CONSTRUCTION DETAILS OF
4 x 4.5 mm GKG MODELS
Model GKG __ __ __ 27 Shown
  • Special drive assembly (A) with pointed spring fingers to engage rotor upper surface contour. Spring fingers also provide proper tension for smooth torque and low resistance.

  • Special rotor (B) with die-formed "drive" contour on upper surface.

  • Flat-lapped and lubricated surfaces (C) join for reliable capacitance settings.

  • Special ceramic stator insert (D) with metalized electrode.

  • Solid one-piece housing (E) with integrally molded terminals and contact areas. Central tubular column is spun-out into a flare after assembly to maintain built-in spring tension.
