Float Switch Overview A simple, reliable plastic float switch for liquid level detection and control. Designed for inline installation with a 11/4 BSP threaded port, this compact unit offers straightforward operation and easy fitment for tanks and pump systems. Key benefits Automatic level control: Detects rising and falling liquid levels to trigger pumps, valves, or alarms without continuous monitoring. Easy to install: Standard 11/4 BSP thread fits common tank and sump ports for quick replacement or installations. Lightweight and corrosionresistant: Plastic construction and a beige finish make the switch suitable for noncorrosive fluids and environments where metal parts are not desirable. Compact footprint: Ball diameter of 84 mm provides a clear buoyant action while keeping the overall size manageable for tight spaces. Simple maintenance: Singlepiece design and common thread size reduce downtime for servicing or replacement. Features and specifications Product name: Float Switch Material: Plastic Main color: Beige Ball diameter: 84 mm (3.3 in) Thread diameter: 41 mm (11/4 BSP) Net weight: 160 g Package content: 1 x Float Switch Function and compatibility Function: Buoyant float actuates an internal switching mechanism as liquid level changes, enabling control of external devices such as pumps, valves, or warning systems. Compatibility: Designed to fit standard 11/4 BSP threaded ports commonly found on domestic and light commercial tanks, sumps, and cisterns. Suitable for use with water and other noncorrosive liquids compatible with plastic. Performance and installation notes Install vertically into a threaded port using appropriate sealing thread tape or gasket as required by the installation. Ensure the float has sufficient travel and clearance inside the tank for reliable switching. Avoid use with strong solvents or abrasive fluids that can degrade plastic components. Use scenarios 1) Sump pump control: Automatically switch a sump pump on as the float rises in a basement sump and off as the water level falls, reducing the need for manual intervention. 2) Water storage tank level management: Maintain a constant supply by controlling a fill valve or pump in a domestic water tank with a standard 11/4 BSP port. 3) Small aquaculture or irrigation systems: Monitor and control water levels in smallscale fish tanks or irrigation reservoirs where plastic construction is acceptable. What makes it stand out Straightforward compatibility with common BSP threaded fittings provides a hassle replacement or installation option. Lightweight and compact design simplifies handling and reduces installation effort. Clear, fixed dimensions and singlepiece package content make planning and ordering easier. Included in the box One float switch, ready for installation. Note Confirm fluid compatibility with plastic materials before use and verify that the 11/4 BSP thread matches the installation point.
