Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
As shown in figure 1, the utility model is a kind of waterproof overturning-preventing electronic switch, including shell, shell are transparent material,
It is easy to repair in the position of convenient observation inner body.Shell is divided into 4 three spheroid chamber 2, connecting portion 3, switch cavity parts, wherein
The top of spheroid chamber 2 is provided with the first buckle 101, and screw 102 is respectively equipped with the both sides of connecting portion 3, and screw use is provided with screw 102
In switch is fixed on other objects, the latter half of each screw 102 has rib connection and spheroid chamber 2, is opened for increasing
The mechanical strength of pass；The side of switch cavity 4 is provided with the second buckle 103, and there is several and fine motion electronic switch unit the lower section of switch cavity 4
404 terminals 104 being connected.
The bottom of connecting portion 3 is additionally provided with a position retaining plate, and position retaining plate is provided with the hole to match with the size of terminal 104, gear
On the position that the terminal 104 that plate is positioned over connecting portion 3 stretches out, further sealed spheroid.
As shown in Figure 2 and Figure 3, wherein Fig. 3 is Fig. 2 dotted portion enlarged drawings, and the inside of spheroid chamber 2 is the cavity structure of spheroid,
A metal ball 201 is provided with spheroid chamber 2.
The connecting portion 3 has the ball support 301 for support metal ball 201, and the bottom of ball support 301 is embedded in lever shrapnel
In 304 hole, spring 302 is installed between ball support 301 and lever shrapnel 304, the part of lever shrapnel 304 is located at connecting portion 3
Interior, another part is located in switch cavity 4；Connecting portion 3 is boundary with card rib 303 with switch cavity 4, and card rib 303 is used to limit lever
The position of shell fragment 304.
The switch cavity 4 is cavity structure, and lever shrapnel 304 is located at the part in switch cavity 4, its end and hinge hole
401 are hinged, downside that the close hinge hole 401 of lever shrapnel 304 goes out and be arranged on fine motion electronic switch unit 404 by
Key 402 is contacted, and the silica gel sealing set 403 for sealing is provided between the housing of button 402 and fine motion electronic switch unit 404；
