Abstract
L'INVENTION A TRAIT A UN INTERRUPTEUR ELECTRIQUE A TOUCHE. DANS CET INTERRUPTEUR, LE SUPPORT 8 DU PONT DE CONTACT PIVOTE DANS LE BOITIER 1, 3 AUTOUR D'UN AXE TRANSVERSAL AU SENS DE DEPLACEMENT DE LA TOUCHE 22; LE POUSSOIR 20 EST SOLIDAIRE DU SUPPORT 8 DU PONT; LA TOUCHE PRESENTE, SUR LE COTE TOURNE VERS LE POUSSOIR 20, DEUX SURFACES DE COMMANDE 33, 34, QUI SONT APPROXIMATIVEMENT ALIGNEES SUR L'EXTREMITE LIBRE DU POUSSOIR 20 DANS L'UNE OU L'AUTRE POSITION EXTREME DE SA PLAGE DE PIVOTEMENT; LES DEUX SURFACES DE COMMANDE 33, 34 SONT REUNIES PAR UNE SURFACE INTERMEDIAIRE 35 EN FORME DE SELLE, LE DOS DE LA SELLE FAISANT UN ANGLE AIGU AVEC LE PLAN DE PIVOTEMENT DU POUSSOIR 20; LES SURFACES DE COMMANDE 33, 34 ET LES SURFACES INTERMEDIAIRES 35 ONT UNE INCLINAISON QUI SE TRADUIT, LORS DE L'ENFONCEMENT DE LA TOUCHE 22 PAR UN BASCULEMENT DANS L'AUTRE POSITION EXTREME ET PAR UNE DEVIATION ELASTIQUE HORS DU PLAN DE PIVOTEMENT.THE INVENTION RELATES TO AN ELECTRIC KEY SWITCH. IN THIS SWITCH, THE SUPPORT 8 OF THE CONTACT BRIDGE SWIVELS IN THE BOX 1, 3 AROUND A TRANSVERSAL AXIS IN THE DIRECTION OF MOVEMENT OF THE KEY 22; THE PUSHBUTTON 20 IS IN ONE OF THE BRIDGE SUPPORT 8; THE BUTTON PRESENT ON THE SIDE TURNS TOWARDS THE PUSHBUTTON 20, TWO CONTROL SURFACES 33, 34, WHICH ARE APPROXIMATELY ALIGNED WITH THE FREE END OF THE PUSHBUTTON 20 IN EITHER EXTREME POSITION OF ITS PIVOTING RANGE; THE TWO CONTROL SURFACES 33, 34 ARE JOINED BY AN INTERMEDIATE SURFACE 35 IN THE FORM OF A SADDLE, THE BACK OF THE SADDLE MAKING AN ACUTE ANGLE WITH THE PIVOTING PLANE OF THE PUSHBUTTON 20; THE CONTROL SURFACES 33, 34 AND THE INTERMEDIATE SURFACES 35 HAVE AN INCLINATION WHICH IS TRANSLATED WHEN KEY 22 IS DEPRESSED BY A TILT INTO THE OTHER EXTREME POSITION AND BY AN ELASTIC DEVIATION OUTSIDE THE PIVOT PLANE.
