Frequently Asked Questions
Q: What types of water pumps is this flow switch compatible with?
A: This 1-inch G1 thread magnetic flow switch is compatible with self-priming pumps, booster pumps, and jet pumps rated up to 200W at 220V AC. Always verify your pump's voltage and power rating before installation.
Q: How does the magnetic automatic flow switch work?
A: The switch uses a magnetic sensor combined with a sensitive spring mechanism to detect water flow through the pipe. When water flows, it triggers the switch to activate the pump; when flow stops, the switch automatically cuts power — providing fully automatic, hands-free pump control.
Q: Is this flow switch suitable for high-voltage systems?
A: Yes. This flow switch is rated for 220V AC (above 50V AC threshold), making it suitable for standard mains-powered pump installations. Ensure all electrical connections are made by a qualified professional and comply with local electrical codes.
Q: Does the package include batteries or additional fittings?
A: No batteries are required or included — the switch operates on your mains-powered pump circuit. The package includes 1 × flow switch only, with no additional fittings or retail packaging.
