Level Control

Cable Float Switch Water Flow Level Control

Walax cable-suspended water float switch with copper-core cable and PP/ABS float body. Mercury-free micro-switch rated 10A/250VAC drives pumps directly without external contactor, ideal for water tank level control, sump pump duty and sewage applications with suspended solids.

Mercury-Free SPDT

10A/250VAC micro-switch drives up to 1.1kW pump directly without an external contactor, lowering install cost.

Copper-Core Cable

Pure copper conductor with PVC or H07RN-F rubber jacket for long flex endurance and low voltage drop.

IP68 Submersible

Hermetically sealed double-chamber float body survives continuous submersion in sewage and effluent tanks.

Applications

Where These Float Switches Install

Water tank level control, sump and sewage pump duty, drainage pits and rainwater harvesting tanks. The streamlined float profile passes suspended solids freely, making it suitable for waste-water and lightly contaminated liquids.

FAQ

Frequently Asked Questions

Can it drive a pump directly?

Yes – the 10A/250VAC SPDT micro-switch can start pumps up to 1.1kW directly, without needing an external contactor.

Is it mercury-free?

Yes. The micro-switch uses a mechanical ball-and-mercury-free design that meets RoHS and modern environmental requirements.

What cable length can I order?

Standard lengths are 2, 3, 5, 10 and 20 metres; custom lengths up to 30m are available on request.

Can it be used in sewage?

Yes – the streamlined PP float body and IP68 sealing handle sewage, sump and lightly contaminated liquids with suspended solids.

How is the switching level set?

By positioning the counter weight on the cable. The 28° ± 2° switching differential gives clear hysteresis between pump-on and pump-off levels.

What is the protection rating?

IP68 (continuous submersion to 10m water depth) with a working pressure rating of 1.0 bar.

Do you provide test reports?

Yes – IEC 60730 type-test reports and CE documentation ship with every order. Country-specific certifications on request.
