Description

  

  Dispositif pour la commande d'au moins un contact par des moyens magnétiques    Le brevet principal a pour objet un dispositif pour  la commande d'au moins un contact par des moyens  magnétiques, ce contact étant formé par des éléments  élastiques sensibles auxdits moyens magnétiques, carac  térisé par le fait que     ce    dispositif comprend un circuit  magnétique qui se compose d'au moins un aimant per  manent dont chaque pôle est relié à une pièce polaire,  l'une de     ces        pièces    au moins étant susceptible d'occuper  deux positions, correspondant à l'ouverture, respective  ment la fermeture dudit circuit,

   de manière que l'ouver  ture de     ce    circuit crée un champ de dispersion provo  quant la     fermeture    dudit     contact.     



  Les éléments élastiques dudit contact sont sensibles  aux     surcharges    de courant,     ce    qui limite la durée de vie du  dispositif.  



  La présente invention a pour but d'augmenter la       durée    de vie du dispositif à une valeur pratiquement  illimitée. Elle a pour objet un dispositif pour la com  mande d'au moins un contact par des moyens magnéti  ques selon la revendication du brevet principal, caracté  risé par le fait qu'il comprend en outre un élément de  protection monté en parallèle avec le contact.  



  Le dessin annexé représente, à titre d'exemple, une  forme d'exécution de l'invention.  



  Les éléments 1, 2, 3, 4, 5 et 6 du dispositif représenté       correspondent    à ceux de la     fig.    1 du brevet principal. Les  bornes du contact 6 sont     reliées,    d'une part, à une résis  tance 20 et, d'autre part, à l'une des électrodes d'un         triac    21 disposé en série dans le circuit du courant à  commuter, l'électrode de commande 22 du     triac    étant       reliée    à la     résistance    20.

   Le contact 6 n'a plus ainsi à  commuter le courant principal du circuit d'utilisation  mais seulement le courant de     commande    du     triac,    ce  courant étant     beaucoup    plus faible que le     courant    prin  cipal. La durée de vie du contact 6, et avec lui celle de  l'ensemble du     dispositif,    devient pratiquement     illimitée.     



  Dans le cas d'un fonctionnement en courant continu,  on peut utiliser comme élément de     protection    une diode       placée    en     parallèle    sur le contact 6. Lorsque le contact 6  ne doit commuter qu'un courant alternatif de faible       valeur,    une     protection        efficace    est aussi possible au  moyen d'une résistance     VDR        (Varistor)    montée en paral  lèle sur le contact 6.  



  Ces deux éléments semi-conducteurs ne sont cités  qu'à titre d'exemple et peuvent être remplacés selon les.  cas par tout autre élément connu.



  Device for controlling at least one contact by magnetic means The main patent relates to a device for controlling at least one contact by magnetic means, this contact being formed by elastic elements sensitive to said magnetic means, such as terized by the fact that this device comprises a magnetic circuit which consists of at least one permanent magnet, each pole of which is connected to a pole piece, at least one of these pieces being capable of occupying two positions, corresponding to the opening, respectively the closing of said circuit,

   so that the opening of this circuit creates a dispersion field causing the closing of said contact.



  The elastic elements of said contact are sensitive to current overloads, which limits the service life of the device.



  The present invention aims to increase the lifetime of the device to a practically unlimited value. It relates to a device for controlling at least one contact by magnetic means according to the claim of the main patent, characterized in that it further comprises a protection element mounted in parallel with the contact.



  The accompanying drawing represents, by way of example, one embodiment of the invention.



  The elements 1, 2, 3, 4, 5 and 6 of the device shown correspond to those of FIG. 1 of the main patent. The terminals of contact 6 are connected, on the one hand, to a resistor 20 and, on the other hand, to one of the electrodes of a triac 21 arranged in series in the current circuit to be switched, the electrode control 22 of the triac being connected to resistor 20.

   Contact 6 thus no longer has to switch the main current of the user circuit but only the triac control current, this current being much lower than the main current. The service life of contact 6, and with it that of the entire device, becomes practically unlimited.



  In the case of direct current operation, a diode placed in parallel with contact 6 can be used as a protection element. When contact 6 should only switch an alternating current of low value, effective protection is also possible. by means of a VDR resistor (Varistor) mounted in parallel on contact 6.



  These two semiconductor elements are cited only by way of example and can be replaced according to. case by any other known element.
