<P>PROBLEM TO BE SOLVED: To provide a downsized direct current plug with small power loss. <P>SOLUTION: A direct current plug comprises: an input terminal A and an input terminal B for connection with an outlet 19; an output terminal C and an output terminal D for connection with a load 30a; an electronic open/close switch 15 that is inserted in a direct current circuit between the input terminal A and the input terminal B, and, the output terminal C and the output terminal D through which direct current flows, so as to open or close the direct current circuit; a parallel mechanical open/close switch 16 connected in parallel with respect to the electronic open/close switch 15; and a switch control circuit 14 for controlling an open/close time difference between the parallel mechanical open/close switch 16 and the electronic open/close switch 15. In closing the direct current circuit, the switch control circuit 14 is configured to close the parallel mechanical open/close switch 16 after the input terminal A and the input terminal B are connected to the outlet 19, and the electronic open/close switch 15 is closed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
