Present conditions (shop electrical, all recently installed by certified
electrician):

I have a 220V/1phase 20A per leg circuit going to a small davit crane
mounted 

on the top if my office, inside my shop.  Used occasionally to lift light
loads for storage.

Desire:  convert an adjacent 110V 15A quadplex outlets box to one duplex
outlet 

remaining 15A while splitting the remaining duplex outlet to 2ea outlets,
20A each. 

In other words, splitting power off the 220V/20A circuit into 2 individual
outlets, 

110V/20A (utilizing sides A and B from the 220V source).

Here's the other situation, I want to insert a rotary switch A-OFF-B to
switch between 

Using ONLY the 220V circuit OR the 110V circuits.

Anyone have recommendations as to a recommended rotary chang over switch?

Does this make sense?  I'm sorry I'm not familiar with the correct
terminology here, but 

I hope I'm making some sense.

I understand what you want to do. I have no idea why you want to.   Assuming=
 you have a three wire (plus ground, but I=E2=80=99ll ignore ground) circuit=
 to your crqne, you simply extend it to your other box. Break the tab on the=
 hot side of the outlet, land one leg to each hot screw, neutral to the othe=
r side.  Done. The breaker will take care of overload, it will trip both leg=
s, even if only one is overloaded.=20

Th=C3=A9 problem you are likely to have is you have no neutral at your crane=
, because most motor loads don=E2=80=99t need one.  If you have conduit, add=
ing one is possible and maybe easy. If you don=E2=80=99t, you need to pull a=
 new circuit.  In that cas probably don=E2=80=99t need to share with the cra=
ne.=20
