Product Description The Horizontal Float Level Switch is a highly reliable, side-mounted liquid level sensor designed for sensing the level of liquid within a tank. Unlike vertical sensors, this horizontal model is ideal for shallow tanks or containers where top-mounting is not feasible. It uses a magnetic reed switch mechanism: as the water level rises or falls, the float moves, triggering the internal switch to either open or close a circuit. Made from corrosion-resistant PP plastic, it is widely used in water dispensers, humidifiers, and DIY automated tank-filling systems.

Key Features

  • Flexible Mounting: Side-mounted design allows for installation in narrow spaces or tanks where access to the top or bottom is restricted.

  • Corrosion Resistant: Constructed from high-quality Polypropylene (PP) plastic, making it suitable for water and mild chemical applications.

  • Simple Interface: Operates as a simple passive switch (ON/OFF), making it easy to interface with any microcontroller or relay module.

  • Adjustable Logic: The switching logic (Normally Open or Normally Closed) can often be reversed by simply flipping the float 180 degrees.

  • High Sensitivity: Features a lightweight float that reacts to minimal changes in liquid level for precise overflow or run-dry protection.

Technical Details

  • Operating Principle: Utilizes a permanent magnet inside the float to actuate a hermetically sealed reed switch in the stem.

  • Switching Voltage: Optimized for low-voltage DC signals (100V Max), perfect for 5V-24V control logic.

  • Load Handling: Can directly trigger low-power indicators or signal pins; high-power loads like pumps must be controlled via a relay.

  • Mechanical Life: Rated for over 1 million operations due to the friction-free magnetic switching mechanism.

  • Environmental Sealing: The internal reed switch is completely isolated from the liquid, preventing oxidation and short circuits.

  • Installation: Requires a 16mm hole in the side of the tank; includes a silicone gasket and plastic nut for a leak-proof seal.

  • Wire Quality: Equipped with standard 1007/24AWG leads, typically 30-40cm in length for easy routing.

  • Pressure Tolerance: Designed for non-pressurized or low-pressure (0.2 MPa) atmospheric tanks.

  • Buoyancy Design: The float density is optimized to ensure it floats reliably in water and similar density fluids.

  • Response Time: Near-instantaneous switching (milliseconds) for real-time level monitoring.

  • Temperature Stability: Maintains consistent switching points across its full rated temperature range.

  • Low Profile: Small internal protrusion ensures it doesn't interfere with other internal tank components.

  • Maintenance-Free: No moving mechanical linkages or springs to wear out or clog with mineral deposits.

  • Safety: Non-toxic plastic construction is safe for use in drinking water systems or aquariums.

  • Standardization: M16 threading is a standard size, compatible with most industrial and hobbyist tank fittings.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not connect a high-power water pump directly to the float switch and a 9V battery. The switch is only rated for 0.5A; a pump will burn out the internal reed switch instantly. Use the switch to trigger a Relay Module instead.

  • 18650 Cell: For remote tank monitoring, a single 18650 cell (3.7V) is perfect for powering an ESP32 or Arduino that monitors this switch. Use a 10k Ohm Pull-up Resistor to ensure a stable digital signal.

  • IC & Capacitor Tip: If the water surface is turbulent (wavy), the switch might "chatter" (rapidly turn on/off). Solve this in your code by adding a Debounce Delay (e.g., 500ms) or by adding a 10uF Capacitor across the signal pins to smooth out the transitions.

  • Related Products: We recommend pairing this with our 5V Relay Modules, DC Water Pumps, and 16x2 I2C LCD Displays to show the current tank status.
