Abstract (en)
[origin: US2020194193A1] A device for switching an electric current with separable electrical contacts includes a switching mechanism including: a switching shaft that is coupled to a mobile electrical contact; a trip hook that is pivotably mounted on a fixed support of the mechanism; a linking system coupling the switching shaft to the trip hook. The linking system includes a first pair of connecting rods that are pivotably mounted on the trip hook and a second pair of connecting rods that are mounted so as to pivot with a crank of the switching shaft. The first connecting rods are connected to the second connecting rods with a single axis of articulation which forms a pivot link between the first connecting rods and the second connecting rods.
