Doing the job
I was surprised to actually find this on Amazon. Amazon 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 Amazon. Also, smart Amazon 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.

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.

Worked, Sort Of
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.

Not a NPT thread some British thread type
I’m sure it would work great if it were the right thread type. Based on measurements it is some type of British thread
