ABSTRACT OF THE DISCLOSURE This invention relates to an improved solenoid operated fluid control valve particularly adapted for use as a vacuum control switch in a motor vehicle. One aspect of this invention is the provision of a coil assembly adapted to be wound and terminated using completely automated processes. This feature is provided through the use of a bobbin structure having protruding coil winding posts which position the start and finish ends of the coil wire. Terminal members are installed onto the bobbin and have terminal contact portions which can be folded onto the wire. Another feature of this invention involves means for reducing noise generated from actuation of the valve device. In conventional solenoids employing a "C" frame member, direct mechanical contact exists between the "C" frame member and another component of the magnetic circuit of the solenoid. In accordance with this invention, a thin annular layer of encapsulation material is provided between bores of the "C" frame member and the associated components of the magnetic circuit. This layer of encapsulation material prevents direct mechanical coupling with the "C" frame component, thus reducing noise generation. Means for calibrating the valve assembly according to this invention are also provided comprising driving a pole piece member into the coil bobbin bore as electrical and fluid control signals are applied. The pole piece motion is stopped once a change in state of the valve is observed, whereupon the desired physical parameters of the valve are provided.
