identification - What kind of knob fits a slotted potentiometer shaft?


What I thought was an easy question is more elusive than I suspected. I have a number of potentiometers that have smooth (not knurled) shafts with a slot cut into the end...it looks like a flathead screw.


similar to this, from Mouser's site


I need a knob for it, but can't find one. I suspect I don't know the right thing to ask for. When I google "knob slotted potentiometer" or similar, I get a ton of pots drowning out anything I might hit for noise, and no useful links if I search for "slotted knob" "knob for slotted" etc.


While a set screw would likely work I'd prefer to get something that's made for the shaft I'm working with. Does someone know what I'm looking for and what search terms I need to use to effectively filter out the pots from the knobs?

The slot is for adjustment with a flat-headed screwdriver (instead of a knob), and is not generally intended as a feature for the knob to engage with. Just use the same type of knob that you'd use with a purely cylindrical shaft - a knob with a setscrew:
