Rotary knob without marker for 6-mm axis
The cross-cut collets in the knob body are pressed around the
full circumference of the potentiometer/switch nuts with a secure and non-slip fit by tightening
the hexagon nut. The shiny, conical knob body is roughly notched around the circumference for secure
operation. The collet chuck is sealed by the cover.
Please order cover separately!
