An adjustable lever mechanism and springs on a cascade switch are used to control the monitored medium's pressure at port pressure, depending on the pressure range. Flutter-free switching is ensured by this method. It doesn't matter where the switches are positioned because they're still going to work. Kontakte 1 and 2 are shut off if there's no pressure on them. Pumps and compressors may be turned on or off. Contact 1-2 opens and contact 1-4 shuts if the upper switching point is reached. Pumps and compressors will be turned off to save energy.It is only after the membrane pressure has decreased to the predetermined lower switching threshold that contact 1-2 will be reactivated. With a screwdriver, the upper and lower switching points can be individually modified.
