If two points are required, two pressure switches with different calibrations should be employed. The method of fixing the tab terminals to the switch body does not allow for absolute air sealing. The switch is therefore not reccommended for applications where static vacuum has to be maintained. However, special models with additional pressure spring that allow for the vacuum to be connected to the pressure inlet side are available on request.
