On shell fragment and the 5th wire 1015 on magnet of the shell fragment inside the second floating body 104 attraction under can be bonded to each other to be formed
Path, whole equipment normal work, after water level is too high, when the second floating body 104 floats upwards, privates 1014 and the 5th are led
Line 1015 is disconnected, and automatically controlled signal is delivered into control device, and control whole equipment is stopped；When water level reduces, second
Floating body 104 is floated downwards, and after the second floating body 104 slips down to default position, the shell fragment and the 5th on privates 1014 is led
It is bonded again under the attraction of magnet of the shell fragment inside the second floating body 104 on line 1015, and forms path, whole equipment is again
Start work.
It should also be noted that, the liquid-level switch also has another situation, as certain IC all the way of control device
(integrated circuit, integrated circuit, being a kind of microelectronic device or part) burns, and can give solenoid valve, under
First ball float in face loses effect, and at this time the second ball float controls the power-off of magnetic valve, also plays the effect of protection.
In the present embodiment alternative, the first floating body 103 and the second floating body 104 are disposed as cyclic structure, the first floating body
The internal diameter of 103 internal diameter and the second floating body 104 is all higher than the external diameter of the body of rod 101；
And first floating body 103 internal diameter and the internal diameter of the second floating body 104 be respectively less than the external diameters of barriers 102.
Wherein, the first floating body 103 and the second floating body 104 may be configured as hollow-core construction or other structures, as long as can make
One floating body 103 and the second floating body 104 are floated in water, therefore are not just repeated one by one.
Specifically, the body of rod 101 is metallic rod body 101, the first floating body 103 and the second floating body 104 are metal floating body；Using
During, conductor can be played a part of.
To the liquid-level switch of the present utility model being described in detail as can be seen that the present embodiment provides, including bar with reference to more than
Body 101, the body of rod 101 divided for two-part barriers 102；The Part I of the body of rod 101 is arranged with for controlling water level height
