Hi
I want to know what is the difference between switches and circuit breakers in a PCB circuit, in my research I found that breakers have a rating voltage and a rating current but switches have only rating voltages, does that mean that a switcher can work with any value of current ?

Circuit breakers open circuit at a certain rated current and may or may not be re-settable.
By switch do you mean just a means of physical contact open/closing, as this is normally all they are.

I guess technically, although a fuse is a 'Re-settable by replacement' ' Circuit Breaker' when were talking a comparison to switches, semantics I guess.;)
