DesignFlex-Pressure switches from WorldMagnetics

Mechanical pressure switches - PSF-Series

In many applications it is useful, to control pressure without complicated electronic and reliable. Pressure switches from WorldMagnetics are available in different (chooseable) port connections. They can switch low or high current. To use for pressure, differential pressure and vacuum. Pressure ports are selectable (see data sheet) and can be used for liquids as well. No supply required for device.

DesignFlex pressure switches

The small and lightweight DesignFlex pressure switches from World Magnetics are flexible in design and pressure range (pressure, vacuum, differential pressure). For applications in food industry or medical machines, these switches can be supplied made with FDA approved materials. Even chemical resistant materials are available, making this the perfect pressure switch for most applications. The cost effective design also makes the switch ideal for applications in consumer goods market. World Magnetics offer the patented PSF100A, which is  one of the few shock and vibration resistant pressure switch available world wide. The switches can be ordered in screened versions, too.

You require YOUR special pressure switch? - Please take contact with us, we will find it for your application.

On request you can have for all switches

 

  • Approval according internatioanl and military standards
  • UL-approval under E 41523
  • FDA approved materials
