Embodiment 1

[0052] Please refer to Figure 1 to Figure 3 , the present embodiment provides an ultra-thin mechanical key switch, including a base 1 , a cover 2 disposed above the base 1 , and a balance frame 3 disposed between the base 1 and the cover 2 . The key switch of this embodiment also includes a movable body 4 arranged between the base 1 and the cover 2 and driven up and down by the balance frame 3, a conduction trigger A5 arranged on the movable body 4, and electrically connected to the circuit board and a conduction trigger B6 corresponding to the conduction trigger A5, usually, the circuit board is arranged under the base 1, and the base 1 can be welded to the circuit board through the solder feet at the bottom, of course, it can also be Corresponding buckles are set on the base 1 and buckled on the PCB board. In this embodiment, the movable body 4 is an elastic structure, preferably an elastic sheet.

[0053] In this embodiment, one end of the movable body 4 has an active se...

Embodiment 2

[0060] Such as Figure 15 to Figure 22 As shown, the main difference between this embodiment and Embodiment 1 is that a sound-emitting elastic body 7 is arranged between the base 1 and the cover 2, and the sound-emitting elastic body 7 can be made of plastic or metal, specifically, it can be a shrapnel or Elastic steel wire, the accompanying drawing of this embodiment uses the sound-emitting elastic body 7 as a shrapnel as an example for illustration. The sound-emitting elastic body 7 (shrapnel) of this embodiment is driven by the cover 2 to deform and rebound and hit the cover 2, the base 1 and / or The gimbal 3 makes a sound.

[0061] In this embodiment, in order to cooperate with the sounding of the sounding elastic body 7, a bump 30 located below the sounding elastic body 7 is protruded on the balance frame 3, and when the sounding elastic body 7 is turned downward and deformed, the sound will be produced. In addition to hitting the base 1 to make a sound, the elastic body ...

Abstract

The invention discloses an ultrathin mechanical key switch. The ultrathin mechanical key switch comprises a base, a cover and a balancing rack and also comprises a movable body, a conduction trigger piece A and a conduction trigger piece B, wherein the cover is arranged on the base, the balancing rack is arranged between the base and the cover, the movable body is arranged between the base and thecover and drives the balancing rack to move upwards and downwards, the conduction trigger piece A is arranged on the movable body, and the conduction trigger piece A is electrically connected to a circuit board and is corresponding to the conduction trigger piece A. With the ultrathin mechanical key switch provided by the invention, the press balance and the press hand feeling can be improved, moreover, the ultrathin mechanical key switch is thin in integral thickness, and thinness is favorably achieved.

Description

technical field [0001] The invention relates to a key switch, in particular to an ultra-thin mechanical key switch. Background technique [0002] As various electronic devices continue to be thinner and thinner, the key switches used in the electronic devices also need to be made thinner and thinner. Such as ultra-thin notebook computer, in order to make the notebook computer can reach the ultra-thin standard, the key switch on the notebook computer keyboard must be done relatively thin, also must guarantee its performance and feel at the same time. [0003] Generally, when the keycap is pressed down on a mechanical key switch, a corresponding guide core needs to be provided to trigger the contact conduction between the moving contact piece inserted in the base and the static contact piece. The space for accommodating guide core, moving contact piece and static contact piece. At the same time, in order to meet the demand for hand feel, it is necessary to add a correspondin...
