I am needing to put a transformer on a line for some 12V AC light.  My question is:  Would you place the transformer on the panel on the hot side of the switch or after the switch so the transformer is not "hot" all the time?

Thanks,
Danny

Personally, I feel you would be better wiring it after the switch at the panel so that the circuit is on only when switched. Certainly seems a safer way to me. Consider that you should probably fuse the primary & secondary of the transformer as well, depending on your load and type of transformer chosen.

If convenient you should switch the primary.  Otherwise it is fine to switch on the load side.  You need only to fuse one side of the transformer and again the primary is preferable.  Keep in mind that if you wish to limit secondary side current to, say, 10 Amps and you have a 10:1 step down transformer your primary side fuse would be 1 Amp.
