du levier 5, celle située au niveau de sa came 16, qui a une couleur différente de celle de cette barrette colorée 26 de l'élément signalétique 6, apparaît sous la fenêtre transparente 45. La couleur de cette partie exposée du levier 5 apparue visible sous la fenêtre transparente 45, qui est une deuxième couleur de signalisation, indique alors la position de repos de ce levier 5.During this time, the exposed part of the lever 5, that situated at the level of its cam 16, which has a color different from that of this colored bar 26 of the descriptive element 6, appears under the transparent window 45. The color of this part exposed of the lever 5 appeared visible under the transparent window 45, which is a second signaling color, then indicates the rest position of this lever 5.

Dans cet exemple deux couleurs assurent ainsi la visualisation de deux positions respectives de fonctionnement du commutateur électrique associé 1 : la couleur de la barrette colorée 26 apparue sous la fenêtre transparente 45 indique la position d'enclenchement de ce commutateur 1 par le levier 5, et la couleur de la partie exposée de ce dernier levier, visible sous la fenêtre transparente 45 indique la position de déclenchement de ce commutateur 1 par ce même levier 5.In this example two colors thus ensure the visualization of two respective operating positions of the switch associated electric 1: the color of the colored bar 26 appeared under the transparent window 45 indicates the position of engagement of this switch 1 by the lever 5, and the color of the exposed part of this last lever, visible under the transparent window 45 indicates the trigger position of this switch 1 by this same lever 5.

Dans l'exemple illustré à la figure 5, le système de visuali­sation 3 comprend un support 4, trois leviers de manoeuvre iden­tiques 5, leurs capuchon-enjoliveurs 42 étant seuls visibles, et trois éléments signalétiques identiques 6, deux de ces éléments signalé­tiques 6 étant visibles par leurs barrettes colorées 26 à travers la fenêtre transparente commune 45 et le troisième élément signalé­tique 6 en position escamoté étant invisible à travers cette fenêtre transparente 45.In the example illustrated in FIG. 5, the display system 3 comprises a support 4, three identical operating levers 5, their cap-covers 42 being visible alone, and three identical descriptive elements 6, two of these descriptive elements 6 being visible by their colored bars 26 through the common transparent window 45 and the third descriptive element 6 in the retracted position being invisible through this transparent window 45.

Quand les barrettes colorées 26 sont visibles à travers la fenêtre transparente 45, les commutateurs 1 associés aux leviers de manoeuvre 5 sont enclenchées. Lorsque l'une ou plusieurs barrettes colorées 26 sont invisibles à travers la fenêtre apparente 45, le ou les commutateurs 1 associés aux leviers de manoeuvre ayant cette ou ces barrettes colorées 26, sont déclenchés. Il en résulte que le système 3 visualise fidèlement les positions d'enclenchement et de déclenchement des commutateurs associés.When the colored bars 26 are visible through the transparent window 45, the switches 1 associated with the operating levers 5 are activated. When one or more colored bars 26 are invisible through the visible window 45, the switch or switches 1 associated with the operating levers having this or these colored bars 26, are triggered. As a result, the system 3 faithfully displays the switch-on and switch-off positions of the associated switches.

Dans une variante de réalisation de l'invention illustrée dans les figures 6 et 7, le système de visualisation 50 de positions de fonctionnement de un ou plusieurs commutateurs électriques associés du type à bouton poussoir à retenue en enclenchement comprend un support 51, un levier de manoeuvre 52 et un élément signalétique 53.In an alternative embodiment of the invention illustrated in FIGS. 6 and 7, the display system 50 for operating positions of one or more associated electrical switches of the push-button type with locking engagement comprises a support 51, a lever operation 52 and a descriptive element 53.

Le levier de manoeuvre 52 est une pièce pivotante comprenant deux bras latéraux parallèles espacés 54, 55 reliés par des entre­toises 56 et portant à l'une de leurs extrémités des tourillons alignés 57, 58 servant d'axe de pivotement, à l'autre de leurs extrémités une saillie 60 servant de touche et dans sa zone centrale deux ergots alignés 62, 63 en saillie latéralement vers l'extérieur destinés à commander l'élément signalétique 53.The operating lever 52 is a pivoting part comprising two spaced parallel lateral arms 54, 55 connected by spacers 56 and carrying at one of their ends aligned trunnions 57, 58 serving as a pivot axis, at the other of their ends a projection 60 serving as a key and in its central zone two aligned pins 62, 63 projecting laterally outwards intended for order the descriptive element 53.

L'élément signalétique 53 est une pièce coulissante ayant une section transversale en U inversé comportant d'une part dans ses deux parois latérales deux fentes inclinées parallèles ouvertes vers l'extérieur 66, 67 destinées à recevoir les deux ergots alignés 62, 63 du levier de manoeuvre 52 et deux nervures latérales de coulis­sement 68, 69 formées au niveau du fond du U en saillie vers l'extérieur et d'autre part, sur une moitié transversale 70 de la surface extérieure du fond du U inversé et dans l'alignement des fentes inclinées 66, 67, une couleur choisie de signalisation.The descriptive element 53 is a sliding part having an inverted U cross section comprising on the one hand in its two side walls two parallel inclined slots open towards the outside 66, 67 intended to receive the two aligned pins 62, 63 of the lever operating 52 and two lateral sliding ribs 68, 69 formed at the bottom of the U projecting outwards and on the other hand, on a transverse half 70 of the outer surface of the bottom of the inverted U and in alignment inclined slots 66, 67, a selected signal color.

Selon une autre variante de réalisation, dans l'élément signalé­tique 53, une moitié transversale 70 de la surface extérieure du fond du U inversé et dans l'alignement des fentes inclinées 66, 67, porte une première couleur choisie de signalisation et l'autre moitié transversale restante de cette surface extérieure du fond du U inversé porte une deuxième couleur choisie de signalisation.According to another alternative embodiment, in the descriptive element 53, a transverse half 70 of the outer surface of the bottom of the inverted U and in alignment with the inclined slots 66, 67, carries a first chosen signaling color and the other remaining transverse half of this outer surface of the bottom of the inverted U carries a second chosen signal color.

Le support 51 comprend un cadre 71 de préférence sensi­blement rectangulaire, muni à l'une des extrémités, d'une ouverture 72 de réception de la saillie 60 servant de touche du levier de manoeuvre 52, à l'autre extrémité, dans ses parois latérales, de deux trous 73, 74 de réception des tourillons alignés 57, 58, et dans la zone centrale, d'une fenêtre d'exposition 76 et deux rampes de glissement parallèles 78, 79 et d'une butée d'arrêt 80, disposées en dessous de cette fenêtre 76. Les rampes 78, 79 sont destinées à recevoir les nervures latérales de coulissement 68, 69 de l'élément signalétique 53.The support 51 comprises a frame 71 preferably substantially rectangular, provided at one end with an opening 72 for receiving the projection 60 serving as a button for the operating lever 52, at the other end, in its side walls , two holes 73, 74 for receiving the aligned pins 57, 58, and in the central area, an exposure window 76 and two parallel sliding ramps 78, 79 and a stopper 80, arranged below this window 76. The ramps 78, 79 are intended to receive the lateral sliding ribs 68, 69 of the descriptive element 53.

Le support 51 peut être recouvert d'une plaque transparente 82 et la saillie 60 du levier de manoeuvre 52 peut être pourvue d'un capuchon enjoliveur 83.The support 51 can be covered with a transparent plate 82 and the projection 60 of the operating lever 52 can be provided with an embellished cap 83.

Dans un assemblage du système de visualisation 50, d'abord l'élément signalétique 53 est monté et coulissé, dans les rampes de glissement 78, 79 du support 51 jusqu'à la butée 80 et ensuite le levier 52 est monté dans le support 51 en engageant sa saillie 60 dans l'ouverture 72 du support 51 et ses ergots alignés 62, 63 dans les fentes inclinées de l'élément signalétique 53 avant de pincer élastiquement les extrémités des bras latéraux 54, 55 pour engager les tourillons alignés 57, 58 dans les trous 73, 74 du support 51. Le levier de manoeuvre 52 engagé dans les trous de pivotement 73, 74 du support 51 et les fentes inclinées de l'élément signalétique 53 peut alors pivoter autour de ses tourillons 57, 58.In an assembly of the display system 50, first of all the descriptive element 53 is mounted and slid, in the sliding ramps 78, 79 from the support 51 to the stop 80 and then the lever 52 is mounted in the support 51 by engaging its projection 60 in the opening 72 of the support 51 and its aligned pins 62, 63 in the inclined slots of the descriptive element 53 before elastically pinching the ends of the lateral arms 54, 55 to engage the aligned pins 57, 58 in the holes 73, 74 of the support 51. The operating lever 52 engaged in the pivot holes 73, 74 of the support 51 and the inclined slots of the descriptive element 53 can then pivot around its pins 57, 58.

Lors d'un enclechement du commutateur 1 associé au système de visualisation 50, le levier 52 est pivoté par une poussée appliquée sur le capuchon 83 pour enfoncer l'axe 2 dans le commutateur 1 jusqu'à sa position d'enclenchement (figure 7) où l'axe 2 y est retenu. Durant ce pivotement du levier 52, ses ergots alignés 62, 63 poussent les parois inclinées des fentes 66, 67 et font coulisser l'élément signalétique 53 sur les rampes de glissement 78, 79 de manière à faire apparaître en fin de course d'enclenchement du commutateur associé 1, la couleur de signalisation de sa partie 70, sous la fenêtre d'exposition 76 du support 51. L'apparition de la couleur de signalisation de cette partie 70 indique la position d'enclenchement du commutateur 1 par le levier 52.When the switch 1 associated with the display system 50 is engaged, the lever 52 is pivoted by a push applied to the cap 83 to push the axis 2 into the switch 1 until it is in the engaged position (FIG. 7) where axis 2 is retained there. During this pivoting of the lever 52, its aligned pins 62, 63 push the inclined walls of the slots 66, 67 and cause the descriptive element 53 to slide on the sliding ramps 78, 79 so as to make appear at the end of the engaging stroke of the associated switch 1, the signaling color of its part 70, under the exposure window 76 of the support 51. The appearance of the signaling color of this part 70 indicates the engagement position of the switch 1 by the lever 52 .

Lors d'un déclenchement du commutateur 1, le levier 52 est pivoté par une poussée appliquée sur le capuchon 83 pour enfoncer l'axe 2 dans le commutateur 1 jusqu'à sa position de déclenchement où l'axe 2 est libéré et rappelé dans sa position de repos (figure 6) par un système connu à ressort non représenté. Durant ce pivo­tement du levier 52, ses ergots alignés 62, 63 poussent les parois inclinées des fentes 66, 67 et font coulisser en sens inverse l'élément signalétique 53 sur les rampes de glissement 78, 79 de manière à faire disparaître de la fenêtre d'exposition 76, la couleur de signalé­sation de la partie 70 de cet élément signalétique 53. L'absence de la couleur de signalisation de cette partie 70 indique la position de déclenchement du commutateur 1 par le levier 52.When a switch 1 is triggered, the lever 52 is pivoted by a thrust applied to the cap 83 to push the axis 2 into the switch 1 to its trigger position where the axis 2 is released and returned to its rest position (Figure 6) by a known spring system not shown. During this pivoting of the lever 52, its aligned lugs 62, 63 push the inclined walls of the slots 66, 67 and cause the descriptive element 53 to slide in the opposite direction on the sliding ramps 78, 79 so as to make the window d exposure 76, the signaling color of the part 70 of this descriptive element 53. The absence of the signaling color of this part 70 indicates the triggering position of the switch 1 by the lever 52.

Dans le cas où l'élément signalétique 53 porte deux couleurs de signalisation, durant le pivotement du levier 52 lors d'un déclen­chement du commutateur associé 1, les ergots alignés 62, 63 de ce levier poussent les parois inclinées des fentes 66, 67 et font coulisser l'élément signalétique 53 sur les rampes de glissement 78, 79 de manière à faire disparaître de la fenêtre d'exposition 76, la première couleur de signalisation portée par la partie 70 c'est-à-dire l'une des moitiés transversales de l'élément signalétique 53, et simultanément à faire apparaître à cette fenêtre d'exposition 76, la deuxième couleur de signalisation portée par l'autre moitié transver­sale de cet élément signalétique 53. Dans cet élément signalétique à deux couleurs de signalisation, la présence de la première couleur de signalisation à la fenêtre d'exposition 76 indique la position d'enclen­chement du commutateur associé 1 et l'apparition de la deuxième couleur de signalisation à cette fenêtre d'exposition 76 indique la position de déclenchement de ce commutateur associé 1.In the case where the descriptive element 53 carries two signal colors, during the pivoting of the lever 52 when the associated switch 1 is triggered, the aligned pins 62, 63 of this lever push the inclined walls of the slots 66, 67 and do slide the identifying element 53 on the sliding ramps 78, 79 so as to make the first signaling color carried by the part 70, that is to say one of the transverse halves, disappear from the exposure window 76 of the signage element 53, and simultaneously showing this display window 76, the second signaling color carried by the other transverse half of this signage element 53. In this signage element with two signaling colors, the presence of the first signaling color at the exposure window 76 indicates the engagement position of the associated switch 1 and the appearance of the second signaling color at this exposure window 76 indicates the triggering position of this associated switch 1 .

Comme le système de l'exemple des figures 3 à 5, le système 50 visualise fidèlement les positions d'enclenchement et déclen­chement des commutateurs associés 1.Like the system of the example in FIGS. 3 to 5, the system 50 faithfully displays the switch-on and switch-off positions of the associated switches 1.

Les supports 4, levier 5 et élément signalétique 6 du système de visualisation 3 comme les support 51, levier 52 et élément signalétique 53 du système de visualisation 50 sont maintenus assemblés par leur interliaison mécanique. Ils sont d'une part faciles à fabriquer et à assembler par conséquent économiques et d'autre part solides, efficaces et fidèles dans leur fonctionnement.The supports 4, lever 5 and descriptive element 6 of the display system 3 such as the support 51, lever 52 and descriptive element 53 of the display system 50 are held together by their mechanical connection. They are on the one hand easy to manufacture and assemble therefore economical and on the other hand solid, efficient and faithful in their operation.
