Abstract
The selective interconnection of tracks or slots coming together at a junction in a conveying system with push and pull operable conveying chains without return strands running in chain channels is accomplished by a switch constructed as a straight prism (21) mounted in a rotary manner. The prism has differently shaped chain channel portions (23', 23') on different ones of its sides. By rotating the prism (21) about its median longitudinal axis (22), that chain channel portion is positioned in the junction, which has the channel portions shaped to obtain the desired connection between the chain channel of selected entering and exiting tracks.
