Abstract

INTERRUPTEUR ROTATIF MULTIPOLAIRE. Un interrupteur rotatif multipolaire à enceinte (10) en matière isolante moulée, portant sur son pourtour interne des contacts fixes d'entrée et de sortie (15,16) et d'un contact fixe de mise à la terre (17), comporte une cloison isolante (29) intercalée entre le contact d'entrée (15) et le contact de mise à la terre (17). Un arbre de commande porte les ponts de contacts en forme de couteau constitués de deux lames s'étendant parallèlement, et dont les extrémités sont agencées en pinces. Les lames de contacts comportent dans leur partie centrale une échancrure qui évite toute venue en contact lors d'un fléchissement et de ce fait toute annulation de l'effet d'attraction dû aux forces électrodynamiques. Se référer à la figure 4.MULTIPOLAR ROTARY SWITCH. A multi-pole rotary switch with enclosure (10) of molded insulating material, bearing on its internal periphery fixed input and output contacts (15,16) and a fixed earthing contact (17), comprises a insulating partition (29) interposed between the input contact (15) and the earthing contact (17). A control shaft carries the knife-shaped contact bridges consisting of two blades extending in parallel, the ends of which are arranged in the form of clamps. The contact blades have in their central part a notch which prevents any coming into contact during a bending and therefore any cancellation of the attraction effect due to electrodynamic forces. Refer to figure 4.
