## Description

Main application:Magnetic Water Flow Switch adopts a Magnetic Reed Switch and a movable magnet which is fixed inside the water pipe. When water runs through the pipe part, the magnet will detect the water flow, and the magnet is shoved to one side by the flow. This then attracts the conductive strip which gets pulled down and makes contact, which completes the circuit and activates whatever electrical device you have attached to itSpecifications:Thread type: 1/2" BSP Male ThreadOperation voltage: 0-220V(AC or DC)Flow range: 1-30L/minWorking temperature: 1-120℃Mini start water pressure: 0.02MpaMax working pressure: 1.75 MPaMax loading power: 50WWorking current: 0-2AResponse time: 0.2SMaterial: BrassMale Thread External Diameter: 20.55mm(0.8 inches)Tube Length: 60mm(2.36 inch)Cable Length: 29cm(11.41 inch)Size: 60mm*30mm*30mm(L*W*H)Please Note:Don't forget to mark which way the old flow switch arrow is pointing so you can install exactly the same.When connecting the load, please add a relay.Package Include:Brass Flow Switch x 1

## Questions & Answers

**Q: Can it work as a 110 volt switch?**
A: They state it's safe for  0-220V(AC or DC), Working current: 0-2A.  Personally, I would not the wires are something like 28 gauge stranded.  you would need to be very careful about wiring.  I doubt it would ever pass an Electrical code review with 120v  open wiring in contact with a grounded water line.  I would suggest running a low voltage DC source to a power relay that could be enclosed in a junction box

**Q: Am I able to connect a 12 Volt water pump directly to this flow switch?**
A: No, it needs to add a relay board.
It cannot be directly connected to the circuit.

**Q: Can I get a replacement for the reed switch?**
A: They did replace mine with no issues.

**Q: Is this product lead-free?**
A: I suspect it is not lead-free, because it does not have any designation its lead content. Keep in mind that if this is used for regulation of intake to hot water system, the entirety of that plumbing system is full of lead. I got this as a replacement for a very-leaded part (colored silver) made by NTI

### ⭐⭐⭐⭐ Great Hot Water Recirculation Flow switch
*by M***E on August 2, 2020*

Used as a flow switch fro a tankless hot water heater recirculation loop. The switch closes (Activates / On) with less than 1GPM and stays closed below 1/2 GPM. I think it opens (Deactivates / Off)under 1/4 GPM The only issue is the leads are very thin and broke off during maintenance. I was able to take the switch module off the new assembly and install on the exiting on without turning the water off and changing out the whole body. I'm putting some Hot Glue on the wired connection on the switch body to avoid any other issues
