A switching device or the like efficiently performs operations such as the cutting off of a refrigerant and is easy to maintain, design, and manufacture at low cost even if the switching device is included in, for example, an air-conditioning apparatus including a plurality of indoor units. A plurality of shut-off valves for individually stopping the flow of a refrigerant are provided in a plurality of pipes for making a refrigerant circulate between a heat source unit and a plurality of indoor units. The shut-off valves are integrated into pairs. A number of pairs of the shut-off valves corresponding to the number of indoor units are grouped together.
