Let’s introduce a negation of value NOT operator is common for total object, not for separated values of object.

        Exactly with this image we defined an object of filtration. But, what should return one object of filtration like this?
        We are interested for one of its interior state (from 9/7 possible states); it is string value of momentary state of filter.

Beautifying of the object image                              
We want to simplify (maybe to set) one object’s image. Instead of arrows, we can place words “low” and “high”.
These words have greater importance than arrows. If you don’t like these words or you maybe have an idea for
something else, be free to change them (those are not official words). We do this in order to get more space for working part of object.

But, with which object we can operate? To identify it in a mass of other objects, we will add some description, title or address.

Yet, we can recognize our object. Add to our switches a power of real switches.
