Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a float switch allowing prevention of operation failure caused by the interposition of a foreign matter above the float. SOLUTION: In this float switch, a float 5A is vertically movably fitted on a vertically extending guide shaft 4. The float 5A is provided with a magnet 6 in the inner circumference. When the float 5A ascends, a reed switch 7 inside the guide shaft 4 responds to magnetic flux of the magnet 6 and is turned on. Even if the foreign matter exists between the float 5A and an upper face part of a hot-water tank 2, the ascending float 5A ascends with pushing the foreign matter aside to ascend without influence of the foreign matter.
