This float switch from Sensata Cynergy3 is used to measure the level of liquid in a tank, reservoir or sump. It's typically used to control other devices such as alarms and pumps when the liquid rises or falls to a specific point. The vertical-mount switch is fitted internally, so it's a good choice for use when there's top or bottom access to the inside of the tank. As the switch is made from 316-grade stainless steel, it's strong and resistant to damage from rust and corrosion. The compact unit is a popular choice for home appliances, like dishwashers and washing machines.

• Universal mounting thread of 1/8 NPT (national pipe thread) makes it simple to mount in modular systems
• Wide operating temperature range of -20°C to +120°C for use in a variety of demanding industrial environments
• User-configurable NO (normally open) or NC (normally closed) contacts for versatility

To reverse the switch action, simply remove the float, invert it and then refit it to the stem.
