The MAC3 Mac3 float switch (no cable) is a robust, double-chamber level switch engineered for reliable liquid level control in submersible and drainage pump systems. Designed and made in Italy, the Mac3 model is built for both clear and sewage waters and is widely used for pump protection, high-level alarm, and automatic on/off level control in tanks, cisterns and pumping stations.

Key performance features include an IP68-rated enclosure for permanent submersion, a shock-resistant double-body design that prevents infiltration, and high buoyancy thrust to handle gray or moderately loaded waters. The unit supports common microswitch ratings used in pump control circuits and offers dual-function operation for filling and emptying applications, making it versatile for retrofit and OEM installations.
