I am considering making a switch box for 2 or 3 digital line sources with a line out to a DAC. I am thinking in terms of coaxial wires. I assume a regular rotary switch will do but i am unclear about handling the earth connection. Do I switch eart as well as line or do I connect to common earth in the box?
I would be very grateful for any advice.

Hej, Åke, thanks for the hint !
I will look into this. I see there are some items there that might suit my needs, such as this: 3 WAY PHONO RCA STEREO AUDIO INPUT SELECTOR SWITCH | eBay
My digital sources already have volume control. For digital signal I would only need one channel.

Thank you Frank!

10base-T networking is (was) classic 50R terminated BNC / coax, but I have never seen this switched as in a "1 of n" selector! Besides, that is VERY dead technology!
Video switches, however, can use coax center-wire switches - reeds are good and make keeping the 75R impedance within bounds very easy.
