摘要： In a feed line switching apparatus, a situation in which the feed line switching apparatus cannot work when feed lines have a predetermined connection relationship is prevented. The feed line switching apparatus includes a command acquisition unit which acquires a feed line switching command which designates a connection relationship of feed lines, a switching execution unit which switches the connection relationship of the feed lines in accordance with the feed line switching command acquired by the command acquisition unit, and a switching control unit which suppresses switching of the connection relationship of the feed lines in the switching execution unit for a predetermined feed line switching command.
