Embodiment two：
As shown in figure 12, the present embodiment and the main distinction of embodiment one are：The positioning sliding block 9' sides of the present embodiment
Also the stopper slot 91' in arc-shaped being caught in for the first balancing pole 81 and the second balancing pole 82 is offered, stopper slot 91' has
Be open 911', and opening 911' tops bend inwards to form raised 912' respectively with bottom.However, the raised 912' of the present embodiment
End face is not provided with angle, and the thickness of thin of positioning sliding block 9 of the positioning sliding block 9' of the present embodiment thickness ratio embodiment one.
Embodiment three：
As shown in Fig. 7, Figure 10, Figure 13, Figure 14 and Figure 15, the present embodiment and the main distinction of embodiment one are：By institute
State and lead the lower surface of core 3 and open up a grooving, this is led the lower surface of core 3 and is formed and some lead core salient angle 33.Meanwhile it is by two ways
Lead core salient angle 33 and provide and allow bit space, one way in which is：Confession is offered on the pedestal 1 and positioned at the outside of lead 11
Some slots to make way 16 that core salient angle 33 stretches into are led, and the depth of the slot to make way 16 is exactly equal to lead the height of core salient angle 33；It is another
Kind of mode is：Offered on the pedestal 1 and positioned at the outside of lead 11 for leading some resigning holes that core salient angle 33 passes through
16'。
In the present embodiment, the slot to make way 16, resigning hole 16' quantity are identical with leading the quantity of core salient angle 33,
In the present embodiment, the quantity for leading core salient angle 33 is 4, but leads core salient angle 33 it can also be provided that 2 or more, can be according to tool
Body needs and set.
Meanwhile the height for leading core salient angle 33 can be set according to specific needs, in the present embodiment, it is preferred that
The height for leading core salient angle 33 is 0.4mm.By leading core salient angle 33 and the matching design of slot to make way 16 or resigning hole 16', allow
Position groove 16 or resigning hole 16' keep away position as pedestal 1, make to lead the length of fit before mutually being slided between core 3 and pedestal 1 and lengthen,
Bite sense will not be produced by leading the pressing of core 3.Meanwhile the height of key switch is reduced, make key switch integral thickness thinner.
Operation principle of the present utility model is：
As shown in Figures 9 to 11, when press down on lead core 3 when, the inserting column 32 for making to lead core 3 inserts the pilot hole 12 of pedestal 1
In, the core salient angle 33 of leading for leading the lower end of core 3 is inserted in the slot to make way 16 or resigning hole 16' of pedestal 1, while makes the lead of pedestal 1
11 insertions are led in the annular slot 31 of core 3, and compression spring 7, and touching makes the still 51 of feed-through assembly 5 be in contact with moving plate 52, real
The conducting function of existing key switch；At the same time, first horizontal bar 811 and of the lower end of core 3 respectively to the first balancing pole 81 are led
Second horizontal bar 821 of two balancing poles 82 applies downward active force, and under the position-limiting action of positioning sliding block 9, the first balance
Bar 81 is swung up and down with the second balancing pole 82, keeps pressing balance.
As shown in Figure 6 to 8, when the active force that core 3 is led in pressing disappears, under the elastic restoring force effect of spring 7, lead
Core 3 resets upwards, and upper end passes the opening 21 of lid 2, returns to original position, at the same time, the still 51 of feed-through assembly 5
It is separated with moving plate 52, realizes the break function of key switch.
Emphasis of the present utility model essentially consists in：
(1) split type the first balancing pole and the second balancing pole built in, under the position-limiting action of two infall positioning sliding blocks,
The first balancing pole and the second balancing pole is set to swing up and down and reach pressing balance, pressing balance significantly carries with pressing stability
It is high；
(2) by leading core salient angle and the matching design of slot to make way or resigning hole, slot to make way or resigning hole keeping away as pedestal
Position, provides to lead core salient angle and allow bit space, make to lead between core and pedestal the length of fit before mutually slip and lengthen, lead core and press not
Bite sense can be produced；Meanwhile the height of key switch is reduced, make key switch integral thickness thinner；
(3) by the setting of torsion spring, enhancing pressing feel, pressing sound is sent.
It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made
Any restrictions, therefore identical with the utility model above-described embodiment or approximate technical characteristic is used, and obtained other structures,
Within the scope of protection of the utility model.
