Good flip/rotary switch for 2 sources?

[Jockaruba]

Hi,
I want to make a simple passive preamp.
What would be a good quality switch to switch between 2 sources, DAC and Phono preamp?
I am looking for good but not the exotics
Thanks for the help

you could use a pair of signal relays.

One DPST relay for one channel and a separate DPST relay for the other channel. You could use DPDT and leave one contact empty.

You can even use a single DPDT relay to switch both channels. This may have slightly worse crosstalk.

I'd use a DPDT toggle switch with no center off, miniature with 3/8" round mount hole. Gold plate contact is important for analog line level signals. I have some cherry brand ones in stock but I can't quickly find any stock anywhere. (I checked newark). Watch out for gold flash; the US controls the minimum thickness of gold on jewelry described as gold plate, but other countries do not have a FTC to enforce this description nicety.

Thank you both
