About the CX-M15-4 float switch water level controller
The CX-M15-4 float switch water level controller is part of the ELEHPD FLOAT SWITCH range. Specifications - Simple Construction, reliable performance: - Sturdy and durable, need not maintain: - Easy to install and convenient to adjust: - Wide application range and strong generality Technical Data ELEHPD manufactures and exports low voltage electrical products from Yueqing, Zhejiang, China, supplying distributors, panel builders, M&E contractors and OEM buyers worldwide.
Typical applications
- Sump and sewage pits for automatic drainage pump control
- Water tanks, cisterns and storage reservoirs for fill and overflow control
- Boreholes, wells and irrigation reservoirs
- OEM water-treatment, dosing and cooling-tower packages
- Appliance and boiler level control where a simple on/off point is enough
How to specify the right FLOAT SWITCH
- Match the contact rating to the load: direct switching for small pumps, a contactor for larger or three-phase motors
- Pick the contact form and logic to the duty: NO to fill, NC to empty, so the pump fails safe
- Choose the mounting: cable pendant for sumps, side-mount for a fixed point, magnetic/rod for narrow tanks
- Confirm the float material and cable jacket against the medium and temperature (PP for water, oil-resistant for pits)

Frequently asked questions about the CX-M15-4 float switch water level controller
Can a float switch run a pump motor directly?
Only when the contact rating comfortably exceeds the motor inrush. A small single-phase pump up to the contact rating (for example 10(8) A at 250 V AC) can be switched directly; above that, or on three-phase motors, use the float as a signal into a magnetic contactor so the contacts only carry the coil current.
What cable length should I order?
Base it on tank depth plus the hysteresis you need between the fill and empty points, then add about 0.5-1 m of slack for the tie-off. Remember a longer cable lowers the trip point, so order a standard length (2, 3, 5, 10 or 15 m) rather than cutting to an odd size.
Float switch or electrode switch?
Use a float switch for non-conductive liquids, sludge and single on/off points, and where the switch must drive the pump directly. Use an electrode (conductivity) switch for clean conductive water and where several level points are needed from one controller.
Which IP rating do I need?
At least IP68 for a float that is continuously submerged in a sump or tank. Check the temperature range covers both the liquid and any steam or frost above it, and choose an oil- and chemical-resistant cable jacket for sewage pits.
