Re: Question about toggle switch
While I have dabbled with 120v wiring (I've wired up a couple production greenhouses for my wife's orchid raising passion and added a couple circuits to the house) I am by no means an electrician. That said, my initial concern would be that the switch is not rated for the amperage that would flow though it. Depending on the age of your house and the breaker panel in it, it could be seeing as much as 20 amps and that's an awful lot of sauce for a switch like that I would fear.
As for the actual wiring, it might be able to be done but I'd have to think on it a bit. In an AC circuit a SPST switch usually is just a "break" in the hot (Commonly black) wire and the common (Usually white) is wired around the switch itself. How you would simulate that with a switch like that would require some crafty wiring.
Again however, I am not an electrician and I could be wildly wrong. Still and all, I would make sure that switch is rated for a minimum of 120V and 20A.
