What is this float switch mainly used for?
This float switch is designed for automatic water level control in tanks, water towers, and reservoirs.
How does the float switch control the water level?
The float moves with the water level and triggers an internal switch to turn the pump ON or OFF automatically.
Can this float switch automatically fill a water tank?
Yes. It starts the pump when the water level is low and stops it when the tank is full.
Can it prevent the pump from running dry?
Yes. It shuts off the pump when the water level is too low, preventing dry running.
What voltage and current does it support?
It typically supports 250V with a current rating of 4A.
Can it directly control a water pump?
It can control small pumps (≤500W) directly. For larger pumps, a contactor is recommended.
Is it suitable for drinking water systems?
Yes, it is suitable for clean water systems if installed according to safety standards.
What liquids can this float switch be used in?
Suitable for water, oil, and weak acid/alkaline liquids. Not suitable for strong corrosive liquids.
Is it waterproof and suitable for outdoor use?
Yes, it is water-resistant and suitable for outdoor use, but avoid long-term extreme exposure.
What is the operating temperature range?
The typical operating temperature is 0°C to 70°C.
Is installation complicated?
No. Installation is simple—just fix the cable at the desired level.
Can the cable length be customized?
Yes. Common lengths include 2m, 3m, and 5m, and customization is available.
Is this product explosion-proof?
No, it is not explosion-proof and should not be used in hazardous environments.
What applications is this product best for?
Ideal for water tanks, rooftop tanks, water towers, household water systems, and irrigation systems.

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
