A float switch is an electric device that controls the water levels in a well or tank. Connect a float switch by either mounting it on the wall or suspending it on a tank or well.
It moves up and down and triggers the closing or opening of the pump through circuit completion or breaking mechanism.
. All types can be effective depending on the installation and maintenance.
Components of a float Switch
- Switch System
- Magnet
- Float
- External Weight
- Float switch cable.
How does a float switch and Pump connection Work?
A float switch uses a float, magnet, switch, and weight to control the flow of water based on the change in water level. Float switches open and close depending on the water level.
Float switches contain magnets inside which move away or closer to the pump depending on the position of the float switch. When the magnet moves away from the switch the circuit breaks and the pump turn off thus the water pump stops.
When the magnet gets closer to the switch, the circuit is complete and current can pass through thus the pump starts to suction water.
To determine the float switch cable length, consider the specifications of the manufacturer since they contain maximum recommended length of operation.
How to Connect a Float Switch to a Submersible Pump
- Choose a suitable submersible pump depending on the requirements of your water needs.
- Connect all supply pipes.
- Choose a low point where you want the pump to switch off automatically when the water level reaches it.
- Choose the high point; Where you want the pump to start automatically when the float switch touches it.
- Mount the float switch on the wall.
- Adjust the weight of the float switch.
- Connect the float switch cable to the electric cable of the pump using a splicing kit.
- Conduct wiring from the electric pump cable to the control box using correct terminals.
- Lower the submersible pump and the float switch connection to the borehole.
Advantages of a float Switch
- They are long-lasting. Can operate for more than 10 years while still in good condition.
- They are reliable for fluid level control as they rarely fail.
- Can work in different fluids.
- Cheap and easier to install.
- Made of durable materials that are resistant to harsh weather conditions.
Applications of Float Switches
- They are applied in sump and sewage pump connections to prevent sewage water from rising above the pits.
- For control of pumps and valves in industrial and residential buildings.
- Drainage water pumping systems and slurry waste systems to protect pumps for dry running.
- Control of water and air conditioning in refrigerators. It switches on and off refrigerators depending on the temperature.
- Used in food industries to liquid flow in and out of storage points.
- Control of water levels in tanks and clean water supply systems.

Frequently Asked Questions
Float switches contain magnets inside which move away or closer to the pump depending on the position of the float switch. When the magnet moves away from the switch the circuit breaks and the pump turn off thus the water pump stops.
To control the water pump and prevent flooding and dry running of the pump.
The magnet inside the float switch moves closer or away from the switch depending on the water level.
