According to a connection switching method of a switch for selectively setting a connection path between a plurality of input lines and a plurality of output lines, the types of faults which may occur on the input lines are defined. Connection destination information indicating connection states of the switch are stored in accordance with the types of faults. The type of fault is specified on the basis of the defined types of faults when a fault occurs on an input line. Connection destination information corresponding to the specified type of fault is read out. The connection state of the switch is switched on the basis of the readout connection destination information. A connection switching apparatus is also disclosed.
