<P>PROBLEM TO BE SOLVED: To provide a downsized direct current outlet with small power loss. <P>SOLUTION: A direct current outlet comprises: an input terminal A and an input terminal B connected to a direct current power system 10; an output terminal C and an output terminal D detachable with a plug 19; an electronic open/close switch 15 that is inserted in a direct current circuit 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 plug 19 is connected to the output terminal C and the output terminal D, and the electronic open/close switch 15 is closed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
