The pressure switch (25 bar) opens and the cleaner stops. At the same time there is still high pressure between the regulation valve and the gun. The high pressure cleaner starts again when operating the gun.Micro switchesSpare partsPressure switchesDiaphragm pressure switches SW 27 Connector PG 9R+M Nr. start-up pressure912 515 blue 15 bar912 525 red 25 bar912 540 black 40 barContact 5 A - 250 V.
