Abstract
A switching device for low-voltage or medium-voltage applications including: one or more electric poles; for each electric pole, at least a fixed contact and at least a movable contact, each movable contact being reversibly movable between a coupled position, at which the movable contact is coupled with a corresponding fixed contact, and an uncoupled position, at which the movable contact is separated from the fixed contact, wherein a separation gap is present between the movable contact and the fixed contact, when the movable contact is in the uncoupled position. The switching device includes, for each electric pole, at least an arc-diverting element made of electrically insulating material.
