Illuminated Toggle switch contacts? slightly confused..

[munice]

Hey everybody, I'm thinking about running some fog lights and some extra rear lights and was planning on doing a nice setup with a couple of toggle switches (no AC so i have a little spare dash space) I also thought it'd be nice to get rid of the pull out headlight/park light switch and replace it with one or two toggle switches. I thought itd be cool to use some illuminated switches that i have lying around but im a bit confused on how they work and which terminals are for what. the toggles have 4 terminals on them: two have copper rivets one has a silver rivet and one has a black rivet, i figured this hot neutral and ground but im still a bit confused. And lastly ive also got some switches marked for 24 volts, its that saying they require 12 v to illuminate or that they are rated to handle up to 24v? I do tinker with electronics here and there but ive never fully understood all the different configurations of switches.. any help would be appreciated!
