ELEHPD manufactures cable float switches, ball and magnetic level switches for water tanks, wells, sumps and pump control — alongside circuit breakers, contactors, relays and distribution boxes for distributors, OEMs and panel builders worldwide.
Explore Float Switches Get a QuoteELEHPD manufactures cable float switches, ball float switches and magnetic level switches for clean water, sewage, sump and submersible pump duty. Typical catalogue ratings are 250 V (380 V max), 10 A, IP68, polypropylene body with PVC or rubber cable from 2 m to 15 m — exact values are confirmed per model before production.
Attached to the tank wall or suspended on its own cable; switches a contactor or starts a pump directly. The standard choice for water tanks and wells.
VIEW DETAILS →Solid floating ball with the microswitch sealed inside — compact, simple and widely used for small tanks, boilers and RO units.
VIEW DETAILS →A reed switch driven by a magnet inside the float — no direct contact with the liquid, good for level alarms and PLC inputs.
VIEW DETAILS →Sensor heads for flow detection and multi-point level control where a simple pump start/stop is not enough.
VIEW DETAILS →Yes for small single-phase pumps whose running current sits comfortably below the contact rating — typically up to 10 A at 250 V with our standard contacts. For three-phase motors or anything larger, run the float as a signal into an AC contactor so only coil current passes through the float contacts.
A cable float switch works in almost any liquid, including non-conductive water and sewage, and is usually enough for one-start-one-stop control. An electrode (conductivity) relay needs clean conductive water but gives several level set points from one controller — a better fit for multi-point alarms and PLC-driven systems.
Tank depth plus the hysteresis you want between the fill and empty points, with roughly 0.5–1 m extra for the tie-off. A longer cable also lowers the trip point, so pick a standard length (2, 3, 5, 10 or 15 m) rather than trimming to an odd size.
IP68 for anything permanently submerged. Our standard float series is built to IP68 with a polypropylene body and sealed PVC or rubber cable entry; confirm the exact rating for your model and medium before ordering.
Float switches are our speciality, and shipments can be combined with the rest of our low-voltage production — MCB, MCCB, RCBO, ELCB / RCCB, AC contactors, thermal relays, fuses, busbars, surge arresters, distribution boxes and power supplies — so consolidation does not cost you a second supplier.
