Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
Please refer to Fig. 1~4, in the embodiment of the present invention, a kind of magnetic attracting construction of switch, including switch case 1 and pressing
Block 2, the bottom of the switch case 1 opens up switch slot 14, offers pressing hole 13 on the top surface of the switch case 1, described
Sliding card sets briquetting 2, the fixed contact button block 20 in the top of the briquetting 2, the contact button in switch slot 14
Block 20 is threaded through in pressing hole 13, and the bottom of the briquetting 2 is equipped with conductive metal layer 22, and the conductive metal layer 22 is located at outer
Right above portion's switch contact component, the inner top surface plate of the switch case 1 is set as magnet layer 12, and the top surface of the briquetting 2 is set
It is set to magnetic metal block 21；
The contact button block 20 is made of insulating materials, and insulating materials can guarantee in face contact button block 20,
Hand electric shock；
The whole height of the contact button block 20 is greater than the spacing of 22 bottom surface of conductive metal layer and 1 bottom surface of switch case,
Principal security contact button block 20 will not be when 2 entirety of pressing briquetting moves down, and contact button block 20 is inadequate due to length
It is pressed into switch slot 14 and the case where blocking contact button block 20 occurs；
The magnet layer 12 be permanent magnetic iron, magnet layer 12 can the magnetic metal block 21 to bottom upward magnetic force is provided
Attract, the magnetic metal block 21 is irony plate, and irony plate can preferably guarantee 12 pairs of magnetic metal block 21 of magnet layer
Attraction；
The switch slot 14 is circular groove, circular groove, four sides arc, the upper downslide in switch slot 14 in briquetting 2
Briquetting 2 can be largely reduced in dynamic process and switchs the rigid friction of 14 inner wall of slot；
The external switch contact component includes connecting plate 3, and the top of the connecting plate 3 is equipped with connection switch contact 30,
The underface of briquetting 2 is protruded into switch slot 14 and be located in the connection switch contact 30, and the left and right sides of the connecting plate 3 is logical
Excessive root fixed screw 31 is screwed with the bottom edge of switch case 1 to be connected.
The working principle of the invention is: when the connection switch that switch case 1 and 2 integral installation of briquetting are arranged in outside
When on contact 30, contact button block 20, conductive metal layer 22 and 30 phase of connection switch contact of 2 bottom of briquetting are pressed down on
Contact, 30 both ends circuit communication of connection switch contact closes the switch；When unclamping contact button block 20, magnetic metal block 21
It can be moved upwards automatically in the case where the magnetic force of magnet layer 12 attracts, and finally be pull-in on the inner bottom surface of switch slot 14, as a result, briquetting
The conductive metal layer 22 of 2 bottoms and connection switch contact 30 disconnect, and switch disconnects, and switch case 1 is attracted by magnetic force as a result,
Mode realizes the automatic rebounding of conductive metal layer 22, designs instead of the previous rebound by spring, solves previous bullet very well
The decline of loss elastic force, contact button block 20 can not spring back, be easy stuck problem spring for a long time, substantially increase switch case 1
On-off times, reduce 1 contained spring of switch case Auxiliary support setting, improve switch whole service life it is same
When, the cost of manufacture of switch is decreased, can apply in multiple fields such as snap switch, keyboard buttons, there is very big city
Field prospect.
