  • FSW-20 series paddle-type switches easily install into pipes ranging in size from 1¼" on up using an ordinary pipe tee or threaded weld coupling. The paddle pivots to move out of the liquid’s path with increasing flow, thereby activating the switch. The paddle is easily cut for field installation for desired flow setting. Models FSW-21 and FSW-22 feature high pressure (2000 psig max.) and high temperature (to 150°C (300°F)) ratings for rugged installations.
