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.
