Mechanical Pressure Switch – Huba 605 Series


  • Fitting of the switch; Fast mounting with snap bracket system
  • Adjusting security
  • High contact strength (typically 10 cN); Essentially less susceptibility to polution of contact
  • Diaphragm design / material; Better long term stability achieved though the use of a 2 component silicon diaphragm; Unique trapezoid diaphragm design provides for a better contact release and therefore a more accurate switching point
  • Roll operation of contact surface; Less sensitive to contact polution through self cleaning effect

OEM Relative and differential pressure switch

Type 605 pressure switches are specially developed for use in gas fired heating systems. There are more than 40 million switches in use worldwide. Produced on a fully automated production line. High setting accuracy and reproducibility, combined with excellent reliability characterise a quality of switch above the industry norm.
