<p>There is provided a switching device or the like that is capable of efficiently performing operations such as the cutting off of a refrigerant and that 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 10 and 11 for individually stopping the flow of a refrigerant are provided in a plurality of pipes 6, 7, and others for making a refrigerant circulate between a heat source unit A and a plurality of indoor units C to E. The shut-off valves 10 and 11 are integrated into pairs. A number of pairs of the shut-off valves 10c to 10e and 11c to 11e corresponding to the number of indoor units are grouped together.</p> |
