[0016] In one embodiment, see Figure 1-Figure 3A central control switch with a high waterproof grade includes a base 12, the base 12 is clamped with a housing 6, a PCBA 11 is arranged on the upper surface of the base 12, the surface of the PCBA 11 is covered with a conductive rubber 10, a knob button seat 9 is arranged in the middle of the PCBA 11 and connected to the middle of the housing 6, a plated knob 3 is arranged on the knob button seat 9, a danger light button seat 5 is arranged on the left side of the housing 6, a danger light button 2 is arranged on the danger light button seat 5, a central control lock button 15 seat is arranged on the right side of the housing 6, and a central control lock button 15 is arranged on the central control lock button seat 17. The danger light button 2 and the central control lock button 15 are spray-painted according to the appearance requirements; the surface is provided with a translucent symbol of the function name, and is assembled with the danger light button seat 5 and the central control lock button 15 seat to move as a whole. The danger light button seat 5 and the central control lock button 15 seat cooperate with the rib groove of the housing 6 to drive the danger light button 2 and the central control lock button 15 to move up and down, pressing the conductive rubber 10. The shell 6 is provided with ribs inside so that the hazard light button 2 and the central lock button 15 can slide smoothly up and down inside as a whole. The knob button seat 9 is connected to the encoder on the PCBA 11 to control the multimedia volume of the vehicle. The PCBA 11 is provided with conductive disks, LED light-emitting elements and other electrical components that correspond to the conductive rubber 10. The LED light-emitting elements provide working status indication and key function symbol backlight for the switch. A pin assembly is welded on the PCBA 11 to facilitate communication with external mechanisms and realize functional output.
