Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment 1:
Shown in Fig. 2,3, the key device of present embodiment comprises circuit board 1, is installed in key support 3, key switch 4 and indicator light 5 on the circuit board, and the wherein above-mentioned key switch 4 and indicator light 5 outsides are provided with the active key device.
Above-mentioned active key device comprises the active key 2 of hollow and the annular key base 31 that injects with key support 3 one.
Above-mentioned active key 2 one sides are provided with rotating shaft 22, opposite side is provided with buckle 23, corresponding key switch 4 positions, its lower end are provided with the convex 21 that touches the key switch break-make, and above-mentioned annular key base 31 1 ends are provided with the axis hole 32 that cooperates with rotating shaft 22, and the other end is provided with the draw-in groove 33 that cooperates with buckle 23.
In the present embodiment, above-mentioned active key 2 is made by the transparent PP material.
When the utility model uses, press active key 2 downwards, buckle 23 moves down along draw-in groove 33, drives convex 21 and makes key switch 4 conductings, and indicator light 5 is bright, and light evenly sees through the top of transparent push 2, makes whole button uniformly light-emitting.
Embodiment 2:
The key device of present embodiment is shown in Fig. 4,5.Wherein, the lower end of above-mentioned active key 2 is provided with three card bases that extend downwards 24, three outward extending spacing convexes 25 of level and is used to touch the projection 211 of key switch 4 break-makes.Other structure is identical with embodiment 1.
During the present embodiment assembling, button leg 24 is aimed at key base 31 inner chambers to pressing down, button leg 24 stressed generation slight deformation, get in the key base 31 and be stuck in key base 31 lower edge places, spacing convex 25 holdings limit the position of active key 2 at key base 31 upper end-face edges, distance between leg 24 and the spacing convex 25 is a bit larger tham the height of key base 31, makes button 2 can touch key switch 4 so that enough displacements to be provided.
