Description: Knobs are a great way to finish off your project and make it easier to adjust the level of your death ray. This knob mates to a 0.25" shaft. The knob slides onto the potentiometer and holds tightly with a strong friction fit.

The main body of these knobs is metal with a plastic insert. The outside is knurled for precise adjustment.

Dimensions:

  • 14mm high
  • 24mm diameter

  • \m/ BLACK METAL!!! \m/

  • Nicely made, however the hole is too small to accept a true .25" shaft. It is a good (tight) fit with the ~6mm shaft on the Rotary Encoder (COM-09117) shown below.

  • I wish there was a favorites or wish-list like section here at SparkFun to save things like this cool knob in for future purchase. I don’t need any any at the moment, but don’t want to forget about them ether… :)
    (EDIT) Added to my wish list! hehehe

  • I like the llok and feel of this knob, but I’m wondering if there are any available anywhere that dont have the position indicator line, and still fit the COM-09117 Rotary Encoder. If there are, where could I get one?

  • Got some and Love Love Love them… Where can I get the same knob in say 12mm dia? I really like this knob and want it to have a baby brother for my projects.

  • Is there any simple hack that will fit these onto a 6.0 mm shaft?
    They’re awesome, but just all my parts are metric!

  • is this compatible with COM-09288?

  • I might whack a couple of these on my next order. They are nice :)

    • Yep. I have one on my desk right now, they’re pretty decent. Sure, it’s a metal shell with plastic inside, but they feel pretty good when mounted.
