A time switch for a time division switch has a function to exchange time slots as well as functions of bit are conversion and multiplexing or demultiplexing. A first stage time switch comprises a channel memory capable of sequential writing and random reading and a converter for converting a data read from the channel memory to a universal signal in accordance with a conversion mode designation. A final stage time switch comprises a channel memory capable of random writing and sequential reading and a control circuit for designating a write bit position of the channel memory in accordance with a write mode designation. An economic time switch having a high flexibility to a traffic variation among bearer signals is provided.
