Spring-type terminals are new types of spring-type terminals, which have been widely used in the world's electrical and electronic engineering industries: lighting, elevator control, instrumentation, power, chemistry, and automotive power.
If the terminal block is black, one of the possibilities is not necessarily burning black, oxidation may also be black. So how to verify whether it is burnt black? The method we take is to wipe it with a finger. If it can be wiped off, like soot, it is the black substance formed by oxidation, which can only be ground off with sandpaper or a file.
