PROBLEM TO BE SOLVED: To provide a water flow switch capable of simplifying a structure, and improving workability in assembling. SOLUTION: This water flow switch 10 installed in an intermediate part between a bathtub and a heat exchanger in a reheating circuit for detecting the presence of a water flow in the circuit is composed by housing a detection unit 14 comprising a detection piece 15 and a shaft body 18 in a detection chamber 12 formed by hollowing out the inside of a body 11. The detection piece 15 is rotatably supported to the shaft body 18. The detection chamber 12 is so structured that an opening hole 12A for inserting the detection unit 14 in assembling is formed; and the opening hole 12A is closed with a lid body 13. Since the flow switch 10 is so structured as to catch the detection unit 14 by a shaft body receiving part 12T and the lid body 13, its structure can be simplified, and workability in assembling can be improved.
