An electric switching device for switching over a current path from a first electric conductor (7) to a second electric conductor (8), comprising a first contact member (1) and a set of second contact members (2, 3, 4, 5), which are arranged after each other along a path. The first contact member (1) is movably arranged in relation to the second contact members along said path for the achievement of an electric connection with each of these. The set of second contact members comprises two main contact members (2, 5), each of which being connected to one of said conductors (7, 8), and at least one switching contact member (3, 4) arranged between the main contact members. The first contact member (1) is arranged to allow the simultaneous contacting of two adjacent second contact members. The switching device further comprising an arrangement (10) connected to said switching contact member (3, 4) and said two conductors (7, 8) for connecting and disconnecting said switching contact member (3, 4) to and from, respectively, said two conductors (7, 8). |
