Frequently asked questions
Will this knob fit my potentiometer?
It is designed for a 6 mm shaft hole. Measure your potentiometer shaft diameter and check whether it is round or D-shaped before mounting, since the fit depends on it.
How do I mark the scale on the knob?
Use a fine pen or marker to draw the position marks on the dial face, then read the setting against the panel markings as you turn the knob.
