Embodiment
In order to more clearly state the utility model, the utility model is further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model discloses a kind of detachable button switch, including upper lid 1, shell 2, metal key-press 3
With base 4, upper lid 1, shell 2 and base 4 enclose a closed cavity, and metal key-press 3 is contained in closed cavity, wherein,
Shell 2, which is embedded in, is provided with inner casing 5, and the support frame of support metal key-press 3 is provided with inner casing 5, and metal key-press 3 passes through inner casing 5
On support frame support, be connected with base 4, and the sheet metal on metal key-press 3 connects through base 4 and pcb board (not shown)
Contact.In the present embodiment, metal key-press 3 is connected by spring 6 with upper lid 1, and spring retention post (figure is provided with upper lid 1
Do not show), one end of spring 6 is fixed on spring retention post, and the other end is contacted with metal key-press 3 by pressing upper lid 1, when by
In pressure after lid 1, metal key-press 3 is contacted with spring 6, and number of packages button 3 is squeezed, triggering deformation, and bottom is passed through on metal key-press 3
Sheet metal on seat 4 contacts with pcb board, and now, pcb board senses that the button switch of the position acts, so as to perform pair
The button switch action answered.
In the present embodiment, referring to Fig. 2, it can also be double-decker that upper lid 1, which can be independent integrative-structure, when to be double
