3 position switch to control 3 things

I would like to wire a single 3 position switch, preferably toggle or rocker, in that order, to control three items.

I beleive I need an on/on/on switch and 2 relays. Items are  A, B, and C.

Position 1 would  = A,B,C ON

Position 2 would = A,C ON,  B OFF with no loss of power (even momentarily) to A & C while moving to position 2 from position 1

Position 3 would = A,C OFF, B ON

I may need to use a make before break switch (shorting) but am not certain of that.

I have tried "connecting the dots" on this unfinished schematic... and I cannot figure it out...  Can anybody help?

Here's the schematic:

Thanks for any help...

Here's what I think might work... but I might be getting answers in the relay section...  I'm sorry for the confused posting.

This is my attempt:
