Definitions

a further drawback is that the tappet assembly included in these prior pressure switches is usually welded at the central region of the membrane, which contributes to a further changing of the mechanic and resiliency properties of the membrane.
the used materials provided that they are compatible to the intended use, as well as the contingent size and shapes, can be any, according to requirements.
