A flow-rate switch particularly suited for use in detecting variations in flow rates for fluids flowing through conduits of pressurized systems characterized by the utilization of a magnetically responsive circuit switching device seated within a tubular housing and a ring magnet concentrically disposed about the housing adapted to be repositioned in opposite directions along the housing for effecting circuit switching operations in response to changes in flow rates, a feature of the switch being the employment of a flow-responsive and variably positioned pintle disposed about said housing, within the path of the fluids, supporting the magnet for displacement relative to said switching device for repositioning the ring magnet relative to said switching device to effect switching operations as variation in flow rates occur.
