General Description

The switch can be used e. g. as minimum, maximum, filling, emptying contact as well as for protection against overflow or idle running. It can be installed directly in tanks using a screw joint or can be inserted into open tanks from the top. If inserted from the top, the switching point is determined by using a ballast weight. The float switch enclosure is made of robust plastic material. The micro switch is encapsulated completely water-tight. Moreover the unit consists of several air chambers.
Therefore it is almost unsinkable even if damaged mechanically.
