  The switch is designed so to open a three-pole electric circuit when the pressure in the system rises and to close it when the pressure decreases.
Designed for electric boilers of coffee machines as main application.
In conformity with EU Directive 2002/95/EC (RoHS Directive)
TECHNICAL FEATURES  
  • Cover in glass fibre reinforced PBT (Polybutylene-terephtalate).
  • A diaphragm in PTFE (polytetrafluoroethylene) backed by a diaphragm in FPM (fluoro-carbon elastomer) is the sensing element wetted by the medium.
  • It can withstand overpressures up to 2.1 bar.
  • Snap action switch is vibration resistant type.
  • Silver contacts with double break for each phase
  • Diaphragm housing in forged brass with pressure intake for bi-conical connection.
  • The pressure switch can be adjusted at will at pressure value P included in the range: in this way the opening pressure is set.
  • The Dp value is pre-fixed and understood as the differential of the pressure switch.
