PROBLEM TO BE SOLVED: To provide a small-scale and inexpensive power/signal multiplex transmission system that can transmit a high power signal with a signal superimposed on it. SOLUTION: The power/signal multiplex transmission system is provided with switches SW1-SW3, an oscillation circuit 12 that generates AC power with a current specific to an operated switch, when any of the switches SW1-SW3 is operated; transformers 10, 20 that receive and output the AC power; and a smoothing circuit 21 that generates and outputs a signal corresponding to the current of the AC power outputted from the transformers 10, 20 and rectifies and outputs the AC power outputted from the transformers 10, 20.
