The ultra-thin touch key switch that the present embodiment is provided, small volume is a can to apply to smaller use space
In touch key switch, with closing, keycap can be used.
Operation principle of the invention is：As shown in Fig. 2 touch key switch is in the raw, and now, feed-through assembly 2
The middle part of electroconductive elastic sheet 22 do not contacted with the middle stationary contact 212 of still 21, therefore, touch key is switched and is off；Match somebody with somebody
Close after keycap, as long as pressing down on keycap, above lead core 5 and be subject to downward active force with X-type balancing stand 4 and move down, led upper
In the folding process of core 5, core 3 is led to silica gel and applies active force, silica gel is led core 3 and be squeezed and deform, so that silica gel is led
Core 3 drives the deformation of the middle part of electroconductive elastic sheet 22 recessed, the middle part of electroconductive elastic sheet 22 is contacted with the middle stationary contact 212 of still 21, then gently
Touch key switch is in the conduction state；When release is to above leading the downward active force of core 3 and X-type balancing stand 4, core 3 is led in silica gel
Elastic restoring force effect under, silica gel lead on core 3 move return to nature during, led in drive on core 5 move, above lead
Core 5 is driven by upper guidance axis 51 and moved on X-type balancing stand 4 during upper shifting, recovery to nature, then touch key
Switch recovers to off-state.
Emphasis of the invention is essentially consisted in：
(1) by using overall X-type balancing stand in all round closure type structure, on lead core and lead core and pedestal matching with silica gel
Cooperation is used, and when pressing force disappears, leads core using silica gel to lead shifting on core on driving, then led from above on the dynamic X-type balancing stand of core ribbon
The mode of shifting, the space for making full use of touch key switch internal limited, for the process of pressing up and down of touch key switch is provided
Counteracting forces, equilibrium function is remarkably reinforced, and more preferably, stationarity is stronger for counterbalance effect, and resistance to overturning is improved, meanwhile, make light
Touch key switch internal structure realizes every power energy；
(2) the single upper lid of tradition is divided into big fixture block and small fixture block, silica gel is led between core outer side edges and big fixture block and silicon
Glue to be led and form slot to make way respectively between core outer side edges and small fixture block, and bit space is allowed for the lower embedded division of X-type balancing stand provides activity,
Beneficial to the pressing stability of equilibrium for improving touch key switch.
The above, is only presently preferred embodiments of the present invention, and not technical scope of the invention is imposed any restrictions,
Therefore technical characteristic identical with the above embodiment of the present invention or approximate is used, and the other structures for obtaining, in guarantor of the invention
Within the scope of shield.
