Hi,
I bought a potentiometer (the one at the left in the picture) recently. I found that it has two extra legs (as I indicated by the red arrows) which differs from the potentiometers I normally used (the one at the right in the picture which does not have these two legs).
Can anyone tell me what's the purpose of these two extra legs ?
Thank you very much !
