The blade flow switch uses the movement of liquid to drive the blade to shift, testing whether the liquid is in a flowing state. When the liquid is not flowing, the blade remains in its natural position. When the liquid flows, its impact forces the blade to shift, which, through a transmission shaft, activates a microswitch to output a contact signal.
