  • Pressure switch
    Patent number: 7893371
    Abstract: 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.

  • Pressure switch
    Patent number: 7663496
    Abstract: In a pressure switch, a joint coupling holder is mounted via an opening in a case constituting a housing. A plurality of engagement pawls that make up the joint coupling holder engages with a bottom of the case. Further, by inserting a cap into a recess of the joint coupling holder, the engaged state of the engagement pawls is maintained, whereby the housing, which is made from a resin material, and the joint coupling holder are strongly and rigidly connected together.
