Abstract
A flow switch adapted to be attached to a pipe is designed to trip a switch at a preset flow rate. The switch employs a bending metal blade which deflects in the flow stream to move a magnet attached to the downstream side of the blade relative to a reed switch or Hall-effect switch. The switching device is preferably mounted in a slot on a printed circuit board to enable selection of a range of available trip points.
