Normally open switching is obtained when the arrow on the mounting is pointed up, and vice versa, normally closed when the arrow is downward. FSVtypes Normally open or normally closed operation is selectable by inversion of the ofl at on the shaft. The switches are shipped normally open otherwise indicated. N.O. function, i.e. the contact opens when the liquid level drops. N.C. function, i.e. the contact opens when the liquid level rises. Specifications are subject to change without notice 2
