Magnetic Reed Switch Technology and Protection
Magnetic reed switch operation is simple but reliable. The float moves a sealed permanent magnet along the stem as the fluid rises and falls. As the magnets pass over the switch, the reeds are pulled together to create a highly reliable contact.

Specific Gravity
Specific Gravity (SG) is the ratio of the object's density to that of water. Since water has a specific gravity of 1 at sea level, liquids and substances with a specific gravity lower than 1 will float in water. Therefore it is important to select the proper float switch and float for your application.
