Abstract

L'invention concerne un circuit de commande d'une machine comprenant plusieurs boutons-poussoirs. Chaque bouton-poussoir comporte un contact de travail et un contact de repos. Un circuit de contrôle est connecté en dérivation sur chacun des contacts. Chaque circuit de contrôle comporte deux sorties qui passent alternativement au niveau haut et au niveau bas quand le contact contrôlé s'ouvre et se ferme. Des circuits logiques combinent les sorties de tous les circuits de contrôle et produisent un signal dans le cas où un dérangement se produit. L'invention s'applique notamment à la commande des presses de découpage, d'emboutissage, etc.
