Abstract (en)
[origin: EP0954000A2] The pressure switch has a pressure chamber (50) receiving a piston (46) which cooperates with an electrical switch (60) that has a switch mechanism (62). The mechanism is operated when a given pressure threshold is reached, and provides a relative movement between the switch contacts (94,98,100) parallel to the contact surfaces, for cleaning the surfaces.
