The position of the contact stud 22 of the position of contact 41 and multiple keys 2 corresponds, and the is equipped between contact head 41 and contact stud 22
Two gaps 40, wherein the distance in the first gap 10 is greater than the distance in the second gap 40.
In pressing keys cap 21, button cap 21 overcomes the elastic anchorage force of elastic arm 11 to move, and button cap 21 is synchronous to be pushed
The distance in the first gap 10 is gradually reduced, at the same contact head 41 and contact stud 22 move closer to make at a distance from the second gap 40 by
It is tapered small, since the distance in the first gap 10 is greater than the distance in the second gap 40, when contact head 41 touches contact stud 22, the
The distance in two gaps 40 is zero, and touch-switch 4 is touched and starts to work at this time, and button cap 21 continues to push, in touch-switch 4
Metal dome start to deform, until the upper-end contact of the lower end of button cap 21 and limiting section 12, the at this time distance in the first gap 10
It is zero, limiting section 12 withstands button cap 21 to prevent the downward motion of button cap 21, even at this point, the receiving of button cap 21 is very big
Continuous or when greater impact power, button cap 21 will not further downward motion, so as to avoid touch-switch
Internal metal dome, which is pressurized, exceeds its elastic deformation range, and can not bounce after causing touch-switch to be pressed, and then make to touch out
It closes 4 and generates the case where functionality fails.
Preferably, the distance in the first gap 10 is 0.5-0.8mm, and the distance in the second gap 40 is 0.2-0.3mm.This range
Gap the feel and Experience Degree of pressing can be improved, while can also can guarantee that the metal dome in touch-switch 4 is in parallel
One reasonable range.
As shown in connection with fig. 2, key main body 1 is equipped with positioning column 13, and pcb board 3 is equipped with corresponding with 13 position of positioning column
Location hole 31, positioning column 13 accordingly passes through location hole 31；The connection of positioning column 13 and location hole 31 can by pcb board 3 into
Row accurately positioning, it is ensured that the contact head of the touch-switch 4 on pcb board 3 can be aligned always with contact stud 22.
Preferably, a side wall of key main body 1 is equipped with spliced eye 14, and a side of pcb board 3 is equipped with and spliced eye
The corresponding grafting block 32 in 14 positions, grafting block 32 are accordingly plugged in spliced eye 14；It can ensure on pcb board 3 in this way
The second gap 40 between the contact head and contact stud 22 of touch-switch 4 is able to maintain a more stable value range always,
It is bad to touch 4 face contacts of opening the light.
Identical in order to solve the problems, such as, the utility model additionally provides a kind of speaker, including touching for any of the above-described scheme
Switch block.
In conclusion the press-key structure of the utility model embodiment, in pressing keys cap 21, button cap 21 overcomes elastic arm
