Offer on plastic casing 2 by keyway 7, the spigot surface by keyway 7 offered the stroke groove 8 of two symmetrical rectangles, inside plastic casing 2 with by keyway 7 coaxial line and be close to the position of plastic casing 2 and offer a circle sealed groove 9；
Sealing ring 3 is the cylindrical rubber part of hollow, has ring-type upper sealing lip 10, ring-type lower seal lip 11；
Button 1 is installed to by keyway 7, and button axle coordinates with by the spigot surface of keyway 7, and the top of cantilever 6 coordinates with the upper surface of stroke groove 8, the upper sealing lip 10 banding button sealed groove 5 of sealing ring 3, lower seal lip 11 banding sealed groove 9.
This utility model still further comprises following preferred version:
Columned button axle is stretched out using the center of circle of the inscribed circle of the lower surface of the button cap of button 1 as center, the lower surface of button cap stretches out four elastic arms 4, described elastic arm 4 line centered by the axis of button axle, is uniformly distributed on 360 degree of circumference, and lower end bends laterally.
The bottom of described cantilever 6 is one-body molded with button axle, and top outwards dissipates, the symmetrical plane of two suspended walls 4 of deviation.
The free end design chamfering of button axle.
The downward through spigot surface in lower surface of described stroke groove 8, upper surface is the most through.
When button 1 is pressed, elastic arm 4, sealing ring 3 stress produce elastic deformation, and after removing the external force being applied on button 1, above-mentioned elastic deformation is recovered automatically, assist button 1 to reset；After button 1 resets, the top of cantilever 6 is resisted against on the upper surface of stroke groove 8, prevents button 1 from departing from by keyway 7.
This utility model has a following useful technique effect:
In this utility model, forming labyrinth structure by keyway 7 with plastic casing 2 outer surface, constitute first and seal, effectively resist moisture and enter inside plastic casing, sealing ring 3 can stop the moisture by the first seal structures, and two seals structure improves sealing property；
The top of cantilever 6 coordinates with the upper surface of stroke groove 8, can limit button 1 and rotate in by keyway 7, prevent button 1 from coming off in by keyway 7 simultaneously；
There is elastic deformation in elastic arm 4, sealing ring 3, after the external force that release is applied on button 1, elastic arm 4, the elastic deformation of sealing ring 3 disappear, and assist button 1 to reset when button 1 is pressed.

Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
In Fig. 1, press key sealing structure includes button 1, plastic casing 2, sealing ring 3；
Wherein the structure of button 1 is as shown in Figure 3, the top of button 1 is button cap, columned button axle is stretched out using the center of circle of the inscribed circle of the lower surface of button cap as center, the lower surface of button cap stretches out four elastic arms 4, described elastic arm 4 line centered by the axis of button axle, being uniformly distributed on 360 degree of circumference, lower end bends laterally.Two symmetrical cantilevers 6 are set at the middle part of button axle, the bottom of cantilever 6 is one-body molded with button axle, top outwards dissipates, the symmetrical plane of two cantilevers 6 of deviation, the envisaged underneath one of the bottom being positioned at cantilever 6 on button axle encloses sealed groove 5, and the free end at button axle designs chamfering simultaneously.
As shown in Figure 4, plastic casing 2 being offered by keyway 7, the spigot surface by keyway 7 is offered the stroke groove 8 of two symmetrical rectangles, the downward through spigot surface in lower surface of stroke groove 8, upper surface is the most through；Inside plastic casing 2 corresponding with by keyway 7 and be close to the position inside plastic casing 2 and offer a circle sealed groove 9.
