Tilt Float Switch, Norm Open/Closed, 49.2' L, Polypropylene, M4189 Series
The M4189 Series tilt float switch provides efficient and highly reliable level detection in open vessels, sumps and ponds.
The molded plastic float has an integral three-conductor cable which is connected to an SPDT micro-switch that is sealed inside the float. As the float rises or falls 30° to 45° about a horizontal location where the cable is anchored, the switch changes state from normally open or normally closed as the float swings up and down.
