Embodiment Construction

[0026] Below in conjunction with accompanying drawing and embodiment describe in detail:

[0027] 1. Overall

[0028] Such as figure 1 , the structure of this circuit is:

[0029] Including power supply 000;

[0030] A reed switch module 100, a debounce module 200 and a power switch module 300 are provided;

[0031] The power supply 000, the reed switch module 100, the debounce module 200 and the power switch module 300 are connected in sequence.

[0032] Its working principle is:

[0033] The voltage of the power supply 000 is input to the reed switch module 100, and the reed switch module 100 is controlled by a strong magnet outside to open and close the reed switch module 100, and the reed switch module 100 is output to the debounce module 200 to remove interference , the debounce module 200 outputs a control signal to control the power switch module 300, so as to control the power on and off through a strong magnet.

[0034] 2. Function block

Abstract

The invention discloses a magnetic switch circuit based on a reed pipe, and relates to a magnetic switch technique. The magnetic switch circuit comprises a power supply (000) and is provided with a reed pipe switch module (100), a shaking eliminating module (200) and a power supply switch module (300), and the power supply (000), the reed pipe switch module (100), the shaking eliminating module (200) and the power supply switch module (300) are sequentially connected. According to the magnetic switch circuit, a reed pipe is used as a switch device to replace a common button or key, not only is the circuit simple and reliable, but also fully-enclosed design can be achieved on the structure, and waterproofness can be effectively achieved.

Description

technical field [0001] The invention relates to a switch circuit, in particular to a magnetic switch circuit based on a reed switch. Background technique [0002] In the current electronic equipment, the switching devices are generally implemented by buttons or keys, which generally require opening holes in the structure, and it is difficult to achieve a waterproof design. The reed switch magnetic switch used in the present invention can be isolated from the reed switch by using a strong magnet as a switch device, and the structure does not need openings, and the waterproof design can be easily achieved. Contents of the invention [0003] The purpose of the present invention is to overcome the problems and deficiencies in the prior art, and provide a magnetic switch circuit based on a reed switch. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] ① Use the reed switch as a switch device to replace th...
