How is the operation of a float switch controlled?
What will be an ideal response?
The operation of a float switch is controlled by the upward or downward movement of a float placed in a water tank. The float movement causes a rod-operated or chain and counterweight assembly to open or close electrical contacts. The float switch contacts may be either normally open or normally closed and may not be submerged. Float switches may be connected to a pump motor for tank or sump pumping operations or tank filling, depending on the contact arrangement.
