CF / DF Series
Please note that the index number positions for the CF / DF Series are the reverse of the index numbers for the U52-Series knobs we carry. 
Verify the switch is in the OFF position by turning the shaft to the left until it stops. To determine the correct index number, you need to know the direction of the ‘D’ flat on the switch shaft when it is mounted in relation to the panel markings. The index numbers shown represent the position of the ‘D’ flat on the switch when the pointer is at 12 o’clock. If the pointer needs to be facing any direction other than 12 o’clock, consider this:
Pos #1 – Pointer is facing opposite the ‘D’ flat
Pos #2 – Pointer is 90 degrees counter-clockwise from the ‘D’ flat
Pos #3 – Pointer is facing the ‘D’ flat
Pos #4 – Pointer is 90 degrees clockwise from the ‘D’ flat
