And as shown in Fig. 2, the connecting portion for leading 301 upper end of core main body and keycap linkage section 302 is provided with step structure 36.
As shown in Fig. 2, Fig. 5, this static 50 has the first installation base plate 51 and is connected on the first installation base plate 51
First pin 52 is connected with the first contact portion 53 on first installation base plate 51；The movable contact spring 60 has the second installation base plate 61
With the second pin 62 being connected on the second installation base plate 61, it is connected on second installation base plate 61 and is driven elastic arm, it should be by
It drives and is connected with the second contact portion 63 on elastic arm；The first mounting groove 23, the second mounting groove 24 are respectively arranged in the pedestal 20, it should
First mounting groove 23, the second mounting groove 24 all have upper end opening, and aforementioned first installation base plate 51, the second installation base plate 61 are from phase
The upper end opening answered respectively tightly embedded in the first mounting groove 23, the second mounting groove 24 to reach static 50, movable contact spring 60 is in pedestal
Assembly on 20 is fixed；And the first relief hole 25, the second relief hole 26 are offered on the pedestal 20 respectively, aforementioned first draws
Foot 52, second pin 62 are each passed through corresponding first relief hole 25, the second relief hole 26 is exposed to outside pedestal 20；It is assembling
When, directly by static 50 and movable contact spring 60 separately down compact imbeding pedestal 20, simplify static 50, movable contact spring 60
Especially movable contact spring 60 greatly reduces the automatic of entire mechanical keyboard switch in package assembly and assembling processing procedure in pedestal 20
Change installation difficulty, improve the Automated assembly of product, improve assembly efficiency and assembling quality, strengthens product and stablize
Property.
As shown in Fig. 5, Fig. 6 and Figure 11,10 bottom of upper cover is concave up equipped with corresponding with aforementioned second mounting groove 24
The upper section position of third mounting groove 16, the second installation base plate 61 is protruded into third mounting groove 16；The installation of first mounting groove 23, second
The opening of slot 24 and third mounting groove 16 is each formed with guiding face, convenient for static 50, the assembly of movable contact spring 60, also more easily
In upper cover 10, the molding making of pedestal 20；Wherein, the guiding face of third mounting groove 16 longitudinally extends longer, and upper cover 10 is blocked downwards
When buckle closure is together on pedestal 20,61 upper section of the second installation base plate of movable contact spring 60 more swimmingly enters in third mounting groove 16；Before
Stating the first mounting groove 23, the second mounting groove 24 and third mounting groove 16 is vertically extending long and narrow type groove, the size of slot
Substantially consistent or bigger with corresponding installation base plate, assembly positioning is more accurate, especially during subsequent applications, stability
More preferably.Herein, the surface of first installation base plate 51, the second installation base plate 61 is towards corresponding first mounting groove 23, second
24 inner wall of mounting groove be convexly equipped with for improving chimeric stable degree locking protuberance (54,64) as shown, specifically：Its locking is convex
(54,64) as shown are formed in the front and rear end of the first installation base plate 51, the second installation base plate 52 in portion（Such as：As shown in fig. 6,
