FSW301

FSW301 is a FSW300 series low cost flow switch comprises a paddle system with a permanent magnet attached, Above that magnet is a reed contact, located outside the flow of fluid. A second magnet with opposing poles, creates the force necessary to reset the switch back to the no flow position. The reed contact used as a sensing element consists of two ferro-magnetic contact blades located in a glass bulb filled with inert gas. This practically eliminates wear resulting from contact burning.
