Float Switch Water Level 10A 250V Submersible IP68 for Water Pump Tank

This water level float switch is a reliable, maintenance-free liquid level control solution for water pumps, sump pumps, sewage systems, tanks and wells. The hermetically sealed float body is rated IP68 — dust-tight and fully submersible — with a T85 temperature class, ensuring stable operation in harsh, wet environments. Simply hang it in the tank: as the liquid rises or falls, the float tilts and directly switches the pump on or off, with no electronics, probes or external controller required.

Rated 10(8)A at 250V~ and 10(4)A at 380V~, it can directly drive most single-phase and three-phase pump motors. The included adjustable counterweight lets you set the switching level precisely, while the heavy-duty 3-core cable (blue, brown, yellow-green earth) provides safe, polarized wiring.

Feature&Selling Points

IP68 fully sealed waterproofing: dust-tight and long-term submersible; suits humid and sewage environments

Mechanical direct drive: float tilt directly switches the circuit — no power, probes or controller needed; low failure rate, long service life

High load capacity: 10(8)A 250V~ / 10(4)A 380V~, directly drives single-phase and three-phase pumps without an intermediate relay

Adjustable counterweight: precisely sets the switching level by adjusting the counterweight position to fit different tank depths

T85 temperature class: suitable for hot water and high-temperature liquid environments

Safe 3-core wiring: blue / brown / yellow-green earth, compliant with electrical safety requirements

Maintenance-free: no active electronic parts, stable long-term operation, simple hang-and-use installation
