Perfect for instant electric water heaters, garden irrigation, or small-scale plumbing, this plastic flow switch ensures precise water control, leak prevention, and energy efficiency in a compact, user-friendly package.


Why Our Plastic Flow Switch Stands Out

1. ​L-Shaped Space-Saving Design
Engineered with a unique L-shaped inlet/outlet structure, this switch fits seamlessly into tight spaces under sinks, behind appliances, or in portable setups, reducing clutter while maintaining optimal flow efficiency.

2. ​Ultra-Durable Construction
Crafted from nylon reinforced with fiberglass, it resists corrosion, high-pressure surges, and extreme temperatures (-30°C to 120°C), making it ideal for hot water systems, outdoor use, or humid environments.

3. ​Waterproof & Explosion-Proof Safety
Built to meet rigorous safety standards, its sealed housing protects against water ingress and electrical hazards, ensuring reliable performance in bathrooms, kitchens, and workshops.

4. ​Dual Functionality
Use it as a flow switch to detect water presence/absence (e.g., triggering instant water heaters) or as a meter to track consumption—ideal for optimizing energy bills or monitoring irrigation systems.

5. ​Plug-and-Play Simplicity
With a compact 58x38x38mm size and 1/2 G universal threads, installation takes minutes. No technical expertise is required—just connect to pipes, hoses, or DIY projects and start monitoring.
