Since it does not use a spring, there is little aging change, and there is no concern about rust or corrosion. The reed switch, fixed to the outside of the main body, is turned ON-OFF by the magnet inside the operating flapper of the water flow section. When flow occurs, the flapper swings towards the reed switch, turning the switch ON, and when the flow decreases, the flapper is pulled back by the attraction between the magnet of the flapper and the external magnet of the main body. (Reverse mode can also be produced.) 【Features】 ■ Little aging change, with no concern about rust or corrosion ■ ON-OFF operation of the reed switch is controlled by the magnet inside the operating flapper of the water flow section *For details, please request materials or view the PDF data from the download.
