Vacuum switch with changeover switch Width across flats 19 Height 90mm Thread length 9mm Diameter 49 ADJUSTMENT RANGE [mbar] OVERPRESSURE SAFETY ORDER NUMBER PERMISSIBLE TEMP. SWITCHING ELEMENT Changeover contact SWITCHING FREQUENCY Body: Zinkdruckguss Connection: CuZn B Sealing element DIAPHRAGM Hydraulic oil, Machine oil, Heating oil, Nitrogen, sea water BRASS / ZINC DIE CAST A Kant vacuum switch Type 701 has an integrated electric change over switch. When a specific negative pressure is applied, a diaphragm is deformed. The deformation depends on an adjustable spring preload. When the switching point is reached, the diaphragm has undergone a defined movement which actuates the switch and opens or closes the electrical circuit. Specific pressure values can be monitored via the switching signal.
