Hi.  I have four or five small treble boosters made on vero which are just sitting on a shelf, unboxed and unloved.  There are also a few other similar circuits that I intend to build. 

I was thinking of sticking them all in one enclosure and using a rotary switch to select between them.  I have a nice big enclosure to house them in.

So this has led to a couple of questions:

1)   Are there any issues/pitfalls with sticking so many separate circuits in one enclosure?

2)   Am I ok using a single pole rotary switch, or should I use a 2 Pole switch and switch the signal and the power between effects?

I hope that makes sense?
To the extreme, I rock a mic like a vandal.

Use a 2-pole switch.  At this point, you'd either need to use a splitter to send the signal to each one in a manner that they inputs wouldn't interact, or else cross your fingers and hope they don't.  Easier just to treat them like independent FX, and use a 2P switch to true-bypass all the ones you're NOT using.

The caveat to this is that they can't ALL fit in the same spoit, so some will be farther away from the switch than others, and you'll want to avoid having wires all over the place, leading to and from the rotary switch, just to make sure you don't pick up artifacts here and there.  I suppose if you can arrange to have the rotary switch in the middle, so that nothing is too far away, that might be helpful.

Note that a nice chickenhead pointer knob for the rotary switch nicely sidesteps needing to have a 3rd switch-pole to activate a status LED.

Finally, some rotary switches include a little specialized washer that lets you select fewer than the maximum number of switch settings.  For example, this one - http://www.taydaelectronics.com/electromechanical/switches-key-pad/rotary-switch/rotary-switch-2-pole-6-positions-alpha-sr2611f.html - is a 2P6T rotary, but can be set to be a 2P5T or 4T type by moving the washer over a notch or two.
