Float Switch, Top Inserted, Single Point. The Delta Controls Model 709 Float Switch is a simple mechanical device which is highly reliable over long periods of time. An alarm switch-type action is provided as the liquid level surface passes through the elevation where the sensing float has been positioned. The sensing float is attached to a vertical shaft, which can move up and down. Lifting the float causes the output switch station to activate. The switch station is on the outside of a solid, non-magnetic pipe wall. This isolation eliminates the possibility of leaking seals and flex tube failures, which are problems in many other designs.
