Maximum working pressure of flow switch: 1.0MPa; ambient temperature: 0~60°C; liquid temperature: 0~60°C; liquid temperature: -10~100°C (liquid not frozen); microswitch voltage: 220VAC - Note: When the flow rate exceeds the set value, the fluid actuates the vane and the microswitch, and the SPDT contact can energize one circuit and break other circuits - Application: The water flow switch is used to measure the dynamic state of fluids flowing through pipes, such as: water, ethylene dilution, glycol and other liquids that are not corrosive to copper - Flexible Regulation: Flow control value of the flow switch is adjustable, repeat action point is stable. The number of paddles and the length of the paddle can be adjusted to suit different pipe diameters and flow rates - Contents of the Package: 1 pcs water flow switch ## Technical Specifications | Specification | Value | |---------------|-------| | Actuator Type | Rotary | | Asin | B0D1VKV2LR | | Best Sellers Rank | #121,231 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #29 in Flow Switches | | Brand Name | Chazcool | | Circuit Type | 5-way | | Color | Blue | | Compatible Devices | Industrial control systems with appropriate input modules, such as PLCs and SCADA systems | | Connector Type | Screw | | Contact Material | Stainless Steel | | Contact Type | Spdt | | Control Method | Touch | | Control Type | flow_rate | | Current Rating | 15 A | | Customer Reviews | 4.5 4.5 out of 5 stars (6) 4.5 out of 5 stars | | Included Components | flow switch | | International Protection Rating | IP65 | | Item Dimensions | 3.35 x 2.56 x 4.92 inches | | Manufacturer | Chazcool | | Material Type | Plastic, Stainless Steel | | Model | 58466 | | Mounting Type | Surface Mount | | Number Of Items | 1 | | Number Of Positions | 1 | | Operating Voltage | 380 volts | | Operation Mode | ON-OFF | | Part Number | 58466 | | Specification Met | Hfs-25 1"/Dn25 Flow Switch | | Switch Type | Pressure Switch, Temperature Switch | | Terminal | Single Pole Double Throw | | Unit Count | 1 Count | | Upper Temperature Rating | 60 °C | ## Product Details - **Brand:** Chazcool - **Connector Type:** Screw - **Contact Type:** Spdt - **Current Rating:** 15 A - **Item dimensions L x W x H:** 3.35 x 2.56 x 4.92 inches - **Material:** Plastic, Stainless Steel - **Operating Voltage:** 380 volts - **Operation Mode:** ON-OFF - **Switch Type:** Pressure Switch, Temperature Switch - **Terminal:** Single Pole Double Throw ## Images ![HFS-25 1"/dn25 Water Flow Switch SPDT Contacts 6-380V - Image 1](https://m.media-amazon.com/images/I/511iwFo6OwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seems like quality, construction and adjustability. *by on Reviewed in the United States July 5, 2025* Great flow switch made of stainless steel. Close switches sensitive in spite of stainless steel Bellows. Wiring instructions suck because there are none. The two top screws are not for wiring their to hold the switch onto the device. The screws on the side or what you can use to wire the switch. It’s a single pole double throw switch so that you can either have it turn on with engages or turn off when it engages. I did not run much amperage through the switch, but it works for me. ### ⭐⭐⭐⭐⭐ Excelente *by on Reviewed in the United States May 31, 2025* Excelente producto ### ⭐⭐⭐ Not NPT *by on Reviewed in the United States February 9, 2026* Beware this is British treads not NPT ## Frequently Bought Together - Chazcool HFS-25 1"/dn25 Flow Switch, Water Flow Switch SPDT Contacts 6-380V, DN25 Stainless Steel Liquid Water Flow Paddle Control Switch - 6PCS Electromagnetic Power Relay, 8-Pin 10 AMP 110/120V AC Relay Coil with Socket Base, LED Indicator, DPDT 2NO 2NC - MY2NJ [Applicable for DIN Rail System] - GUETNEU Terminal Block, Rail Type Voltage Terminal, Rail Combined Terminal Block --- ## 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.lk/products/645859834-hfs-25-1-dn25-water-flow-switch-spdt-contacts-6](https://www.desertcart.lk/products/645859834-hfs-25-1-dn25-water-flow-switch-spdt-contacts-6) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-11*
