選定したことを特徴とする多重選択検出回路。 In a multiple selection detection circuit that detects that at least two input points among a plurality of individually selectable input points are selected at the same time, one side of the resistor bridge is provided with a resistor in the selected state corresponding to each input point. The contacts to be closed are connected in parallel through a resistor, and an output relay is connected between the other diagonal points, not between the diagonal points to which the power supply of the resistor bridge is connected, and the individual resistance values of the resistor bridge are A multiple selection detection circuit characterized in that the output relay is selected to satisfy a bridge equilibrium condition so that the output relay is not activated when only one input point is selected.
