Abstract:
1. A direct-current switch, comprising: 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; a serial mechanical open/close switch connected in series to the electronic open/close switch; a switch control circuit that controls the opening or closing time difference mutually among the parallel mechanical open/close switch, the electronic open/close switch, and the serial mechanical open/close switch; and a regenerative diode connected in parallel to the serial mechanical open/close switch so as to be reverse-biased, wherein when making the direct-current path a closed circuit, the switch control circuit: when making the direct-current path an open circuit, the switch control circuit:
