A power device for an automotive vehicle comprises an interlock switch, a crash sensor for detecting impact of an automotive vehicle, an interlock relay controlled and turned ON and OFF by the interlock switch, and a contactor for interrupting an output circuit when the interlock relay is turned OFF. In the power device, when the interrupting signal is outputted from the crash sensor, or when the interlock switch is turned OFF from ON, the contactors are turned OFF to interrupt the output circuit. Further, the power device comprise a switching element connected to an exciting coils of the contactors in series and turned ON and OFF by an interrupting signal of the crash sensor. When the crash sensor outputs the interrupting signal, the contactors are turned OFF by the switching elements.
