a potentiometer with an on/off switch?

Hi, I am new to Arduino and electronics in general. I'm looking for an electronic component that can work as both a potentiometer and an on/off switch. Like those volume controls you find on older stereo equipment where you turn the volume knob all the way to the left and it clicks off. Is there a name for this? Can you recommend where to buy one? I've searched SparkFun, but it's tough when I don't know what it's called.

Thanks in advance for your help.

Sounds like you are looking for a rotary potentiometer switch such as: http://www.bourns.com/pdfs/0503.pdf

I think that’s it! Thanks!

NP glad I could help!

One of my favorite surplus dealers has some with both push-pull and rotary switches. At surplus prices :)

Note that pots with rotary switches are most commonly audio taper, rather than linear. If you're going to use it as an input to the Arduino, you usually want linear.
