Switch for a conveying line for transporting a laboratory diagnostic vessel carrier

A switch for conveying a laboratory diagnostic vessel carrier from a first line portion of a conveying line to a second line portion of the conveying line, the switch comprising:

• a curved first guiding surface, wherein the curved first guiding surface is curved with a radius corresponding to a width of the first line portion;
• and
• a second guiding surface, wherein the switch is moveable between a first position, in which the laboratory diagnostic vessel carrier is transportable continuously along the curved first guiding surface from the first line portion to the second line portion, and a second position, in which the laboratory diagnostic vessel carrier is further transportable continuously along the second guiding surface on the first line portion, wherein the second guiding surface is flush with a boundary of the first line portion, wherein the curved first guiding surface and the second guiding surface are configured to engage the laboratory diagnostic vessel carrier, and wherein the curved first guiding surface and/or the second guiding surface comprises a rib-shaped protrusion extending from the curved first guiding surface and/or the second guiding surface configured to engage the laboratory diagnostic vessel carrier.
