Alpha Single-Gang 16mm Right-angle PC Mount - 50K Linear

This Alpha 50K Linear potentiometer is a two-in-one, good in a breadboard or with a panel. It's a fairly standard linear taper 50K ohm potentiometer. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a breadboard or perfboard.
