A kind of concrete scheme is, described button assembly and base joint are provided with gasket seal, and the sealing pad is socketed on the button assembly, and its edge is the covering base edge at least.
Described button assembly below is provided with the projection that play the guiding role, and the gasket seal correspondence position is provided with downward groove, and projection is placed in the groove, and this projection and base madial wall offset.
Another kind of concrete scheme is that described button assembly adopts soft material to make the sealing that realizes with base.
The open country is provided with the projection that play the guiding role below button assembly, and this projection and base madial wall offset.
Above-mentioned concrete scheme optimization scheme is that described cover plate extends to base end face along the base two relative side, converges at the base end face middle part and entangles base.
The concrete installing mechanism of cover plate and base is: the location hole both sides are provided with installing hole respectively on the described cover plate, on the corresponding base projection are set, base and cover plate socket, and two projections insert in the installing hole respectively; Described base end face also is provided with the guide vane end stop that is used for fixing cover plate, and guide vane end stop lays respectively at the base end face edge, and described cover plate is provided with screens at the base end face meet, and the clamping matching limited post blocks cover plate.Described gasket seal both sides all extend to the installing hole edge, cover the installing hole edge at least.
Compared with prior art, the present invention has following remarkable result: this switch is the side switch switch, and compact conformation, reliability height are applicable to ultrathin consumption electronic products such as mobile phone, MP4, digital camera; And hermetically-sealed construction is adopted in shift knob position and base joint, the base intracavity of switch is sealed fully, and when effectively avoiding switch and wiring board to cross Reflow Soldering, foreign matters such as rosin, dust infiltrate through switch inside, and avoid in the finished product use, dust enters and causes switch failure.

Embodiment
For the ease of it will be appreciated by those skilled in the art that the present invention is further described in detail below in conjunction with accompanying drawing and embodiment.
As Fig. 1,2,3,4, the impermeable miniature side switch switch that present embodiment disclosed comprises a base 1, a cover plate 2, and installing hole 21,22 is set on the cover plate 2, on the corresponding base 1 projection 11,12 is set, base 1 and cover plate 2 sockets, two projections insert in the installing hole respectively.
Shell fragment 4 and button assembly 5 are set in the base 1, and switch terminal 3 injection mouldings are on base 1, and wherein a terminal 31 is connected with two flanks that are arranged on the shell fragment 4 in the base.Button assembly 5 is located at shell fragment 4 tops.Location hole 20 is established in installing hole 21,22 middle parts on the described cover plate 2, and press section 51, button assembly 5 upper end is stretched out by location hole 20, and sheet 41 is suitable in button assembly 5 lower ends 52 and the shell fragment 4.The press section 51 of pressing button assembly 5, the middle sheet 41 of button assembly 5 lower ends compressing shell fragment 4 makes the another terminal 32 of its contact-making switch terminal 3, terminal 31 and terminal 32 conductings.
Be socketed with the gasket seal 6 that soft material (for example rubber) is made on button assembly 5, sealing pad 6 sizes are suitable with the base size, and gasket seal 6 edges cover bases 1 edge will be provided with the base intracavity sealing of button assembly and shell fragment.Gasket seal 6 belows are provided with downward groove 61, and this groove 61 is placed on the projection of button assembly 5 lower ends, and one arises from base 1 madial wall offsets, and plays the guide and limit effect.Gasket seal 6 both sides extend to installing hole 21,22 edges, and installing hole 21,22 edges cover are prevented from installing hole seepage foreign material.
In the present embodiment, cover plate 2 extends to base end face along base 1 two relative side, converges at the base end face middle part and entangles base.Cover plate 2 does not join at the base end face meet, and the slit is left in the centre, is convenient to the assembling processing of cover plate and base.Base 1 bottom surface is provided with the guide vane end stop 16 that is used for fixing cover plate, and guide vane end stop lays respectively at the base end face edge, and cover plate also is provided with screens 26 at the base end face meet in addition, and screens 26 cooperates limited post 16 that cover plate is blocked, and prevents that cover plate is loosening.Said structure helps gasket seal 6 and base 1 are compressed, and reaches better sealing effectiveness, also makes whole side switch construction of switch compact more simultaneously.
Of the present inventionly also can take another embodiment, be about to whole button assembly 5 and all adopt soft material to make, when the button assembly that soft material is made contacts with base, can be fully and base agree with, base intracavity is sealed, play sealing function.The projection of guide and limit effect has been set below the case assembly equally, and all the other structures of switch are also identical with embodiment one.
The preferred version that the foregoing description is realized for the present invention; and indefiniteness is exhaustive, and the present invention can also have other variations under same idea, need to prove; without departing from the inventive concept of the premise, any conspicuous replacement is all within protection range of the present invention.
