Abstract

A miniaturized direct-current switch with which power loss is reduced when establishing continuity of a direct-current path is provided. A direct-current switch includes an electronic open/close switch 15 inserted in a direct-current path along which a direct current flows in order to make the direct-current path an open circuit or a closed circuit, a parallel mechanical open/close switch 16 connected in parallel to the electronic open/close switch, and a switch control circuit 14 that controls the opening or closing time difference mutually between the parallel mechanical open/close switch 16 and the electronic open/close switch 15, wherein the switch control circuit 14 makes the parallel mechanical open/close switch 16 a closed circuit a predetermined time after the electronic open/close switch 15 has been made a closed circuit.
