  Commutateur à bouton-poussoir, à dispositif de plombage. 



   La présente invention se rapporte à un dispositif de plombage pour des commutateurs automatiques qui sont action- nés au moyen d'un bouton-poussoir. Suivant cette invention, on visse sur le bouton-poussoir un écrou qui est bloqué, de façon à être empêché de tourner en sens inverse, par une vis plombée. 



   Le dessin représente un exemple de réalisation de l'in- vention. On n'a représenté que les pièces du commutateur au- tomatique intervenant pour l'invention. Le bouton-poussoir a est pourvu extérieurement d'un filetage sur lequel se visse l'écrou câpres que le commutateur a été fermé. Si alors le

 commutateur automatique a fonctionné, une remise en circuit ne peut se faire que lorsque l'écrou b a été retiré ou a été dé- vissé suffisamment pour que le bouton-poussoir a puisse être re- poussé. L'écrou b est mis à l'abri d'un enlèvement non autorisé par la vis plombée c. Le cordon de plombage est passé d'une part à, travers un trou de la tête c de la vis, d'autre part à travers   lbeillet   de plombage d prévu sur l'écrou b.

  Push-button switch, with sealing device.



   The present invention relates to a sealing device for automatic switches which are actuated by means of a push button. According to this invention, a nut is screwed onto the push-button which is locked, so as to be prevented from turning in the opposite direction, by a lead screw.



   The drawing shows an exemplary embodiment of the invention. Only the parts of the automatic switch involved in the invention have been shown. The push-button a is provided on the outside with a thread onto which the cap nut is screwed that the switch has been closed. If then the

 automatic switch has operated, it can only be switched on when nut b has been removed or has been unscrewed enough so that push-button a can be pushed back. The nut b is protected from unauthorized removal by the lead screw c. The sealing bead is passed on the one hand through a hole in the head c of the screw, on the other hand through the sealing bezel d provided on the nut b.
