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.
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?
