Under the general operating position; Because button 70 possesses flexible; Therefore accepting external force when button 70 tops presses downwards when touching; Torsional deformation and touch beam barrel 30 and move down downwards causes beam barrel 30 bottoms to push away to touch electroconductive elastic sheet 40 and removes to contact said positive and negative electrode 21,22, makes said positive and negative electrode 21,22 through these shell fragment 40 mutual conduction.
Touch the external force disappearance of button 70 and beam barrel 30 when pressure after, the elastic force of this shell fragment 40 can drive beam barrel 30 and reset with button 70, and cuts off said positive and negative electrode 21,22.
In addition; This light-emitting diode 60 can be accepted the metallic circuit power supply of circuit board and emits beam via said positive and negative electrode pin 61,62; And the light of light-emitting diode 60 can be issued to the external world via button 70, learns the position and the user mode of switch with the prompting user.
What deserves to be mentioned is that this button 70 can cover storage tank 11 via ring rib 71, infiltrate storage tank 11 to block extraneous aqueous vapor or liquid, and prevent that said electrode group 20, electroconductive elastic sheet 40 in the storage tank 11 from producing corrosion phenomena with light-emitting diode 60.
In view of the above; The utility model can utilize light-emitting diode 60 to produce light source, and utilizes button 70 to cover storage tank 11, to overcome in the above-mentioned prior art; The inside of tradition touch-switch is atmosphere opening to external world directly; And make aqueous vapor or extraneous liquid in the atmosphere get into switch inside easily, cause problems such as the bad or damage of switching manipulation, and then promote the durable useful life of switch.
Below further specify other execution modes of the utility model:
These pedestal 10 periphery walls form two symmetrical hook parts 13; These button 70 peripheral sheathed ferrule pieces 50; And the ring rib 71 that makes these button 70 periphery walls is held between said ring 50 and the anchor ring 12; And 13 directions extend to form the two symmetrical first frame sheets 51 to ring 50 periphery toward hook parts, form one on this first frame sheet 51 and can buckle the slot part 511 of being located at hook part 13; So, can hold button 70 in pedestal 10 tops, and closely holding ring rib 71 and makes said ring 50, encircles tool watertightness between rib 71 and the anchor ring 12 between said ring 50 and anchor ring 12 through ring 50 button.
These ring 50 central authorities are formed with one can be sheathed on the peripheral port 53 of button 70, and ring 50 peripheries extend to form the two symmetrical second frame sheets 52 toward pedestal 10 directions, and these pedestal 10 perisporiums are positioned between the said first frame sheet 51 and the second frame sheet 52.
This ring rib 71 bottoms form one and are positioned at the peripheral annular groove 72 of storage tank 11, and form on the anchor ring 12 one can embed annular groove 72 bulge loop 14; So, can promote watertightness between said ring rib 71 and the anchor ring 12 more.
It is two symmetrical and be communicated with the guide channel 32 of this groove 31 that these beam barrel 30 periphery walls form, and guide channel 32 extends to a notch 311 of a groove 31, and the said positive and negative electrode pin 61,62 of this light-emitting diode 60 extends to pedestal 10 bottoms via this guide channel 32 respectively; So, when beam barrel 30 is driven by external force and during moving back and forth, can be via the guide channel 32 said positive and negative electrode pin 61,62 of dodging.
These beam barrel 30 periphery walls form two symmetrical protuberances 33, accept said ring rib 71 backstops respectively, and it is mobile in storage tank 11 in to make ring rib 71 restrain beam barrels 30.
These shell fragment 40 rounded convex arc-shapes; And make shell fragment 40 periphery contact negative electrodes 22, these shell fragment 40 middle bodies break away from positive electrode 21, when this beam barrel 30 is accepted the external force driving via button 70; Can push away and touch shell fragment 40 middle bodies contact positive electrode 21; And shell fragment 40 is connected in positive and negative electrode 21,22, and shell fragment 40 middle bodies elastic reset after the external force that drives beam barrel 30 disappears, and break away from positive and negative electrode 21,22.
The groove 73 of one corresponding storage tank 11 is formed on these button 70 bottoms, and beam barrel 30 tops embed in the groove 73.
In addition; Because the button 70 processed of silica gel has resistant to elevated temperatures characteristic, so button 70 can get into the tin stoves along with beam barrel 30 and pedestal 10, and needn't be as traditional approach after the pedestal of switch has been crossed the tin stove; Load onto button in beam barrel again, can further practice thrift technology.
Moreover this button 70 possesses resilient flexible, can effectively cushion prominent next impulsive force, to promote the durable useful life that switch acceptance is pushed.
To sum up institute is old, is merely the preferred embodiment of the utility model, is not in order to limit the utility model; All other do not break away under the spirit that the utility model discloses and the equivalence of accomplishing is modified or displacement, all should be contained in the scope of patent protection of the utility model.
