摘要： The present invention provides a flowswitch for installing in piping, featuring a flowswitch base having an inner cavity; a pivot rod being arranged for rotating in the flowswitch base, the pivot rod having a pair of O-ring grooves; a paddle arm being coupled to the pivot rod inside the cavity, for moving in response to fluid flowing in the piping and rotating the pivot arm; lubricating O-rings being installed onto the pivot rod with each O-ring arranged in a respective O-ring groove for providing a respective seal between fluid being sensed and the outside environment and acting as a bearing on which the pivot rod rotates when the paddle arm moves, the grooves acting to holding the O-rings in place on the pivot arm in response to pressurized fluid flowing in the piping; and an actuating arm being coupled between the pivot arm and the pivot rod for actuating a switch when the pivot arm rotates.
