路。 A circuit that includes a plurality of switch elements and selects and derives one of the signals introduced into the input terminal of each switch element, wherein the input terminal of each switch element and one terminal of a DC power source are connected to each other. A first resistor is connected between each of them, a switching diode is connected between each of the input terminals and the other terminal of the power source, and a commonly connected output terminal of each of the switch elements and the other terminal of the power source are connected. A second resistor is connected between the first and second resistors so that the conduction voltage of each of the switch diodes is higher than the DC bias voltage of each of the switch elements due to the voltage division of the first and second resistors. Selected signal switching circuit.
