Float Switches

There are several types of float switches and different applications for these switches. Some switches may be used for several applications, while others are only for a specific duty. Float switches may be used for pilot duty, to operate control devices such as relays and contactors, thereby never seeing a significant electrical load, or direct duty when carrying a full motor load. Float switches are manufactured to handle light to heavy electrical current in a normally open or normally closed application. Some are narrow angle while others are wide-angle. The higher amp wide-angle float switches are called motor rated, differential, or sometimes piggyback switches when they are manufactured with a special plug on the end.
