ABSTRACT:
The invention is directed to a flow control vertical switch for starting and stopping electric pump motors and being controlled by the level of a liquid using the flow of the liquid being moved to hold the switch in a switched position until the sump is depleted. The invention consists of a collar, a shaft rotatably mounted on the collar, a float arm having a magnet and a float mounted on the collar and a switch housing affixed on the collar above the magnet. A flow arm mounted on the shaft and located in the stream flow retains the magnet in switching position until the fluid stops running.
