## Description

HFS-25 1"/DN25 SPDT Contacts Water Switch, Liquid Water Paddle Control Switch 6-380V: desertcart.com: Industrial & Scientific

Review: Doing the job - I was surprised to actually find this on desertcart. desertcart is really great and changing life to a better way. I have a project where I have a water pick-up pump that is feeding a high pressure sending pump. The high pressure pump needs to work only when water is flowing to an electric side valve. In case the pick up pumps fails, I need the system to shutdown. I was thinking about the possible solutions and technologies and I found this one on desertcart. Also, smart desertcart suggested getting a timer with this. I didn't know I'd need it but it was a good advice. It has been a while since I installed everything. System is working as expected. No issues and very good set of blades to set the flow intensity and the pipe size.
Review: Me agrado el surtido de paletas; la capacidad de manejo de corriente de los contactos. Bajo perfil y para tubería de una pulgada, permitió instalación sin adaptadores el lugar apretado.

## Features

- This product is used to measure the fluid dynamics of fluids passing through pipes, such as water, ethylene diluents, glycols and other liquids that do not corrode copper.
- This water switch is suitable for water treatment systems, central air conditioning, water cooling units, fire systems and other fields.
- This switch is made of high quality stainless steel, and long service life.
- switches are typically used in locations that require interlocking or "cut" .
- When the exceeds the set value, the fluid drives the blade and the microswitch, and the SPDT can connect the circuit and disconnect other circuits.

### ⭐⭐⭐⭐ Worked, Sort Of
*by H***. on July 8, 2023*

Sturdy, and made of stainless steel. The placement of this switch must be well thought out, as it didn't work where we wanted to use it in our plumbing project.
