Abstract

The invention relates to a button. The button comprises a baseplate, a button cap, cover plate and a supporting device. The cover plate is arranged above the button cap and is made of magnetic materials. The supporting device is arranged between the baseplate and the button cap and is respectively connected with the button cap and the baseplate in a rotating mode. The button cap has a first magnetic area, and the supporting device has a second magnetic area, wherein the position of the first magnetic area is corresponding to the position of the second magnetic area. When the button cap is not pressed, the magnetic attractive force between the first magnetic area and the second magnetic area enables the button cap to be kept in an unpressed position. When the button cap is pressed by external force, the button cap is moved from the unpressed position to a pressed position along with the supporting device. When the external force is released, the magnetic attractive force enables the first magnetic area to be close to the second magnetic area, so that the button cap can be moved back to the unpressed position from the pressed position along with the supporting device. The button utilizes the magnetic attractive force to enable the button cap to be shifted between the unpressed position and the pressed position along with the supporting device without installing elastic pieces, so the service life of the button can be effectively prolonged.

Description

technical field [0001] The present invention relates to a button, in particular to a button which utilizes magnetic attraction force to move the keycap along with the supporting device between a non-pressed position and a pressed position. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] see figure 1 , figure 1 It is a schematic cross-sectional view of a button in the prior art. like figure 1 As shown, the button 1 includes a bottom plate 10 , a keycap 12 , a circuit board 14 , a supporting device 16 and an elastic member 18 . The circuit board 14 is disposed on ...
