I've never seen this type of dial, so I thought this might be very useful when one needs to return a potentiometer back to an exact value.

I got it from eBay, from a seller called: delhanway2009

Product links change all the time, so if you want one, just search with these keywords: Scientific 10K Ohm 3590S-2-103L Count Rotary Wirewound Potentiometer Pot 10 Turn

    I’m adding these to my laser! I needed to understand better what they are. Thank you!
  • This would be amazing for adjusting the negative feedback on a tube guitar amp. And a high school locker knob to boot!

    I have an old Beckman "Helipot" from the 50's with this kind of dial. It has 15 turns, but it's otherwise a lot similar. A bit bigger and more solid though.
  • I just got an analog oscilloscope that has one of these. Pretty nifty.
  • Hi Thanks for the useful video👌 I want to use the micrometer limit switch that is applicable to the hydraulic hose crimping machine, and it uses Vishay Turn Dial Please help if it is possible for you
  • Hi, I just bought two bourns one.When I measured ohm via multimeter it works perfect. Then I added with my arduino board but it did not work. Then I again tested via multimeter but it is not showing any resistance. Do you have any idea why??
  • How does the multi turn work differently compared to a single turn potentiometer. How does it keep changing the resistance for multiple turns?

    Why not show how to wire it for those that do not know?
