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