Technical foreword of elastomeric membrane pressure switches

The pressure switches of this catalogue are made according to the flexible elastomeric membrane technology. The pressure applied deforms the membrane which then actuates an electrical contact.
Differences between air switches and pressure switches

Differences between air switches and pressure switches

Pressure switches are used to control the pressure of a medium and operate an electrical device. When pressure rises to the set point value, they switch off the equipment or switch on an alarm. Fluid they control can be air or water. There is no barometric...

Although pressure is an absolute value, the current measures pressure, are usually made relative to ambient air pressure. In other cases, the measurements are compared to vacuum. This leads to confusion and errors.
