Vacuum Switches

Vacuum switches ensure the safe operation of a vacuum circuit. In the mechanical version, the vacuum is measured via a membrane. A microswitch or valve is then activated. With the electronic design, the existing vacuum is measured via a sensor and issues an analog or digital switching signal.


  • Mechanical vacuum switch for process monitoring.
  • Optimisation of cycle times or regulation circuits.
  • Application in processes where an electric or pneumatic signal related to a defined vacuum value is required.
  • Can be used as a measuring and switching element.
  • Design

  • Vacuum switch in electro-mechanical (EM) and pneumatic (PM) version.
  • VS-V-EM-ST with one digital switching output in NO/NC version.
  • VS-V-PM with pneumatic output in NO or alternatively NC version.
  • Robust and hard-wearing plastic housing.
  • Cover (1) for IP-protection and strain relief of the connection cable (optional for EM version).
  • Cover (2) for IP-protection and mounted M8 4-pin plug (optional for EM version).
  • 2 m cable (3) with M8 plug, 4-pin (optional for EM version).
