Flow Switch: Thomas Indoor 1" Pre-Wired Straight 110V 0.5 GPM

Pre-Wired 110v Flow Switch Makes It Easy to Automatically Control Chlorination / Peroxide System

Simply plug flow switch cord into any 110v wall outlet.  Then plug your chlorinator or peroxide chemical feed pump into the flow switch receptacle (outlet). When water flows, your pump will turn on.

What is the difference between the wired and non pre-wired flow switches?

The pre-wired flow switches come with a cord and a plug. You plug the flow switch into a wall socket. Then you plug a metering pump or other device into the flow switch, which has its own receptacle. When there is flow the receptacle energizes and turns on the pump etc. The non pre-wired ones, requires wiring.
