ABSTRACT:
A data transfer switch has a casing and a linking unit which is rotatably provided inside the casing and which includes a plurality of interconnected linking pieces. Each of the linking pieces is a relatively thin cylindrical insulator and has one side which is provided with an axial tubular projection that extends toward an adjacent one of the linking pieces so as to form an annular groove between each of the linking pieces and the adjacent one of the linking pieces. A plurality of connector pin sets are mounted on a side wall of the casing. Each of the connector pin sets has a plurality of connector pins which respectively extend into a corresponding annular groove of the linking unit. A conductive pattern is provided on each of the linking pieces at each annular groove. Rotation of the linking unit from a first angular position to a second angular position causes the conductive pattern to break electrical connection between a first one of the connector pins sets and a second one of the connector pin sets and make electrical connection between the first one of the connector pin sets and a third one of the connector pin sets.
