Abstract: A time division multiplexing load control system having a central controller unit for controlling individual terminal units to connect and disconnect loads connected respectively thereto and manual switch means for directly controlling the loads without reverting to the central controller unit is disclosed. A plurality of terminal units are connected through a shared line to the central controller unit to be controlled thereby so as to turn on/off the loads connected to respective terminal units. Each terminal unit connecting the loads is provided with a load-switching circuit for actuating respective load driving relays incorporated therein to connect and disconnect the loads. The load-switching circuit includes switch means which responds to output data signal from the central controller unit to open and close the load-switching circuit for the ON/OFF drive of the load remote from the central controller unit.
