Abstract: An exemplary HV switching device includes a casing having at least a first fixed contact and a second fixed contact that are spaced apart from each other and can be connected to two corresponding power terminals. A first movable contact and a second movable contact are spaced apart from each other and actuated for coupling the first fixed contact and the second fixed contact, respectively. At least one of the first fixed contact and first movable contact has a shape for coupling the first movable contact to the first fixed contact in at least a first coupling position and a second coupling position which are spaced apart, and at least one of the second fixed contact and second movable contact has a shape for coupling the second movable contact to the second fixed contact in at least a third coupling position and a fourth coupling position which are spaced apart.
