I'm looking for an electrical coupling to provide 120VAC

only turn one way, so it can't have wires up the hub.
Is there a commercial product out there, and if so, what
is it called? None of the electrical places I talked to
knew of anything like this...
It's called a slip ring, sometimes called a commutator ring (a commutator
ring is a specialized type of slip ring.)
