Thanks guys, I think I have it now. I CAN use the switch should I need or choose to.
Grigg - I have saved the instructions, thank you for posting them.
Gord wondered about my reasons for wanting to know. There are three - curiosity, redundancy & choice. I'm going to keep the 7 wire switch, there is nothing wrong with it and it is not fair to the seller to return it because I changed my mind. Now I know I can use it, I may decide to use it on this project. As Grigg pointed out, it gives more choices.
