The Role of Vacuum Switches


Lefoo is recognized worldwide for the quality of its product line. From vacuum switches, pressure switches, reverse osmosis pumps, among others, the quality found in each item is a guarantee of confidence in the entire system. Among this wide range of products, Lefoo operates with vacuum switches designed for various industry applications.


A Vacuum switch is defined as a negative pressure switch (vacuum / below atmospheric pressure). Acting as an electrical switch at a predetermined negative pressure. Basically, a vacuum switch acts to open or close an electrical contact, with the function of signaling when a certain negative pressure is reached.


As in the case of pressure switches, the accuracy of vacuum switches is extremely important, since these components are responsible for the activation of other components and equipment. Minor flaws in these components can cause serious problems, from losses in productivity to the compromise of the entire safety of an environment, in more complex applications.


Lefoo works with customers around the world to develop more accurate vacuum switches, serving from generic to more specific applications.
