V. Operation
a. The WA150 Tilt Float Switch's basic operating principle is that as the fluid
level rises the rubber float will rise, causing the micro-switch to tilt and
generate a signal that can be used to operate a motor starter, open or
close a valve or actuate indicator alarms as required. The Tilt Float
Switch's three-conductor cable allows operation on increasing level or
decreasing level. One lead is common, one is normally open (NO), the
other is normally closed (NC).
