How do I determine whether a switch can handle the power/current …
It is not rated for audio at all. So you just have to try it out and see if it works. In general, lower frequencies are harder on a switch. DC is the hardest. Higher currents are hard on a switch. Higher voltages don''t necessarily put a lot more stress on a switch. Some switches have the same current rating at 120 as they do at 240.
How much voltage/current is "dangerous"?
Measure the 9V battery when on your toungue and you will find it is a lot less then 9V.

batteries
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
