In the switch you describe, there are three positions with no "center off" and those would be listed as ON-ON-ON. In your description the switch could have 16 terminals. The three positions would connect first, rows 1 to 2, then second, rows 2 to 3 and finally rows 3 to 4 for each pole. I have seen switches that have one common row that connects to each of the three active rows, but those are rare and expensive, almost custom.

I wasn't explicit enough about my question. My question is why you would have more than three possible positions on this switch when the part description says three. Essentially, it just repeats the same on-on-on pattern four times for a total of twelve differnt positions and the number of positions that are available is adjustable by a stop. My best guess is that they just used the same design for all of their switches just to make it cheaper??? The switch
