1. current inductive switch, it is characterised in that:

  • include housing, elastic reset membrane (5), magnetic piece (4) and magnetic induction wiring board (8);

    Described shell one end has water inlet (12), the other end of described housing has outlet (13), case inside is provided with installation cavity (10), and the water inlet (12) on housing connects outlet (13) by installation cavity (10);

    Described elastic reset membrane (5) and magnetic piece (4) are in housing (1) inner side, the bottom of described elastic reset membrane (5) is to push post portion (53), top is an annular deformation film (52) surrounding and being fixedly connected on pushing post portion (53) top peripheral wall, and described pushing post portion (53) elasticity gets lodged in installation cavity (10);

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

    Described magnetic induction wiring board (8) is in housing (1) outside and its position is corresponding with the annular deformation film (52) in housing (1);

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

    Described magnetic piece (4) leaves the sensing spacing changed with annular deformation film (52) deformed state between magnetic induction wiring board (8);

    Hydraulic pressure pushes away when making annular deformation film (52) deformation, installation cavity (10) connection water inlet (12) and outlet (13), and drive magnetic piece (4) mobile to magnetic induction wiring board (8), make sensing spacing reduce and sense magnetic signal to magnetic induction wiring board (8);

    Installation cavity (10) includes the cylindrical interior volume being available for pushing post portion (53) longitudinally-moving surrounded by cylindrical wall and the outlet pass (101) being arranged on cylindrical wall;

    The bottom of cylindrical interior volume connects with water inlet (12);

    Outlet (13) the inner extends to around cylindrical wall periphery place, and connects into the mouth of a river (12) by the outlet pass (101) on installation cavity (10)。
