Feature Highlights: 1. Versatile Liquid Level Sensor – This float switch detects liquid levels in tanks and can trigger pumps, alarms, indicators, or other devices. Perfect for hydroponics, aquariums, water tanks, gardening, pet water bowls, ponds, HVAC drain pans, coffee machines, automotive uses, and many DIY projects. 2. Durable Stainless Steel Build – Made from corrosion-resistant stainless steel, it’s tough enough to handle various liquids and environments, from freshwater to saltwater setups. 3. Compact & Easy to Install – With a threaded diameter of 9.5mm and a total length of 119mm (4.6 inches), it fits neatly into tanks and containers. No complicated tools needed for setup. 4. Reliable Switching Performance – Features a max breakdown voltage of 220V, switch current of 0.5A, and can operate in temperatures from -30°C to +125°C for consistent, dependable operation. 5. Clear Activation Points – The float ball activates at a breaking height of 94mm (3.7 inches) and a 45-degree angle, giving you precise control over liquid levels. Product Details: This stainless steel horizontal float switch is designed to monitor liquid levels reliably in a wide range of applications. It works by floating up or down with the liquid, opening or closing an electrical circuit to control connected equipment like pumps or alarms. Thanks to its sturdy stainless steel construction, it resists rust and wear, making it suitable for long-term use in water tanks, aquariums, irrigation systems, marine environments, and more. The simple, tool-free installation lets you set it up quickly and start monitoring right away. Important Note: Because the switch carries a relatively low current (0.5A max), it must be connected to a relay or contactor when controlling higher-power loads. (Relay/contactor not included.)
