1. a current inductive switch, is characterized in that:

  • comprise that two ends are respectively equipped with the housing of water inlet (12) and delivery port (13), elastic reset film part (5), magnetic patch (4) and magnetic induction circuit plate (8);

    Described housing inner side is provided with installation cavity (10), and the water inlet (12) on housing is communicated with delivery port (13) by installation cavity (10);

    Described elastic reset film part (5) and magnetic patch (4) are in housing (1) inner side;

    The bottom of described elastic reset film part (5) is that elasticity gets lodged in the pushing post portion (53) in installation cavity (10), top be one around and be fixedly connected on the annular deformation film (52) of pushing post portion (53) top periphery wall;

    Described annular deformation film (52) top is pressed on housing (1) one side inwall;

    The annular deformation film (52) that described magnetic induction circuit plate (8) is in outside housing (1) and its position is interior with housing (1) is corresponding;

    Described magnetic patch (4) is inlaid in pushing post portion (53) top ends;

    Described magnetic patch (4) is to leaving the induction spacing changing with annular deformation film (52) deformed state between magnetic induction circuit plate (8).
