Hi, all, and especially Joerg,
My beautiful layout hunchback is laying out the boxcar lock-in board. It contains a current source to drive the LED, which has a trim pot.
Normally over here, they're marked "CW" and "CCW" so you know which end is which.
In the Eagle library, the ends are marked "A" and "E", and the wiper is "S".
Anybody know which of the ends is CCW?
Thanks
Phil Hobbs

I have a schematic in which potentiometers are used with this symbol. They are volume controls in an audio circuit and the "A" is connected to GND. See partial schematic below. The original was made using Eagle.
