Displacer level switches are level indicators that use the technology of buoyancy to detect liquid levels. A spring is loaded with weighted displacers that are heavier than the liquid. The displacers are immersed into the liquid which causes buoyancy force to change the net force on the spring. This causes the spring to compress. When the spring compresses, a magnetic sleeve compresses, and actuates a switch mechanism. This causes the switch to turn on or off, depending on the programming.
