If this switch says it's rated for 12V 20A does that mean it will work with everything UP TO 20 amps or that it has to be exactly 20 amps?

http://a.co/d/d1u8TdT

The thing I'm using is 5 amps. Is this okay?

>it has to be exactly 20 amps

you know its sad when questions like this get asked on DIY because sommon sense doesnt tell you that when something is rated for a certain amperage it usually means not to EXCEED that an can be used for any amperage below the rated amperage

It's a basic question sure, but it's a valid question.
It's easy to see why someone would be unsure.

yes, the switch is ONLY for exactly 20 amps. at 19.99999999999999999999999999999999999999999999999999999999999999999999999999999 amps it blows up and at 20.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001 it blows up.

the idea that a switch only works or is only for a specific amperage is absurd, his question would only be relevent regarding fuses or circuit breakers.

Give the guy a break.

I know this is 4chan but fuck these elitists who have to spread misery just to get their weenies hard.

You missed the point anon. The basic understanding of volts, amps, and ohms isn't something an anon would intuitively know. A breaker rated for 12v 20a will work fine with a power draw of 5v 1a. An electric motor rated the same will not. Without a little education in the subject you'd never know why.

why do we hate the word so much? I say "current" like everyone else I know, but amperage is a proper synonym, isn't it?
