Further product information
The QFS-1. float switches can be supplied with an outer casing of polyethylene. Inside the float one or two reed contacts with a pivoted permanent magnet form the switching device. The switching device is so constructed that a slight shift of the switch from a horizontal position triggers off the signal. A highly flexible, three-core cable is used both for the electrical connection and for the mechanical attachment of the QFS. The whole QFS unit is so constructed that the float and the lead-in line are hermetically sealed.
