Problems solved by technology
But when the water level drops, because the two magnetic steels are in the state of adsorption, the floating ball of the boom cannot drop smoothly with the drop of the water level, so its control is not precise enough and its work is not reliable enough

Embodiment Construction
[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0028] Such as figure 1 and 2 As shown, a float switch includes a base 1 and a cover 2. The base 1 is provided with a micro switch seat 8, and the micro switch seat 8 is fixedly connected with a micro switch 3, which has the advantage of convenient connection. A toggle lever 4 is arranged in the cavity of the outer cover 2, and the toggle lever 4 is bent, and one end of the toggle lever is hinged on the outer cover 2. The micro switch 3 can adopt the micro switch 3 whose application number is 201220254704.8 or the micro switch 3 whose application number is 201420254025.X.
[0029] The base 1 is vertically provided with a guide cylinder 1a with its opening facing downwards. A suspender 5 is movably connected to the guide ...

The invention provides a novel floating switch, which belongs to the field of mechanical technology and solves the problems that the existing floating switch has a complicated structure and the control precision is not high. The novel floating switch comprises a base and an outer cover, wherein the cavity of the outer cover is internally provided with a microswitch and a shifter lever; one end ofthe shifter lever is hinged on the outer cover; a hanging rod is movably connected onto the base; the lower end of the hanging rod is fixedly connected with a floating ball; the upper end of the hanging rod is connected with the shifter lever; the upper end of the hanging rod is fixedly connected with a magnetic steel; the other end of the shifter lever is fixedly connected with a magnetic steel;positions of the two magnetic steels are corresponding; when the two magnetic steels are pulled in, the shifter lever can push a button of the microswitch; the base is vertically provided with a guidecylinder with a downward opening; the upper end of the hanging rod is embedded in the cavity of the guide cylinder; and a thrust spring is arranged between the upper end of the shifter lever and theguide cylinder. The novel floating switch has the advantages of accurate control and reliable operation.
Description
technical field [0001] The invention belongs to the technical field of machinery and relates to a float switch, in particular to a novel float switch. Background technique [0002] When the water pump is working, it needs to be automatically controlled. When the water level reaches the upper or lower limit, it will stop working automatically. When pumping water to the reservoir, when the water level rises to the predetermined high water level, if the water continues to be delivered, the water will overflow the reservoir, resulting in a waste of a lot of fresh water resources; when doing drainage work in the reservoir, when the water in the reservoir is pumped When it is finished, it will cause the water pump to run idly, which not only wastes electric energy, but also makes the water pump chamber short of water. When the water pump is used again, it will refill the water, which is troublesome to operate. [0003] In order to solve this problem, some water pumps on the marke...
