uxcell Plastic Straight Slide Potentiometer Flat Push Knob Insert Shaft 4x1mm Gray 10pcs

I didn't buy these to match any missing knobs on any control surface, I got them to pair with some sliding potentiometers (PTA6043-2015CPB103 - POTENTIOMETER SLIDE, 10KOHM, 250mW,) And they fit great, nice and snug quality all around. They are simple but I couldn't find much of an issue with them

Measurements are Exact!!! Fit perfectly in my Yamaha EMX

They fit and work well
