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).
