Hi all,

I have a simple question I am sure for you guys, but I am merely an idiot when it comes to these things and most other things too. :) Anyway,

I am looking for a momentary key switch (just a lame project) that can handle at least. 2 AMPS in 12 volt DC. For example, I see switches that can do 4 amps at 120 volt and that very same switch the specs state 2 amps at 220 volt. etc. How is that possible? Aren't amps, amps?

Is it safe to assume if a switch is rated at 4 amps 120 volt AC, it will still handle or work well with say 12 volt power source in DC?

How exactly does amps work in DC? Thank you!
