Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1-3 are referred to, this utility model provides a kind of technical scheme：A kind of keyboard key axle switch, including base 1, institute
The middle part for stating base 1 is provided with axial trough 3, and axial trough 3 is used to provide space for the activity of key axle 2, and the bottom of the axial trough 3 is provided with stationary contact bar
4, stationary contact bar 4 is used to coordinate the switch of movable feeler lever 12 to use, and the upper end of the stationary contact bar 4 is provided with pressing plate 5, the stationary contact bar 4 it is upper
The lower end of end and pressing plate 5 is connected by resilient sleeve 6, and pressing plate 5 and being equipped with for resilient sleeve 6 are touched for completely cutting off stationary contact 8 and moving
Point 10 is provided with quiet permanent magnetic iron block 7 with extraneous directly contact, the upper surface of the stationary contact bar 4, and the upper end of the quiet permanent magnetic iron block 7 sets
The lower surface for having stationary contact 8, the pressing plate 5 is provided with being equipped with for dynamic permanent magnetic iron block 9, quiet permanent magnetic iron block 7 and dynamic permanent magnetic iron block 9
For making stationary contact 8 and movable contact 10 in the case of nature in released state, the lower end of the dynamic permanent magnetic iron block 9 is provided with dynamic touching
Point 10, the outside of the stationary contact bar 4 is cased with spring 13, and spring 13 is used to make movable feeler lever 12 reset, and the upper end of the spring 13 sets
The rear surface for having keyboard key axle 2, the keyboard key axle 2 is provided with feeler lever chamber 11, and the bottom in the feeler lever chamber 11 is provided with movable feeler lever
12, the inside that movable feeler lever 12 is used to make movable contact 10 move down the contact closure switch of stationary contact 8, the base 1 and stationary contact bar 4 is all provided with
There is threading hole 14, threading hole 14 is used for being connected into and picking out for wire.
Specifically, the resilient sleeve 6 is made up of antimagnetic material, and the resilient sleeve 6 of antimagnetic material can prevent quiet permanent magnetic iron block 7
