Hi, I'm Mike G and I'll be assisting you. Unfortunately you won't be able to originate the single pole switch off the 3 way wiring. You'll need a hot and neutral from another source. Your 3 way only provides hots depending on the position of the lead switch and no neutral.

I'm using a combination 3-way/ single pole switch. Won't the hot to the single pole come from the hot part of the 3-way?
Expert:  Mike G. replied 1 year ago.

No, the hots at that switch are onlyhot depending on the position of the lead switch. They alternate, that's how a 3 way works.

Customer: replied 1 year ago.
Then what's the purpose of a combination switch? It has instructions for using a single hot or two separate hots. For two hots you break off the tab in the middle of the switch.
Expert:  Mike G. replied 1 year ago.

They are used where the 120V feed powers both switch's, not on the second 3 way location.

Customer: replied 1 year ago.
But I do see that their diagram has the hot going directly to the switch.
Expert:  Mike G. replied 1 year ago.

Yes that is in the lead box not the location of the second 3 way box.

OK thanks.
