| Zusammenfassung: | An electric-supply-switch relay-circuit includes a first switch unit for passing an input current from an electric-supply line as a relay operating current; a relay for performing switching operations in accordance with the relay operating current; and a current detect control unit for detecting the input current. When the input current is found to be equal to or larger than a predetermined value necessary for operating the relay, the current detect control unit turns on the first switch unit to thereby allow the input current to the relay. |
