Abstract

A switching device (2) comprising a frame (201), a first fixed contact member (34) having a first contact area (341), and a first movable contact member (4) having a first contact arm (41) provided with a contact area. The first movable contact member (4) is adapted to pivot relative to the frame (201) around a first pivoting axis (45) between a first position and a second position. The switching device (2) comprises a spreader member (6) that is adapted to provide a first intermediate position for the first movable contact member (4) in which a projection of the contact area of the first contact arm (41) overlaps at least partially with a projection of the first contact area (341) on a switch plane perpendicular to the first pivoting axis (45) while the contact area of the first contact arm (41) is spaced apart from the first contact area (341).
