<h2>What is a Float Switch?</h2><p>A float switch is a level sensor used to detect the level of liquid usually in a tank, container or well. The flotation part of the device sits on top of the liquid and will switch on the rise and fall of the liquid. Float switches are used for automatic level control of groundwater, wastewater, and sewage pumps, for raw water and liquid transfer pumps at waterworks, and for high water alarm.</p><h3>How does a Float Switch work?</h3><p>Float switches have a reed switch and a pivoted magnet and can be used for normally open (N/O) or normally closed (N/C) operation. The switch action can be reversed rotating the switch through 180&deg;.</p><p>The switch sits on top of a water level and the changing fluid level will cause the reed change to work (for instance close or open) at a specific level. The internal mechanical switch opens or closes the electrical circuit with gravity which enables it to turn equipment on and off such as a water pump.</p><h3>What materials are float switches made of?</h3><ul><li>Nylon &ndash; used for oils, diesel, organic chemicals.</li><li>Polypropylene (PP) &ndash; acids and alkali, detergents, oils, water, organic chemicals.</li><li>Polyphenylene sulphide (PPS) &ndash; used for more aggressive chemicals, and higher temperatures, up to 120&ordm;C.</li><li>Stainless steel &ndash; medical and food industries, hydraulic fluids, chemicals.</li></ul><p><strong>Features and Benefits</strong></p><ul><li>Highly Flexible</li><li>High Mechanical Load Rating</li><li>Insensitive to Turbulence</li><li>Shock and Rupture Proof</li><li>WRAS approvals</li></ul><p><strong>Applications of Float Switches</strong></p><p>Float Switches can be used in several situations, some of which include:</p><ul><li>Sump Pits</li><li>Fuel Tanks</li><li>Coolant Tanks</li><li>Oil/Water Separators</li><li>Wastewater and Sewage Treatment</li></ul><p>Browse the broad range of Float Switches RS Group has to offer and order today for next day delivery</p>

<p>Cynergy3 offer a wide range of float switches designed, tested and manufactured to the highest standards, ensuring a quality product that's made to last!</p><h2>Why choose a Cynergy3 float switch?</h2><p>A float switch is a type of level sensor designed to detect the level of liquid in a tank. Cynergy3 float switch units rely on reed switch technology to control their switching action. A magnet is mounted within the float and a reed switch is mounted within the body of the unit. When a change in liquid level moves the float and brings this magnet into close proximity with the reed switch, the switch will change state. If the reed switch is normally open, the magnet will close the switch. If the reed switch is normally closed, the magnet will open the switch. This magnetic N/O or N/C option allows the user flexibility in their electrical circuit design. Float switches may have multiple floats and/or multiple reed switches allowing for multi-level signalling or multiple switching action within a single unit.</p><p>Cynergy3 float switches have many bespoke configurations making them suitable for a variety of applications such as: be used as an alarm, as an indicator, to control a pump, or to provide a signal to another device.</p><h3>Things to consider when selecting a float switch:</h3><ul><li>The fluid level state and the likelihood of deposit build-up</li><li>The fluid type - Cynergy3 float switches and associated gaskets and seals are available in many materials to give a broad range of suitability</li><li>Electrical load to be switched - Voltage, Current, Power, resistive, capacitive or inductive</li><li>Working temperature and pressure</li><li>Mounting type - Horizontal or vertical, external or internal, depending on the space available within the tank or sump</li><li>Cable and connection - Flying lead or connector, cable length and type</li><li>Approvals required: WRAS, ATEX, UL, NSF, etc.</li></ul>
