Avoid dangerous overflows in your liquid container using this vertical float switch from Sensata Cynergy3. The float on the surface of the liquid has an internal magnet that flicks the switch to the open or closed position as the level changes. Thanks to its broad operating temperature range of -20°C to +75°C, it's suitable for use in demanding environments. For increased versatility, you can reverse the switch action to NO (normally open) or NC (normally closed) to suit your application by removing the float, rotating it through 180° and then refitting it. A float switch like this one is often used in water treatment plants or breweries.

• Nitrile gasket ring is resistant to chemicals and wear for a reliable, leak-proof seal
• Nylon body material is abrasion-resistant for a long service life

The switch has a 1/8-inch BSP thread, so you can screw the switch securely in place in your tank.
