Default DPDT ON/ON for A/B switch?

Am I correct in assuming that a DPDT on/on switch is needed for the A/B switch and all (RCA) jacks get a common ground?

Yes, common ground is normal for 99.9% of gear.

OK..... progress is slow due to summer activities, etc

I have one dumb question.

The wire that I used for grounds is a bit of overkill but it was all I had on hand at the time and..... it laid neatly on the bottom of the case.

However, the wiring to the to the DP/DT switch and RCA center pins need a lighter gauge wire of course for obvious reasons.
My dumb question is.....will the 24 gauge wire used in CAT5 cable be adequate?

BTW it just A/B switch to be used from my phono pre..... to either straight to my amp or through my resistive stereo to mono mixer first.

24 gauge, so that's around 0.5mm. Everyone has there own ideas on wire but yes, its fine. There is no current flow involved (only micro to a milliamp or so).

Thanks.

Actually, I just came from the local Radio Shack where I got some small spools of 22 gauge copper hookup wire ....in 3 different colors.
So, I no longer have to scrounge around for suitable wire every time I need it .

For small amounts of smaller wire in various colors, you can often steal the wire harness out of some dead piece of gear. Sometimes I strip down an old VCR or cassette deck to the last little screw, just as calming therapy. many times they have a variety of colored wires. Old TV, whatever.
