The raw essence of component 16 positioned at the lower section in the centre of keycap 12 and the first galianconism 184 and the second galianconism 204 adjacent to keycap 12 in
Length direction 12a side is set, and is staggeredly set in length direction 12a through the first balance bar 18 and the second balance bar 20
Put, the first balance bar 18 and the structure of the second balance bar 20 also can be different., can be according to being described above in practical operation, first is flat
Weighing apparatus 18 and second balance bars 20 of rod member are variable to dissolve different configurations, does not repeat separately.
In addition, each figure shows that the first galianconism 184 and first long-armed 186 length are only to illustrate, in practical operation, first is short
The position that the length of arm 184 and first long-armed 186 can pass through corresponding first galianconism 184 and first long-armed 186 of keycap 12 is used to have
Imitate the amount of moving down needed for trigger switch 222 and determine.If such as middle part (phase of keycap 12 of the embodiment shown in corresponding diagram 1
When producing component 16, first long-armed 186 position in corresponding restoring force) need to move down 2.00mm begin can effective trigger switch 222, and
When the amount of moving down that the left side position of keycap 12 is allowed (equivalent to the position of corresponding first galianconism 184) is 1.80mm, first is long-armed
186 length may be designed as 2.00/1.80 times of the length more than or equal to the first galianconism 184.If also, and consider practical operation
For keycap 12 caused by the fit tolerance of each inter-module of middle press-key structure 1 when side is pressed, other positions of keycap 12 are not
Can make same amount it is mobile the problem of (i.e. keycap 12 can not move down to keep level) when, first long-armed 186 length is short to first
The multiple of the length of arm 184 may be designed as significantly greater than 2.00/1.80 times, to compensate this amount of moving down difference.Set in actual product
In meter, the Design of length of the first long-armed 186 and first galianconism 184 can be based on foregoing principle can be obtained after simple trial it is suitable
Suitable length value.Mentioned length design principle is also applicable to the second galianconism 204 and second long-armed 206 Design of length, no longer
Repeat.
In addition, and refering to the side view of the first balance bar 18 shown in Fig. 8, head rod 182, first can be observed
Galianconism 184 and first long-armed 186 is non-coplanar, and this structure is suitable to the overall keycap 12 that substantially still keep level state is set.Principle
