This potentiometer is a two-in-onegood in a breadboard or with a panel. Its a fairly standard linear taper 10K ohm potentiometerwith a grippy shaft. Its smooth and easy to turnbut not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-pointsso you can plug it into a breadboard or perfboard. Once you\'re done prototypingyou can drill a hole into your project box and mount the potentiometer that way.
