A magnetic float or counterweight actuates a microswitch in the unit without contact.
When the float or counterweight passes the bistable switch, the toggle switch changes its position and remains in this position until it is passed again. The switch works with all floats and counterweights available from us.
It is designed for mounting on string level indicators type Stringline SFA..., sight glass level indicators type GNR5 / KNR or overhang level indicators type FS4.
