NO! NO! NO!
The neutral is NEVER connected to a (non-X-10) switch!!! (Again, except for switches that contain lights, etc.)
One of the wires that hits the switch is constantly hot, and the other is the switched hot, or 'return leg'. The neutral is connected directly to the load. All of the switching is done in the hot wire.
As for colors, normally, any wire that is white is assumed to be the neutral, with the following exceptions:
When a 220v. load (such as a water heater) which does not need a neutral is fed using a cable (black, white, bare), the white can be used as a hot wire, but should be re-colored non-white, with tape, paint, premanent marker, etc.
(A 220v. load that
does need a neutral (such as a dryer), there will be a red (or another black, or anything other than white) wire to be used as the second hot wire, freeing the white to be used as the neutral)
When a single cable is used to feed a switch, (where the wiring is run to the load first), the white wire will be the one feeding the switch, and the black used as the return leg. (This is done so there will not be two white wires attached to the load). The white wire does not have to be re-colored here)
These exceptions are allowed because cables are always manufactured with one white wire. Of course, with conduit, where you can pick the colors you use, white will
only be used as the neutral, no exceptions.
If there is a neutral already in the switch box, there will be two (or more) white wires connected to each other, but no whites to the switch. This is the neutral you're looking for.
If there is not, then you will have to run a new cable to the switch box from another box somewhere
on the same circuit! Use a whole cable, not a single wire, even if you won't be using the black for anything.
