Hey folks,

We started using some Bourns dual concentric PTH potentiometers for a project.
And even though they're a very well-made and useful pot we discovered that NO ONE sells knobs for these pots.
So we had some made! Right here in the USA. And we figured it would help everyone out if we offered some up for sale.

They fit very nicely. Two set screws (1/16" hex) )on the bottom portion and a good snug fit on top.
Brass insert. Classic simple styling. High quality American made knobs.

NOTE: this is just for the knobs. You can buy the dual concentric potentiometers at Mouser. And please check the pdf there as well for added info.
These are made for flatted-D 30mm shaft.

More details:

First the push on top -

OD 0.5"
Height: 0.48" or 31/64

Now the bottom -
OD 0.7" or 45/64
OD w/ standout indicator 0.81" or 13/16
Height 0.73" or 47/64

And the top does nest down somewhat in the bottom piece.
Pushed tight together they're roughly 1-1/8" tall but applied to the bourns pot there is a variable amount of separation between them to allow for rotation and also depending on the exact application of the lower section.


Need more than one? Just let us know and we'll give you a deal based on the quantity.
Price is for the set, top and bottom.

Thanks,
The Team at Avion Studios
