The Series V7 Flotect® Flow Switch is an inexpensive range switch for use with compatible liquids to start or stop electronic operated equipment when flow or no-flow conditions occur. Design is standard weatherproof, meeting NEMA 4X.

• Superior performance with magnetically-actuated switching design
• Increased product life due to free-swinging vane, which attracts a magnet within the solid metal switch body to actuate a snap switch by means of a simple lever arm with no bellows, springs, or seals to fail
• Meets application requirements with durable leak proof body machined from bar stock
• Long operating life with robust vane design which is rigid and field trimmable for set point adjustment
