And connecting the wire carefully. - This flow switch is made of high quality stainless steel, corrosion resistant and long service life. - Flow switches are typically used in locations that require interlocking or "cutting" protection.When the flow exceeds the set value, the fluid drives the blade and microswitch, and the SPDT contact can connect the circuit and disconnect other circuits. - Special grounding screws should be used for wiring, and the installation screws cannot be removed. The blade of the flow switch cannot contact the inner wall of the pipe and other regulating valves of the pipe, otherwise the switch cannot be reset normally. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q5ZD8WC | | Actuator Type | Hinge Lever | | Best Sellers Rank | #209,111 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #52 in Flow Switches | | Brand Name | YWBL-WH | | Circuit Type | multi-way | | Connectivity Protocol | X-10 | | Connector Type | Screw | | Contact Material | Stainless Steel | | Contact Type | Normally Open | | Control Method | Touch | | Current Rating | 15 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (19) | | International Protection Rating | IP65 | | Item Dimensions | 3.35 x 2.56 x 4.92 inches | | Item Weight | 0.52 Kilograms | | Manufacturer | YWBL-WH | | Material Type | Plastic, Stainless Steel | | Model | YWBL-WHy7wxqc2410 | | Mounting Type | Surface Mount | | Number of Positions | 1 | | Operating Voltage | 380 Volts | | Operation Mode | ON-OFF | | Specification Met | Ip65 | | Switch Type | Pressure Switch, Temperature Switch | | Terminal | Spdt | | UPC | 747333419603 | | Unit Count | 1.0 Count | | Wattage | 3300 watts | ## Product Details - **Operation mode:** ON-OFF - **Current rating:** 15 Amps - **Operating voltage:** 380 Volts - **Contact type:** Normally Open - **Connector type:** Clamp ## Images ![YWBL-WH HFS-25 1" Flow Switch dn25 Liquid Water Flow Paddle Control SPDT Contacts 6-380V - Image 1](https://m.media-amazon.com/images/I/51b5d7gF69L.jpg) ## Questions & Answers **Q: Is this good for potable water system?** A: Parts are made of stainless steel so I don't see any reason why it could not be used for potable water. **Q: what thread size and is it NPT or G or R?** A: Npt **Q: Does it work if i want to make a circuit with 5V?** A: Yes **Q: What are the on/off flowrate adjustment possibilities of this switch and the pressure drop through the unit at (say) 8 gpm?** A: Adjustment is almost infinite. Different sized paddles and adjustable microswitch. Very little if any flow loss. Paddles are thin and very flexible. ## Frequently Bought Together - HFS-25 1"/DN25 SPDT Contacts Water Switch, Liquid Water Paddle Control Switch 6-380V - GEYA Delay Off Single Function Time Relay 2 Outputs 16A Electronic Power Off Timer Delay Relay(GRT8-B2,AC/DC12V-240V) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/584475127-ywbl-wh-hfs-25-1-flow-switch-dn25-liquid-water](https://www.desertcart.tn/products/584475127-ywbl-wh-hfs-25-1-flow-switch-dn25-liquid-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
