1. Each operator sub-assembly is available as a “-1” and a “-2” for 3-position selector switches. The internal cam of a “-1” is different from that of a “-2”. This results in designated combinations of open

and closed contacts in the various operator positions.

2. N/D = No circuit number designation required in assembled part number.

3. X = On (closed contacts) O = Off (open contacts). X-X Overlapping contacts remain on (closed) when switch is moved between these two positions.
