Description

The P35 Float Level Switch operates on a simple mechanical principle: the buoyant polypropylene float rises or falls with the liquid level, physically actuating an internal sealed switch. This provides a direct, unpowered electrical contact change (NC operation) for reliable level monitoring without complex electronics or signal conditioning.

Designed for general-purpose liquid level control, this switch is suitable for water, oils, and non-aggressive fluids within its operating temperature range of -10°C to 60°C. Its compact form factor and straightforward two-wire connection (via the attached cable) facilitate easy integration into pump control circuits, tank overflow alarms, and industrial automation panels.

Key Features

  • Mechanical, Normally Closed (NC) switch operation for simple on/off control.
  • Polypropylene (PP) float material offers good chemical resistance and durability.
  • Compact and lightweight design (8g) minimizes system impact and simplifies mounting.
  • Rated for a wide voltage range up to 220V AC/DC for versatile application compatibility.
  • Pre-wired with a 35cm cable for immediate installation and connection.
  • Operates across a -10°C to 60°C temperature range for use in various environments.
  • High-value build provides reliable level sensing for basic control and alarm functions.

Applications

  • Residential and commercial water tank level control for pump activation/deactivation.
  • Overflow or low-level alarm systems in industrial fluid storage tanks and reservoirs.
  • Liquid level monitoring in agricultural irrigation systems and hydroponic setups.
  • Basic fluid presence detection in machinery sumps, bilges, and equipment cooling systems.

Frequently Asked Questions

What does NC (Normally Closed) mean for this float switch?

NC means the switch contacts are closed (conducting) when the float is in its resting, lowered position (low liquid level). When the liquid rises and lifts the float, the internal mechanism opens the contacts, breaking the circuit. This configuration is often used for pump-down control or low-level alarm circuits.

What is the maximum voltage and current I can switch with this float switch?

The switch is rated for a maximum switching voltage of 220 Volts AC or DC. The maximum switching current is 0.5 Amps. Do not exceed these ratings, as they define the safe operational limits for reliably opening and closing the electrical load connected to the switch contacts.

What liquids is this Polypropylene (PP) float suitable for?

The Polypropylene (PP) float body offers good resistance to water, many oils, dilute acids, and alkalis, making it suitable for general-purpose applications. It is not recommended for use with strong solvents, concentrated acids, or hydrocarbons like gasoline. Always verify chemical compatibility for your specific fluid.

How do I wire and install this float switch?

Installation is straightforward: mount the switch vertically in the tank using its threaded boss or a suitable bracket. Connect the two wires from the 35cm cable in series with your load (e.g., pump, relay, indicator lamp) and power source. Ensure the wiring respects the voltage and current ratings, and that the float moves freely without obstruction.
