I don't usually use input switches but need to fit some on a project preamp.
In favour of toggles: greater force on contacts
In favour of rotary: less crosstalkwhich type, contact material and makes would you use for best sound?
My inputs are balanced, so I need 4 pole. I could use separate right and left if such a DPDT toggle was very much superior. Thanks, Andy

Hi Andy ,
If switch quality is the prime concern , use the switch for muting the input and swap cables ;)cheers
I use hermetically sealed mil spec 4pdt relays mounted right by the XLR connectors. Keeps the signal chain shorter and less chance of crosstalk and hum pick up etc. Then I use a rotary switch to control the relays and indicator lights on the front panel. I got the relays dirt cheap off Fleabay and the silver plate ceramic rotary from Nebraska Surplus Sales.Dave
...if both channels are switched by the same switch then each channel ought to be separated on separate wafers. The subminiature toggle switches contacts are too close together and cause cross talk. Toggles are ok for power All just IMHO.

Hey, Andy,Also in favor of rotaries; wiping action of contact, which I think may be the biggie.
I use both. The Toggle I use is the E-Switch silver contact from Digi-Key. They're hermetically sealed (for wave soldering probably), so the silver will stay nice, but you're limited to two inputs. The Digi-Key part number is EG2417-ND; this with the long handle and center off, so you have a mute. The rotary I use is the Swiss Elma; I can't hear any difference, but I bet somebody will respond calling me a cloth ear.
Aloha,
Poinz
