Patent ID: 7663496

Claim:
A pressure switch having a detector therein for detecting a pressure of a pressure fluid, and outputting an output signal on the basis of a pressure value detected by said detector, the pressure switch comprising: a housing made of a resin material and accommodating said detector therein; a joint coupling having a passage therein through which said pressure fluid flows, and which is connected to piping through which said pressure fluid is supplied; a connecting member made of a resin material, which connects said housing and said joint coupling; and a connecting mechanism for connecting said connecting member with respect to said housing, having one or more pawls, which are formed so as to be tiltable in a radial direction on an end of said connecting member and which engage with an opening of said housing, and a stopper that regulates radial inward displacement of said pawls, wherein said stopper is formed in a cylindrical shape, and said connecting member is held with respect to said housing through said pawls, as a result of regulating the displacement of said pawls, which are engaged with said opening, by said stopper.
