Pressure Control Device and Method of Making the Same Abstract A pressure responsive control device having a pres- sure housing assembly defining a pressure chamber, an actuable control fixed to the housing assembly and, a pressure transducer module hermetically closing the pressure chamber. The module includes a snap acting pressure responsive diaphragm, a diaphragm control plate hermetically bonded to the diaphragm outer periphery, and a support member hermetically joined to and support- ing the control plate and hermetically joined to the housing assembly. The control plate has a supporting region rigidly supporting the diaphragm and the diaphragm control regions are yielded and deformed relative to the supporting region to position the control regions for stressing the diaphragm to determine the chamber pressure levels at which the diaphragm moves.
