Abstract

A modular auxiliary switch (100) comprises a mechanism (18) for controlling at least one interruptor (16) with inverting contacts (32, 34, 36), and a manual test device (70) intended to check the operation of the elements inserted into the auxiliary electrical circuit, without change of state of the associated circuit breaker block. The test device (70) comprises a test button (76) and a control lever (72) acting directly on the moving contact (32) when the test button (76) is depressed, in order to cause the forced switching of the interruptor (16), independently of the mechanism (18) which remains stationary. After the test button (76) has been released, the lever (72) returns automatically to an inactive position thanks to the return action of a spring (78). This device avoids the local resetting of the mechanism (18) after the test. <IMAGE>

- un mécanisme de commande à manette et à ressort accumulateur,
- un premier et/ou un deuxième interrupteur coopérant avec ledit mécanisme pour reflèter la position ouvert ou fermé des contacts principaux du bloc disjoncteur, et/ou pour signaler l'ouverture sur défaut par déclenchement automatique du bloc disjoncteur, chaque interrupteur étant du type inverseur comprenant une paire de contacts fixes et un contact mobile coopérant alternativement avec l'un desdits contacts fixes,
- un premier et/ou un deuxième jeu de bornes de raccordement à au moins un circuit électrique extérieur de commande et de signalisation,
- et un dispositif de test manuel à bouton test susceptible d'être actionné pour vérifier le fonctionnement des organes insérés dans ledit circuit extérieur, sans changement d'état du bloc disjoncteur.The invention relates to a modular auxiliary switch with an insulating housing capable of being coupled and coupled to a circuit breaker block, said switch comprising:
- a lever and accumulator spring control mechanism,
- a first and / or a second switch cooperating with said mechanism to reflect the open or closed position of the main contacts of the circuit breaker block, and / or to signal the opening on fault by automatic tripping of the circuit breaker block, each switch being of the reversing type comprising a pair of fixed contacts and a movable contact cooperating alternately with one of said fixed contacts,
- a first and / or a second set of terminals for connection to at least one external electrical control and signaling circuit,
- And a manual test device with test button capable of being actuated to check the operation of the members inserted in said external circuit, without change of state of the circuit breaker block.

Dans un commutateur combiné SD/OF connu décrit dans le document EP-A 303965, le bouton test coopère avec le mécanisme de commande du commutateur pour assurer la fonction test associée à un circuit extérieur auxiliaire. L'état du bloc disjoncteur n'a pas été affecté par le test, mais un réarmement local du mécanisme de commande de commutateur s'avère indispensable après le test.In a known SD / OF combination switch described in document EP-A 303965, the test button cooperates with the switch control mechanism to perform the test function associated with an auxiliary external circuit. The status of the circuit breaker block was not affected by the test, but a local reset of the switch control mechanism is essential after the test.

Dans le commutateur décrit dans le modèle d'utilité allemand no 8.802.393, le dispositif de test comporte un bouton poussoir qui agit sur un levier de transmission coopérant avec un coulisseau de support des contacts mobiles. Un premier ressort de rappel est associé au coulisseau, et un deuxième ressort de rappel est affecté au bouton poussoir.In the switch described in German Utility Model No. 8,802,393, the test device comprises a push button which acts on a transmission lever cooperating with a slide support for mobile contacts. A first return spring is associated with the slide, and a second return spring is assigned to the push button.

L'objet de l'invention consiste à simplifier la réalisation de la fonction test d'un commutateur auxiliaire pour disjoncteur modulaire.The object of the invention is to simplify the implementation of the test function of an auxiliary switch for a modular circuit breaker.

Le commutateur selon l'invention est caractérisé en ce que le dispositif de test comporte un levier d'actionnement agissant directement sur au moins un des contacts mobiles pour provoquer la commutation forcée de l'interrupteur correspondant, indépendamment du mécanisme de commande qui reste immobile, et que ledit levier est monté à pivotement sur un axe entre une position active de test, et une position inactive, le bouton test étant agencé à l'une des extrémités dudit levier, alors que l'autre extrémité entraîne le contact mobile vers le contact fixe opposé lors de l'opération de test.The switch according to the invention is characterized in that the test device comprises an actuating lever acting directly on at least one of the movable contacts to cause the forced switching of the corresponding switch, independently of the control mechanism which remains stationary, and that said lever is pivotally mounted on an axis between an active test position and an inactive position, the test button being arranged at one end of said lever, while the other end drives the movable contact towards the contact fixed opposite during the test operation.

Après relâchement du bouton test, le retour du levier test vers la position inactive s'effectue automatiquement par un seul ressort de rappel. Le mécanisme de commande du commutateur reste immobile durant le test, ce qui évite tout réarmement postérieur.After releasing the test button, the return of the test lever to the inactive position is effected automatically by a single return spring. The control mechanism of the switch remains stationary during the test, which avoids any subsequent reset.

La fonction test selon l'invention peut être mise en oeuvre dans quatre types de commutateurs auxiliaires, notamment un commutateur combiné SD/OF, un commutateur simple SD, un commutateur simple OF, et un commutateur double OF/OF.The test function according to the invention can be implemented in four types of auxiliary switches, in particular a combined SD / OF switch, a single SD switch, a single OF switch, and a double OF / OF switch.

Dans le cas d'un test SD associé au deuxième interrupteur, le bouton test du levier de commande est situé en un endroit prédéterminé du boîtier, rendu inaccessible après mise en place d'un plastron.In the case of an SD test associated with the second switch, the test button on the control lever is located at a predetermined location on the housing, made inaccessible after fitting a faceplate.

Le test est alors accessible à l'installateur, mais pas au client.The test is then accessible to the installer, but not to the customer.

L'axe de pivotement dudit levier se trouve au voisinage d'une rampe interne de la manette, l'enfoncement du bouton test provoquant le déplacement forcé du contact mobile vers le contact fixe opposé du deuxième interrupteur, de manière à simuler dans ledit circuit extérieur un déclenchement du bloc disjoncteur, sans interruption du circuit principal.The pivot axis of said lever is in the vicinity of an internal ramp of the lever, the depression of the test button causing the forced displacement of the movable contact towards the opposite fixed contact of the second switch, so as to simulate in said external circuit tripping of the circuit breaker block, without interrupting the main circuit.

Dans le cas d'un test OF, le bouton test du levier support appartenant au dispositif de test est agencé du côté de la manette sur la face avant du boîtier. Le levier support est doté d'une patte située à l'opposé du bouton test pour entraîner le contact mobile vers le contact fixe du premier interrupteur, de manière à simuler une fermeture dans le circuit extérieur correspondant, alors que le bloc disjoncteur reste ouvert durant ce test OF.In the case of an OF test, the test button of the support lever belonging to the test device is arranged on the side of the handle on the front face of the housing. The support lever has a tab located opposite the test button to drive the movable contact to the fixed contact of the first switch, so as to simulate a closure in the corresponding external circuit, while the circuit breaker block remains open during this OF test.

Dans le cas d'un test double OF/OF, le levier support agit simultanément sur les deux contacts mobiles des interrupteurs, pour assurer un double test de fermeture sur deux circuits auxiliaires indépendants, alors que le bloc disjoncteur reste ouvert.In the case of a double OF / OF test, the support lever acts simultaneously on the two movable contacts of the switches, to ensure a double closing test on two independent auxiliary circuits, while the circuit breaker block remains open.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre de différents modes de réalisations de l'invention, donnés à titre d'exemples non limitatifs, et représentés aux dessins annexés, dans lesquels:

  • - la figure 1 montre une vue schématique en élévation d'un commutateur combiné SD/OF, équipé du dispositif de test selon l'invention représenté en position inactive, la manette du mécanisme étant en position de fermeture;

  • - la figure 3 est une vue identique de la figure 1 d'un commutateur simple OF;
  • - la figure 4 est une vue identique de la figure 1 d'un commutateur double OF/OF.
Other advantages and characteristics will emerge more clearly from the description which follows of different embodiments of the invention, given by way of nonlimiting examples, and represented in the appended drawings, in which:
  • - Figure 1 shows a schematic elevation view of a combined SD / OF switch, equipped with the test device according to the invention shown in the inactive position, the handle of the mechanism being in the closed position;

Sur la figure 1, un commutateur 10 double SD/OF de commande et de signalisation est conformé en module auxiliaire, susceptible d'être accolé et accouplé à un bloc disjoncteur (non représenté).In FIG. 1, a double SD / OF control and signaling switch 10 is configured as an auxiliary module, capable of being coupled and coupled to a circuit breaker block (not shown).

Le commutateur 10 est logé dans un boîtier 12 isolant, et est composé d'un interrupteur auxiliaire 14 pour la fonction OF et d'un interrupteur de signalisation 16 pour la fonction SD actionné par un mécanisme de commande 18 à manette 19, décrit en détail dans la demande de brevet français no8801151.The switch 10 is housed in an insulating box 12, and is composed of an auxiliary switch 14 for the OF function and a signaling switch 16 for the SD function actuated by a control mechanism 18 with lever 19, described in detail in the french patent application No. 8,801,151.

Le premier interrupteur auxiliaire 14 est équipé d'un système de contacts inverseurs 20,22,24, destiné à refléter la position ouvert ou fermé des contacts principaux du bloc disjoncteur (fonction OF). Le système de contacts comporte un contact mobile 24 en forme d'épingle coopérant alternativement avec deux contacts fixes 20,22, l'ensemble étant en liaison électrique avec un premier jeu de bornes 26,28,30 de raccordement situées sur l'une des faces latérales étroites du boîtier 12.The first auxiliary switch 14 is equipped with a reversing contact system 20,22,24, intended to reflect the open or closed position of the main contacts of the circuit breaker block (OF function). The contact system comprises a movable contact 24 in the form of a pin cooperating alternately with two fixed contacts 20, 22, the assembly being in electrical connection with a first set of connection terminals 26, 28, 30 located on one of the narrow side faces of the housing 12.

Le deuxième interrupteur de signalisation 16 comprend également un système de contacts inverseurs 32,34,36 ayant un bras de contact 32 mobile à contact double coopérant avec deux contacts fixes 34,36, l'ensemble de ces contacts étant en liaison électrique avec un deuxième jeu de bornes 38,40,42 agencées sur l'autre face latérale étroite opposée du boîtier 12. L'état du deuxième interrupteur 16 permet de signaler l'ouverture sur défaut par déclenchement automatique du bloc disjoncteur (fonction SD). Seule la borne 38 est montrée en détail, les autres cinq bornes sont représentées par leurs plages de contact.The second signaling switch 16 also includes a reversing contact system 32,34,36 having a movable contact arm 32 with double contact cooperating with two fixed contacts 34,36, all of these contacts being in electrical connection with a second set of terminals 38, 40, 42 arranged on the other opposite narrow side face of the housing 12. The state of the second switch 16 makes it possible to signal the opening on fault by automatic tripping of the circuit breaker block (SD function). Only terminal 38 is shown in detail, the other five terminals are represented by their contact pads.

Le mécanisme 18 est composé d'une platine 44 mobile, en matériau isolant montée à pivotement limité sur un axe 46 fixe. La platine 44 est reliée mécaniquement à la manette 19 par l'intermédiaire d'une biellette 48 de transmission et d'un accrochage 50 formé par un levier d'encliquetage 52 coopérant avec un levier de déclenchement 54.The mechanism 18 is composed of a movable plate 44, of insulating material mounted with limited pivoting on a fixed axis 46. The plate 44 is mechanically connected to the lever 19 by means of a transmission link 48 and a latch 50 formed by a latching lever 52 cooperating with a trigger lever 54.

Le levier de déclenchement 54 est monté à pivotement entre une position armée et une position déclenchée. L'une des extrémités du levier double de déclenchement 54 permet d'assurer l'établissement ou la rupture de l'accrochage 50 avec le levier d'encliquetage 52, et l'autre extrémité est susceptible d'être actionnée par la barre de déclenchement incorporée dans le mécanisme de commutation du bloc disjoncteur.The trigger lever 54 is pivotally mounted between an armed position and a triggered position. One end of the double trigger lever 54 makes it possible to establish or break the coupling 50 with the latching lever 52, and the other end is capable of being actuated by the trigger bar incorporated in the circuit breaker block switching mechanism.

L'extrémité inférieure de la platine 44 porte un taquet 56 venant en engagement avec la partie intermédiaire du contact mobile 24 de l'interrupteur auxiliaire 14 en position de fermeture du bloc disjoncteur. Un ressort accumulateur 58 de traction est accroché entre le taquet 56 et un point fixe 60 du boîtier 12, de manière à provoquer le pivotement de la platine 44 dans le sens trigonométrique après rupture de l'accrochage 50 suite à un défaut. Le ressort accumulateur 58 sert de ressort d'actionnement du mécanisme 18.The lower end of the plate 44 carries a cleat 56 coming into engagement with the intermediate part of the movable contact 24 of the auxiliary switch 14 in the closed position of the circuit breaker block. A traction accumulator spring 58 is hooked between the cleat 56 and a fixed point 60 of the housing 12, so as to cause the pivoting of the plate 44 in the counterclockwise direction after breaking of the coupling 50 following a fault. The accumulator spring 58 serves as an actuating spring for the mechanism 18.

Sur l'axe 46 de la platine 44 est monté un levier support 62 ayant une première branche inférieure servant de porte-contact au bras de contact 32 de l'interrupteur de signalisation 16, et une deuxième branche supérieure coopérant avec un dispositif de signalisation 63. Une butée 64 de la platine 44 prend appui sur le levier support 62 en position fermé du bloc disjoncteur, en assurant un verrouillage positif du contact 32 contre le contact fixe 34.On the axis 46 of the plate 44 is mounted a support lever 62 having a first lower branch serving as a contact carrier for the contact arm 32 of the signaling switch 16, and a second upper branch cooperating with a signaling device 63 A stop 64 of the plate 44 bears on the support lever 62 in the closed position of the circuit breaker block, ensuring positive locking of the contact 32 against the fixed contact 34.

Le levier support 62 est doté d'une autre branche en saillie 66 susceptible de coopérer avec une rampe 68 circulaire solidaire de l'embase de la manette 20.The support lever 62 is provided with another projecting branch 66 capable of cooperating with a circular ramp 68 secured to the base of the lever 20.

Le fonctionnement du commutateur 10 double SD/OF de la figure 1 ressort clairement de la demande de brevet 8801151 précitée, et il suffit de rappeler que lors d'une ouverture automatique sur défaut, la barre de déclenchement du bloc disjoncteur provoque le déplacement vers la position déclenchée du levier de déclenchement 54, entraînant la rupture de l'accrochage 50. Sous l'action de détente du ressort 58, la platine 44 et le levier support 62 assurent le déplacement des deux bras de contact 24,32, venant respectivement en engagement contre les contacts fixes 22,36. Le premier interrupteur auxiliaire 14 indique l'ouverture des contacts principaux du bloc disjoncteur, et le deuxième interrupteur 16 signale l'ouverture automatique suite à un défaut ayant engendré un déclenchement. Ce défaut est signalé physiquement en face avant par le dispositif de signalisation 63.The operation of the double SD / OF switch 10 of FIG. 1 is clear from the aforementioned patent application 8801151, and it suffices to recall that during an automatic opening on fault, the trip bar of the circuit breaker block causes the displacement towards the triggered position of the trigger lever 54, causing the latching 50 to break. Under the spring action 58, the plate 44 and the support lever 62 move the two contact arms 24, 32, respectively engagement against stationary contacts 22.36. The first auxiliary switch 14 indicates the opening of the main contacts of the circuit breaker block, and the second switch 16 signals the automatic opening following a fault which has caused a trip. This fault is physically signaled on the front panel by the signaling device 63.

En l'absence de défaut, et lors d'une ouverture manuelle, la manette 19 du mécanisme 18 qui est accouplée à celle du bloc disjoncteur, se déplace de la position F de fermeture vers la position O d'ouverture (voir flèche sur figure 1), en entraînant la rampe 68 en direction de la saillie 66. Le levier support 62 est alors immobilisé en rotation par blocage positif de la saillie 66. La contact mobile 32 du deuxième interrupteur 16 reste en engagement contre le contact fixe 34, et n'indique pas de défaut.In the absence of a fault, and during manual opening, the handle 19 of the mechanism 18 which is coupled to that of the circuit breaker block, moves from the closed position F to the open position O (see arrow in figure 1), by driving the ramp 68 in the direction of the projection 66. The support lever 62 is then immobilized in rotation by positive locking of the projection 66. The movable contact 32 of the second switch 16 remains in engagement against the fixed contact 34, and does not indicate a fault.

Par contre, le premier interrupteur 14 change de position suite au pivotement de la platine 44 imposée par la biellette 48. Le contact mobile 24 est commuté vers le contact fixe 22, de manière à indiquer l'ouverture manuelle du bloc disjoncteur.By cons, the first switch 14 changes position following the pivoting of the plate 44 imposed by the link 48. The movable contact 24 is switched to the fixed contact 22, so as to indicate the manual opening of the circuit breaker block.

Selon l'invention, le commutateur 10 de la figure 1 est doté d'un dispositif de test 70 SD possédant un levier de commande 72 monté à pivotement sur un axe 74 entre une position active et une position inactive. L'une des extrémités du levier 72 est agencée en bouton test 76, dont l'enfoncement provoque le basculement dans le sens trigonométrique du levier 72 vers la position active, à l'encontre de la force de rappel d'une languette 78 élastique. Cette dernière constitue un ressort de rappel du levier 72 vers la position inactive (figure 1). L'extrémité libre du levier 72 à l'opposé du bouton test 76, est susceptible d'agir directement sur la lame du bras de contact 32 du deuxième interrupteur 16 de signalisation lorsque le levier 72 est actionné par le bouton test 76 vers la position active. Le test SD n'agit pas sur l'état du premier interrupteur 14, mais permet de vérifier le fonctionnement du circuit SD extérieur raccordé au deuxième jeu de bornes 38,40,42 de l'interrupteur 16, sans pour autant provoquer un déclenchement forcé du bloc disjoncteur. Lors du test, le bras de contact 32 est commuté dans le sens de la flèche T1 vers le contact fixe 36, (voir position en pointillé), et le reste du mécanisme 18 ne bouge pas. La position du levier support 62, de la platine 44 et de la manette 19 n'est pas modifiée. Le dispositif de signalisation 63 reste également inactif après le test SD. Il en résulte que l'opération de test SD ne nécessite pas de réarmement local du mécanisme 18 ou de remise à zéro du dispositif de visualisation 63.According to the invention, the switch 10 in FIG. 1 is provided with a test device 70 SD having a control lever 72 pivotally mounted on an axis 74 between an active position and an inactive position. One end of the lever 72 is arranged as a test button 76, the depression of which causes the tilting in the trigonometric direction of the lever 72 towards the active position, against the return force of an elastic tongue 78. The latter constitutes a return spring of the lever 72 to the inactive position (Figure 1). The free end of the lever 72 opposite the test button 76 is capable of acting directly on the blade of the contact arm 32 of the second signaling switch 16 when the lever 72 is actuated by the test button 76 towards the position active. The SD test does not act on the state of the first switch 14, but makes it possible to verify the operation of the external SD circuit connected to the second set of terminals 38, 40, 42 of the switch 16, without however causing a forced trip. of the circuit breaker block. During the test, the contact arm 32 is switched in the direction of the arrow T1 towards the fixed contact 36, (see position in dotted lines), and the rest of the mechanism 18 does not move. The position of the support lever 62, the plate 44 and the lever 19 is not changed. The signaling device 63 also remains inactive after the SD test. As a result, the SD test operation does not require local resetting of the mechanism 18 or resetting of the display device 63.

Le bloc disjoncteur reste fermé durant l'opération de test SD, évitant de ce fait toute interruption du circuit de puissance. Le test SD permet de vérifier le fonctionnement des automatismes connectés dans le circuit SD extérieur. Ce contrôle intervient généralement lors de l'installation d'un coffret électrique, et est effectué par l'installateur avant la mise en place du plastron 80. L'emplacement interne du levier de commande 72 du test dans le boîtier 12 est choisi pour que le bouton test 76 soit caché par le plastron 80 du coffret. Après le montage final du coffret, le client n'a pas accès au bouton test 76, et aux deux jeux de bornes.The circuit breaker block remains closed during the SD test operation, thereby preventing any interruption of the power circuit. The SD test is used to check the operation of the automations connected in the external SD circuit. This control generally occurs during the installation of an electrical box, and is carried out by the installer before the installation of the faceplate 80. The internal location of the control lever 72 of the test in the housing 12 is chosen so that the test button 76 is hidden by the front plate 80 of the box. After the final assembly of the box, the customer does not have access to the test button 76, and to the two sets of terminals.

L'axe 74 du levier de commande 72 se trouve sous la rampe 68 de la manette 19.The axis 74 of the control lever 72 is located under the ramp 68 of the lever 19.

La réalisation de la figure 2 concerne un commutateur 100 simple SD, dans lequel le circuit OF du premier interrupteur auxiliaire 14 de la figure 1 a été supprimé avec le premier jeu de bornes associées. Le reste du mécanisme 18 est conservé, ainsi que le dispositif de test 70 dont le levier de commande 72 agit directement sur la lame du contact mobile 32 de l'interrupteur 16 (voir flèche T1). Le fonctionnement de test SD est identique à celui du dispositif de la figure 1.The embodiment of FIG. 2 relates to a simple switch 100 SD, in which the OF circuit of the first auxiliary switch 14 in FIG. 1 has been deleted with the first set of associated terminals. The rest of the mechanism 18 is preserved, as well as the test device 70, the control lever 72 of which acts directly on the blade of the movable contact 32 of the switch 16 (see arrow T1). The SD test operation is identical to that of the device in FIG. 1.

Le commutateur 110 simple OF de la figure 3 est doté de l'interrupteur 14. Le mécanisme 118 a été également modifié, notamment l'agencement du levier support 62 avec la suppression de la saillie 66, et l'adjonction d'une patte 112 inférieure qui coopère directement avec le contact mobile 24 de l'interrupteur 14. Le deuxième interrupteur 16 est supprimé dans cette variante. Le levier support 62 sert avantageusement de levier de commande à un dispositif de test 170 OF, dont le bouton test 176, situé à l'opposé de la patte 112, est confondu avec le dispositif de signalisation 63 de la figure 1 ou 2.The simple switch 110 OF in FIG. 3 is provided with the switch 14. The mechanism 118 has also been modified, in particular the arrangement of the support lever 62 with the removal of the projection 66, and the addition of a tab 112 lower which cooperates directly with the movable contact 24 of the switch 14. The second switch 16 is eliminated in this variant. The support lever 62 advantageously serves as a control lever for a test device 170 OF, the test button 176 of which, located opposite the tab 112, is coincident with the signaling device 63 of FIG. 1 or 2.

Le but de ce test OF consiste à tester les automatismes connectés dans le circuit OF du premier jeu de bornes 26,28,30, sans fermer le circuit principal du bloc disjoncteur.The purpose of this OF test consists in testing the automatic devices connected in the OF circuit of the first set of terminals 26,28,30, without closing the main circuit of the circuit breaker block.

La fonction test OF sur le commutateur 110 de la figure 3 s'effectue de la manière suivante:The OF test function on the switch 110 in FIG. 3 is carried out as follows:

Le bloc disjoncteur se trouve en position d'ouverture, et le contact mobile 24 de l'interrupteur 14 est contre le contact fixe 22. Un déplacement dans le sens des aiguilles d'une montre du levier 62 pivotant vers la position active par l'action du bouton test 176, amène la patte 112 contre le contact mobile 24, et l'entraine vers le contact fixe 20 opposé (voir flèche T2), sans que la platine 44 et la manette 19 ne bougent. L'opération de test OF provoque une fermeture du circuit auxiliaire OF, alors que le circuit principal du bloc disjoncteur reste ouvert. Un ressort 178 de rappel sollicite automatiquement le levier 62 vers la position inactive lors du relâchement du bouton test 176.The circuit breaker block is in the open position, and the movable contact 24 of the switch 14 is against the fixed contact 22. A movement in the clockwise direction of the lever 62 pivoting towards the active position by the action of the test button 176, brings the tab 112 against the movable contact 24, and drives it towards the opposite fixed contact 20 (see arrow T2), without the plate 44 and the lever 19 not moving. The OF test operation causes the OF auxiliary circuit to close, while the main circuit of the circuit breaker block remains open. A return spring 178 automatically biases the lever 62 towards the inactive position when the test button 176 is released.

En référence à la figure 4, un commutateur 200 double OF/OF comporte les deux interrupteurs 14,16 avec le mécanisme 118 de la figure 3. Le contact mobile 32 du deuxième interrupteur 16 est solidaire du levier support 44. L'opération de test s'opère d'une manière identique à celle du commutateur 110 précédent, mais dans ce cas, le levier 62 du test agit simultanément sur les deux contacts mobiles 32,24 pour les entraîner dans le sens des flèches T2 vers les contacts fixes 34,20. L'actionnement du bouton test 176 vers la position active provoque alors un test OF simultané sur deux circuits auxiliaires indépendants, sans nécessiter la fermeture du bloc disjoncteur, et un réarmement local du mécanisme 118.With reference to FIG. 4, a double OF / OF switch 200 comprises the two switches 14, 16 with the mechanism 118 of FIG. 3. The movable contact 32 of the second switch 16 is secured to the support lever 44. The test operation operates in a manner identical to that of the preceding switch 110, but in this case, the lever 62 of the test acts simultaneously on the two movable contacts 32, 24 to drive them in the direction of the arrows T2 towards the fixed contacts 34, 20. The actuation of the test button 176 towards the active position then causes a simultaneous OF test on two independent auxiliary circuits, without requiring the closing of the circuit breaker block, and a local reset of the mechanism 118.
