I'm trying to find a toggle switch that can have 3 modes, so that I can have it toggle a fan from 5v, 7v, and 12v. I was looking here but theres sooo many! I don't know which one I need.
 
Actually, unless I'm way off base, you can't do that with a toggle switch. Even DPDT (double pole, double throw) switches only have an off-on1-on2 position selection, if memory serves. Of course, I'm going off of knowhow I learned some 25+ years ago, so it's very possible that I'm wrong. Anyone know?? :confused:

Something that might work better would be a rotary switch. Sorta like an old style tv channel changer switch (if you're not old enough to remember those, go visit a museum! :p ). This one has 6 throws (or positions), and should do the trick (I'm saying that by going off of an led fan I have, that says it pulls 130mA @ 12vDC.....this switch can handle 150mA @ 28vDC). More switch than you need, but at $5 + shipping, a good deal for you, I hope! :D
 
There are some toggles that are 3P3T. You might look in Digikey for some. http://www.digikey.com if you want just have them send you a catalog, its pretty thick too. You can also use the online search.
