Web21 de abr. de 2015 · Normally open switches have an open, or incomplete, circuit when the float is in the “normal” position. The “normal” position in most cases will mean that the float is suspended above the liquid line, not floating. When the liquid level rises, the float moves with it, bringing the magnets up and into a position where they attract and ...
