Abstract: A switching device (1) for an encapsulated electric power distribution switchgear comprising a switch (10), an electrically conductive housing (20) to which the switch is mounted, and which housing (20) comprises an opening (24) that leads into the housing (20). The switch comprises a first electric contact (12) connected to a first conductor (16) and a second electric contact (14) connected to a second conductor (18), the second contact being movable in relation to the first contact and in relation to the housing. The further comprises an operating shaft (30) of electrically insulating material being rotatable about its longitudinal axis Y in relation to the housing, and which is inserted into the housing via the opening (24), and an actuator member (40) located inside the housing and having a first end (42) coupled to the shaft and a second (44) end coupled to the second contact (14). The actuator member is made of an electrically insulating material. The shaft (30) extends through the opening (24) and into the housing without directly contacting the housing (20) and is supported in the housing (20) by the actuator member. The actuator member (40) is movably supported in the housing (20) at a connection area (26) that forms an interface (27) between the actuator member and the housing. The interface is located at a distance D from the longitudinal axis Y of the shaft that is longer than a distance d between the longitudinal axis Y of the shaft and a circumferential edge (23) that delimits the opening (24) in the housing, which first and second distances are measured in the same radial direction in relation to the longitudinal axis Y.
