Description

The square float switch operates on a simple mechanical principle: as the liquid level rises or falls, the internal float tilts, actuating a hermetically sealed snap-action switch. This provides a dry contact output for automatic pump control or high/low-level alarm signaling. The double-chamber, remolded construction guarantees a hermetic seal (IP68), protecting the internal switch mechanism from liquid ingress and ensuring trouble-free operation in a wide range of non-flammable liquids.

Designed for industrial environments, the switch handles working pressures up to 0.1 MPa and operates within a temperature range of 0 to 75°C. Its robust plastic housing offers chemical resistance against water, sewage, oils, and many common industrial fluids, though it is not rated for explosive atmospheres. The device is a fundamental component for automated liquid level management in water treatment, HVAC, agricultural irrigation, and industrial process control systems.

Key Features

  • IP68 waterproof and dustproof construction for submerged or harsh wet locations.
  • High-current switching capacity: 10A @ 250V AC, enabling direct pump/motor control.
  • Durable plastic float and housing resistant to corrosion from water, oils, and mild chemicals.
  • Hermetically sealed switch chamber prevents internal contamination and ensures consistent contact operation.
  • Extended mechanical lifespan rated for 500,000 actuation cycles.
  • 2-meter PVC-jacketed cable allows for flexible mounting and remote installation.
  • Simple, reliable mechanical operation with no external power required for the sensing element.
  • Square float design provides stable buoyancy and consistent switching points.

Applications

  • Automatic pump control in water storage tanks, wells, and sump pits.
  • High/low-level alarm signaling in industrial process tanks and chemical vats.
  • Liquid level management for irrigation systems and agricultural water reservoirs.
  • Overflow prevention and dry-run protection for motors and pumps.
  • Level monitoring in sewage lift stations and wastewater treatment basins.

Frequently Asked Questions

What is the maximum electrical load this float switch can control?

This float switch is rated for a maximum of 10 Amps at 250 Volts AC, or 4 Amps at 380 Volts AC. It is designed to directly switch inductive loads such as single-phase pump motors, solenoid valves, or contactor coils within these limits. Always ensure your load's inrush and steady-state current do not exceed these ratings.

Can this switch be used in oil, fuel, or chemical tanks?

The plastic housing offers resistance to water, sewage, oils, and most mild acids and alkalis, making it suitable for many common industrial fluids. However, it is not explosion-proof. For use in potentially explosive atmospheres (e.g., fuel vapor), the switch must be used in conjunction with an appropriate intrinsically safe (Ex) isolator switch unit as per local safety regulations.

How do I wire this float switch for automatic pump control?

The switch provides a simple SPST (Single-Pole, Single-Throw) dry contact. Wire it in series with the power line to the pump control circuit or the coil of a contactor. Typically, the two wires (often blue and yellow) are connected to break the circuit when the desired liquid level is reached, stopping the pump. Consult the pump manufacturer's wiring diagram for integration specifics.

What is the meaning of the IP68 rating?

IP68 signifies complete protection against dust ingress (6) and protection against continuous submersion in water under specified conditions (8). This float switch can be permanently submerged in liquid, making it ideal for deep well, tank, and sump applications where the sensor is fully immersed during operation.

What is the difference between electrical life and mechanical life?

Mechanical life (500,000 cycles) refers to the number of times the float can physically actuate the internal mechanism without failure. Electrical life (100,000 cycles) is the number of reliable switching operations under the rated electrical load. The electrical life is typically lower due to contact wear from arcing when breaking the current.
