A path finding system for a telephone switching system having a plurality of reed relay matrix stages is described. Different groups of junctors are connected to different matrices of the stage at one end of the system, while different matrices of the stage at the opposite end of the system are connected to line circuits. Links are established through the stage at the junctor end of the system by connecting a free junctor to its associated matrix and then scanning the matrix associated with the free junctor to rapidly select a free link therein. Connections are then automatically extended through the remaining stages to the line circuit of the subscriber with respect to which communication services are desired.
