PROBLEM TO BE SOLVED: To provide a water stream switch surely operating in accordance with presence or not of a water stream in a fluid flow channel. SOLUTION: The water stream switch 1 is provided with a casing 10 forming a fluid flow channel inside, a magnetic body 21 fitted in the flow channel of the casing 10 and rocked when water stream is generated in the casing 10, a support body 22 supporting the magnetic body 21, and a reed switch 40 becoming a closed state by approaching of the magnetic body 21. Since the water stream switch 1 has formed the support body 22 of an elastic material, the support body 22 elastically bends by receiving running water pressure irrespective of presence of foreign substances getting entangled to the support body 22. With this, the magnetic body 21 is structured to surely approach the reed switch 40 in case the water stream is generated in the casing 10, whereby the reed switch 40 can be in a closed state.
