Un appareil de commutation (1), visible aux figures 1 et 6, comporte deux demi-boîtiers isolants (2) et (3) sensiblement symétriques par rapport au plan médian PP', le long duquel s'appliquent ces demi-boîtiers. Une fois assemblé cet appareil comporte une face de fixation (3') passant par le plan RR' et coopérant par exemple avec un profilé normalisé, une face supérieure (4) placée dans un plan VV parallèle à RR', et deux faces latérales (5) (6) terminant deux régions d'extrémités opposées (7) (8) de l'appareil. A switching device (1), visible in Figures 1 and 6, comprises two insulating half-housings (2) and (3) substantially symmetrical with respect to the median plane PP ', along which these half-housings apply. Once assembled, this device comprises a fixing face (3 ') passing through the plane RR' and cooperating for example with a standardized profile, an upper face (4) placed in a plane VV parallel to RR ', and two lateral faces ( 5) (6) terminating two opposite end regions (7) (8) of the device.

Dans chacune des régions (7,8) est disposée une pièce isolante (9) respectivement (10), qui est maintenue entre les de-mi-boîtiers, ces deux pièces réalisant la fermeture d'un volume intérieur (11) dans lequel sont placés: un électro-aimant (12) coopérant avec une armature (13) placé au voisinage de la face (4) et sensiblement parallèlement à celli-ci, un poussoir (14) situé dans un plan QQ', visible à la figure 2, qui est per- In each of the regions (7,8) is disposed an insulating part (9) respectively (10), which is held between the half-housings, these two parts closing an interior volume (11) in which are placed: an electromagnet (12) cooperating with a frame (13) placed in the vicinity of the face (4) and substantially parallel to it, a pusher (14) located in a plane QQ ', visible in FIG. 2 , which is per-

Par ailleurs deux ouvertures telles que (39,40) voir figures 2,3 et 5, débouchent dans chaque face latérale (5,6) en traversant chaque pièce isolante (9) respectivement (10), pour donner à des conducteurs extérieurs la possibilité d'accéder d'une s part avec un excellent isolement aux entrées de connexion telles que (59) respectivement (60) des bornes (33) (34) et d'autre part, sans ambiguité à l'ensemble des bornes grâce à leur éta-gement, celui-ci permettant en outre un accèes aléatoire à chaque borne. Furthermore, two openings such as (39.40) see Figures 2,3 and 5, open in each side face (5,6) by crossing each insulating part (9) respectively (10), to give external conductors the possibility to access on the one hand with excellent insulation to the connection inputs such as (59) respectively (60) of the terminals (33) (34) and on the other hand, unambiguously to all of the terminals thanks to their floor, this also allowing random access to each terminal.

io La région (17), voir figure 1, dans laquelle sont placés côte à côte des interrupteurs (15,16), est avantageusement située d'une part, entre deux bornes de circuit voisines telles que (19) (21) et l'électro-aimant (12) et d'autre part entre une borne de commande (34) placée dans la même région (7) et la face de fi-i5 xation (3'). Une espace résiduel (41) placé entre cette face de fixation (3') et l'électro-aimant (12) peut être utilisée pour loger pendiculaire à PP' et à RR' et un système de deux interrupteurs un organe porte-contact représenté schématiquement par (42) (15,16) disposés dans une région (17) du volume (11). qui peut être guidé par exemple autour d'un pivot (43) placé io The region (17), see FIG. 1, in which the switches (15,16) are placed side by side, is advantageously located on the one hand, between two neighboring circuit terminals such as (19) (21) and l electromagnet (12) and on the other hand between a control terminal (34) placed in the same region (7) and the fi-i5 xation face (3 '). A residual space (41) placed between this fixing face (3 ') and the electromagnet (12) can be used to accommodate pendulum to PP' and to RR 'and a system of two switches a contact-holding member shown schematically by (42) (15,16) arranged in a region (17) of the volume (11). which can be guided for example around a pivot (43) placed

PP', ces plans étant sensiblement symétriques par rapport à PP'. PP ', these planes being substantially symmetrical with respect to PP'.

Deux bornes de circuit voisines (18) (20) sont maintenues dans des alvéoles telles que (28) figure 5, constituées par des demi-logements tels que (29) et (30) appartenant respectivement à une pièce isolante telle que (10) et à un demi-boîtier voisin, et peuvent recevoir des conducteurs extérieurs par des ouvertes telles que (31) et (32) voir figure 3, qui sont placées commes ces bornes dans un plan SS' parallèle à RR'. Une distance «b» sépare deux bornes de circuit d'une même paire. Two neighboring circuit terminals (18) (20) are held in cells such as (28) FIG. 5, constituted by half-housings such as (29) and (30) belonging respectively to an insulating part such as (10) and to a neighboring half-box, and can receive external conductors through openings such as (31) and (32) see FIG. 3, which are placed as these terminals in a plane SS 'parallel to RR'. A distance "b" separates two circuit terminals of the same pair.

Deux bornes de commande (33,34) qui sont chacune électriquement reliées aux connexions d'une bobine (35) de l'électro-aimant, sont placées dans le plan médian PP', et dans un plan TT' parallèle à RR' qui est plus éloigné de la face de fixation (3') que ne l'est le plan SS'. Two control terminals (33,34) which are each electrically connected to the connections of a coil (35) of the electromagnet, are placed in the median plane PP ', and in a plane TT' parallel to RR 'which is further from the fixing face (3 ') than is the plane SS'.

Ces bornes de commande chacune par exemple une portion transversale telle que (36) voir figure 1, coopérant avec des encoches telles que (37,38) de chaque demi-boîtier pour en assurer la fixation. Une distance «a» mesurée parallèlement à «b» sépare les deux bornes de commande. These control terminals each for example a transverse portion such as (36) see Figure 1, cooperating with notches such as (37,38) of each half-housing to ensure the fixing. A distance "a" measured parallel to "b" separates the two control terminals.

Un léger intervalle (50) placé entre un bord (54) du poussoir (14) et le demi-boîtier (2) voisin permet le passage d'un conducteur (51) qui relie la borne de commande à la bobine. A slight gap (50) placed between an edge (54) of the pusher (14) and the neighboring half-housing (2) allows the passage of a conductor (51) which connects the control terminal to the coil.

30 L'isolement entre les bornes de commande et les bornes de circuit est de plus amélioré par la disposition de canaux d'accès tels que (55,56) débouchant sur les faces supérieures (57, 58) des extrémités à un niveau inférieur à VV', voir figures 5 et 6 et qui sont ménagés sentre les demi-boîtiers isolants (2,3) et The insulation between the control terminals and the circuit terminals is further improved by the provision of access channels such as (55,56) opening onto the upper faces (57, 58) of the ends at a level below VV ', see Figures 5 and 6 and which are arranged between the insulating half-housings (2,3) and

The axes of all the clamping screws will advantageously be mutually parallel and perpendicular to the fixing face (3).

Compte-tenu de la dimension des bornes leur isolement efficace et une grande clarté de leur fonction ont été obtenus grâce au fait que «a» étant plus petit «b» et SS' étant compris entre TT' et RR', toutes les entrées de connexion et tous les accès aux vis de serrage ont été placés en quinconce. Given the size of the terminals, their efficient isolation and great clarity of their function have been obtained thanks to the fact that "a" being smaller "b" and SS 'being between TT' and RR ', all the inputs of connection and all accesses to the clamping screws have been staggered.
