Packaging & Delivery



Pressure switch,
1. Easy to use and install
2. Security and reliability
3. The authetication of VDE, UL, CE




Product Description


  • Adopting Eng. thread quick connector(copper flare connection) or brass tube welding fitting structure, flexibly setting, easy to use and no special need for mounting and fixing.
  • Plugging or wiring connection designed to customers' choice.
  • SPST connection, normal open or normal close structure to customers' choice.
  • Security and reliability by adopting fusion welding stainless steel industor and full air-tight connection.
  • Any pressure value within 3~667PSI(0.02Mpa~4.6Mpa) can be made base on customers' requipment.
  • Pre-set pressure parameter before delivery allows direct use without resetting on the customers'site.



Working Principle:

when the medium(liquid or gas) pressure within the pressure system is above or below the rated security pressure, the dish metal diaphragm within the system jumps instantaneously, thus to push the switch contact to be connected or disconnected through a connecting rod; when the pressure drops to the rated recovery value, the dish metal diaphragm is instantaneously reset and the switch is automatically reset.



  • Measurement range: 3-667PSI(0.02-4.6Mpa)
  • Multiple pressure ports
  • CE certificated                                              
  • One group switch quantity output control
  • Intrinsic safety explosion-proof type
  • Conform to the state explosion protection standards
  • Flexibly installed and easily used,with no special installation and fixing mode.
  • Insert and wire-type electrical connectors can be selected 


  •  High or low pressure control and controlson household,commercial
  •  On air compressor to protect and control high or low pressure
  •  Hydraulic and pneumatic control system,various equipment and tools
  •  Petroleum, chemical industry, metallurgy, electricity, hydrology process at the sene
