Control knobs GN 957 are used in connection with position indicators. These control knobs offer a simple solution when the assembly requires manual fine adjustment for the application for which it has been designed.

The design of this knob adapts it to the diameter of the adjustment shaft, so that no adapter bushings RB50, RB51, RB52 are needed.
