Side-mounted water level switch that can be installed as normally closed or normally open to suit your control logic. Key benefits - Simple, reliable liquid level control that automatically turns pumps, indicators, alarms, or other equipment on or off. - Small, floating design with corrosion resistant construction for durable long-term use in liquid environments. - Flexible operation with a choice of normally closed or normally open wiring to match your system requirements. What it does - Detects the liquid level in a tank and triggers connected devices to maintain desired levels or protect equipment from dry running. Compatibility and use cases - Suitable for: hydroponics systems, sea water tanks, water tanks, gardening projects, aquariums, and fish tanks. - Ideal for low-power control circuits and devices that operate within its electrical limits. Electrical and physical specifications - Maximum switching voltage: 100 V DC - Maximum switching current: 0.5 A - Floating level switch with compact size and corrosion resistant, built for long-term use Practical applications - Hydroponics reservoir: monitor growth solution level and automatically start/stop the water pump to maintain steady nutrient concentration. - Aquarium or fish tank: automate top-off or trigger an alert when water level falls below a safe threshold. - Water storage or garden system: serve as an inline level monitor to activate a pump or alarm, preventing overflow or dry operation.
