Embodiment

At first please cooperate and consult Fig. 1 to shown in Figure 4, the utility model is a kind of key switching structure of control panel, and it comprises: a keycap 10, a draw key 20, a positioning seat 30, a protective sleeve 33 and a control panel 40;

Wherein, this keycap 10 is a keyboard switch press element, be embedded assembling word original text plate 15 and draw key 20 in regular turn in these keycap 10 bottoms, wherein these word original text plate 15 ora terminalis are concaved with a perforation 16, penetrate leaded light in this keycap 10 for light source, and these draw key 20 top board ora terminalis also are concaved with a perforation 21 and penetrate for light source, and protruded out a hollow downwards by compression leg 25 in the bottom surface of these draw key 20 top boards, and this be arranged in the axis hole 31 of positioning seat 30 by compression leg 25 correspondences, and by the bottom build-in of compression leg 25 trip 35 is arranged in this hollow, pull and hold 36 then to contact in regular turn in a silica gel sheet 56 and a sensitive switch 61 downwards in the top of these trip 35 bottoms, and it pushes elastic reset and signal conduction function so that this to be provided by compression leg 25 by the sensitive switch 61 on the circuit board 60, as for 30 spiral shells of this positioning seat if the cover be fixed in the circular hole 42 of control panel 40, and these positioning seat 30 bottoms are behind a sheathed packing ring 55, and it is fixed at a nut 50, be equipped with scarfing slot 32 in these positioning seat 30 perimeter side walls, as for 33 of this protective sleeves is the fit element of the dustproof antiseepage of a soft materials, and be equipped with interlocking flange 34 corresponding to scarfing slot 32 places of this positioning seat 30 in these protective sleeve 33 madial walls, so that this protective sleeve 33 is able to and this positioning seat 30 chimeric one that are assembled into, in the hope of reaching the effect of the dustproof antiseepage of protecting key switch;

Then, these control panel 40 end faces are assembled with a leaded light post 43, luminous element 62 light sources on the circuit board 60 being directed to this keycap 10 by this leaded light post 43, wherein be arranged with an antiseepage packing ring 55 in the circular hole 42 bottom side edge of this

control panel

40 and 51 of the apical rings of this nut 50, and on the bottom part ring edge 52 of this nut 50, installed an antiseepage silica gel sheet 56, can avoid liquid flooding to infiltrate in the switch element, in the hope of the antiseepage and the moistureproof effect that can further reach switch element;

Relevant main improvement structural feature of the present utility model and the actual effect of using thereof; then explain the main points briefly as after; the key switch structure-improved that is the utility model control panel is mainly rabbeted the fit element that is assembled with a dustproof antiseepage in the periphery of button positioning seat 30; the protective sleeve 33 that one soft transparent is promptly arranged in the scarfing slot 32 corresponding build-ins of these positioning seat 30 peripheries; then directly push these protective sleeve 33 surfaces when manipulating and get final product touch switch (as shown in Figure 4); directly contact in the hope of the keycap 10 of avoiding button with finger; and then reach antiseepage dustproof effect; and the useful life of increase button; moreover; this protective sleeve 33 directly is embedded fast and is assembled in this positioning seat 30 peripheries; so the utility model not only specifically improves the assembling that protective device caused of existing key switch and the numerous and diverse program in the dismounting; and integral assembling structure of the present utility model is extremely simplified, and can specifically reduce manufacturing cost.

Please consult Fig. 5 and shown in Figure 6 again; it is another embodiment of the dustproof fit element of the utility model key switch; and its fit element belongs to one and has hard over cap 70 structure that can lift opening plate 74; having one in these over cap 70 bases cooperates corresponding build-in in the through hole 78 of these positioning seat 30 peripheries; and be provided with interlocking flange 72 corresponding to scarfing slot 32 places of this positioning seat 30 in these through hole 78 madial walls; so that this over cap 70 is able to and this positioning seat 30 chimeric one that are assembled into; be pivoted with a cover plate 74 in these over cap 70 end face elasticity in addition; be equiped with a torque spring 76 in its position that is pivoted; so that this cover plate 74 is able to after raising; but elastic force with auto-closing; and make this over cap 70 have dustproof and avoid the use effect of improper mistake button cap; and the package assembly that this over cap 70 and positioning seat are 30 is extremely simplified, and can reach the usefulness of expection protection key switch.

In sum, the key switch of the utility model control panel specifically improves the shortcoming of existing key switch, and it has raising key switch packaging efficiency and increases the effect that its key switch is operated smooth and easy and dustproof antiseepage.
