This extremely compact vacuum switch gives an electric signal when a certain adjustable level of vacuum is reached.
The pressure differential existing between the set maximum value and the value of reset of the rest signal is 50- 60 mbar and it is not adjustable.
They are particularly suited when an electrical signal is needed when a certain level of vacuum is reached, for safety, for starting a cycle, for checking the cup grip, etc.
