Because the integrated design of antenna module body 32 can reduce this car starting switch's whole volume, and its diameter can be less than 32mm, and length can be less than 50 mm.
The following describes the specific structure of the present automobile start switch in detail.
The antenna module body 32 is integrally formed by an insert injection molding process. The button 1 abuts against the upper end of the press switch assembly 2, and a shell 4 is arranged on the periphery of the antenna assembly module 3. The push switch assembly 2 includes an elastic member 21 and a PCBA board 22. As shown in connection with fig. 3, said push-button 1 comprises a main panel 11 and a guide 12; the main panel 11 is arranged at the upper end of the guide piece 12 and fixed together in a clamping manner; the outside of guide 12 is equipped with guide rib 121, the inboard of casing 4 is equipped with guide groove 41, guide rib 121 with guide groove 41 cooperation for guide 12 can reciprocate in the guide range of casing 4, prevents that guide 12 is rotatory relative to casing 4. The elastic part 21 may be integrally formed of elastic silicone rubber. The elastic part 21 is provided with an elastic arched part 211, and after the elastic arched part 211 is operated by pressing force, the elastic arched part 211 can be pressed downwards and can freely rebound after being released, so that the force and the displacement hand feeling of the button 1 are generated in the pressing process of the button 1.

When the elastic arched part 211 is pressed to contact the PCBA board 22 by the pressure of the button 1, the switch contact particles 212 contact two poles 221 of a switch contact loop on the PCBA board 22 to conduct the switch loop, and the switch loop sends an electric signal to the switch loop connector terminal 34; when the button 1 is released, the elastic arched part 211 rebounds, the switch contact particles 212 are separated from two poles 221 of the switch contact circuit, the switch circuit is disconnected, and the electric signal on the connector terminal 34 of the switch circuit is changed, so that the switch function of starting and stopping the automobile by one key is realized.
Referring to fig. 5, the arrows indicate the path and direction of the waste. In order to satisfy the smooth relative movement between the button 1 and the housing 4, a predetermined gap must be left between the button 1 and the housing 4, through which dust and water may enter during use, affecting the smooth movement of the button 1 and the useful life of the electronic components on the PCBA board 22. Therefore, the scheme designs a special antifouling pollution discharge structure. The elastic part 21 further comprises a covering part 213, an upper skirt edge 214 and a lower skirt edge 216 which are annularly arranged along the edge of the covering part 213, a skirt gap 215 is arranged on the upper skirt edge 214, and the PCBA board 22 is jointly wrapped by the lower skirt edge 216 and the covering part 213; an antifouling opening 42 is arranged on one side of the upper part of the shell 4 corresponding to the skirt notch 215. The car start switch is installed in the car obliquely at a certain angle, and when water or dust enters from the gap between the button 1 and the housing 4, part of the water or dust will reach the upper surface of the cover 213 of the elastic part 21 along the gap between the button 1 and the housing 4 due to gravity.
