Further product information
When using 2 float switches, one working as a maximum contactor and the other as a minimum contactor, you achieve
automatic level control. In addition, the float switch can be used as overflow and dry run protection. The float of the QFS-55 float switch combination is made of Teflon. Inside the float, one or two reed contacts with a movable permanent magnet are inserted as switching element. The design of the switching element is such that even a slight displacement of the switching element from the horizontal triggers the switching operation.
