Abstract
Improvements in the construction of electrical switches with extinguishing chambers, which contain connection contacts that are movable in relation to each other, between which an electric arc passes, and that in a transverse direction to the plane of translation of the connection contacts is closed by bodies of insulating material, and containing extinguishing plates against which the electric arc moves through conductive parts of the chamber wall, characterized in that the extinguishing channel between the connection contacts and the extinguishing plates is provided, transverse to the plane of movement of the connecting contacts and transverse to the plane of movement of the arc in the direction of movement of the arc, of a nozzle-shaped section narrowing with a section widening below which is dimensioned for an aerodynamic acceleration of the electric arc, which penetrates behind the mouth a of the nozzle between the extinguishing plates.
