Default Audio selector switch

Hi everybody, I am looking in building an audio selector switch. I am planning to connect 2 or 3 turntables in one phono stage and have switches to select the different turntables.
Does anybody have a schematic for one?

Thank you

It could be as easy as a multi-pole rotary switch.

Or you could try the simple circuit I posted here. If you
want to switch the grounds also, you need a pair of DPDT
relays for each channel, instead of the single one I used.
