In a pressure switch, a joint coupling holder is installed in a case of a housing through an opening, and a joint coupling, to which piping is connected, is connected to the joint coupling holder. The joint coupling holder includes a protective wall therein, which is arranged on a straight line with a detector that is accommodated inside the housing at a central portion of a through hole. In addition, a pressure fluid, which is introduced to the detector through a conduit of the joint coupling, flows in a bypassing manner through a pair of communication openings while averting the protective wall.
