Flann’s range of precision manual and stepper motor controlled switches are now available with Ethernet power and control.

These switches can be embedded within a test and measurement system without affecting calibration because of their extremely high repeatability. This design is built on the hugely successful xx333 series, some of which have been operating 24 hours, 7 days a week for over 20 years.

They are available in ‘2 channel’ or ‘3 channel’ rotor configurations, to allow many different switching options.


  • Power and remote control over Ethernet
  • Models up to 330 GHz
  • High accuracy and repeatability
  • 2 or 3 channel rotor
  • High Isolation
