What's the name of this type of switch?

what's the name of the type of switch then works by rotating it, and you can keep rotating it on one direction.  Like the kind of switch that controls the volume in a car.  I'm assuming that every click switches between being it conducting and not conducting?  I need to use one with a micro controller (I don't want to use a potentiometer because they can only rotate so much) and I need to know the name so i can buy one.

.  I think what you are talking about is called an "incremental rotary encoder".
this switch is also mentioned in some appliances as " JOG DIAL "  (such as mobile phones , media players and dj consoles )

If you have an old mouse you could disassemble that to get one, the scroll wheel in them uses the switch you describe....
