PROBLEM TO BE SOLVED: To provide a switch operation device 1 capable of preventing erroneous detection of a signal level when water leakage or the like occurs.SOLUTION: A switch operation device 1 includes: an output part P2 for outputting a switch signal: five electric paths EP1 to EP5 which are connected to the output part P2 and alternatively energized; and a submergence-time control circuit 12 which is operated during submersion of the switch operation device 1 to reduce resistance of the electric path EP2 as a control target electric path. The electric path EP2 includes a switch S2 and a resistor R1 which are connected in series and serves as an electric path EP2S during the submersion.SELECTED DRAWING: Figure 1F
