Surprisingly
compact, the Series L6 Flotect® Level Switch
is designed and built for years of trouble-free service
in a wide variety of process liquid level applications.
Operation is simple and dependable with no mechanical linkage
as the level switch is magnetically actuated. The float
lever pivoted within the body moves when the process liquid
displaces the float. A magnet on the opposite end of the
float lever controls a second magnet on the switch actuating
lever located in the switch housing.
