A flow switch that operates according to the flow rate of a fluid, comprising a rotor that rotates at a speed approximately proportional to the flow rate of the fluid, and a sensor that generates a pulse signal by the rotation of the rotor. , a comparator that compares the pulse width or pulse period of the pulse signal output from the sensor with a predetermined set time. 2. The comparator is configured to compare the pulse width of the pulse signal output by the sensor with the pulse width of a constant width pulse signal synchronized with the rising edge of the pulse signal. Claim 1 of the Utility Model Registration Claim: Flow switch as described. 3. The flow switch according to claim 2, wherein the comparator is a D flip-flop which uses the falling edge of the pulse signal as a clock input and uses the comparison pulse signal as a D input. 4. The flow switch according to any one of claims 1 to 3, which includes an integrator that integrates the output of the comparator. ~
