Problems solved by technology

[0002] The light switch (headlight switch, front and rear fog light switch, etc.) is a switch with a high usage rate on the car, and the failure rate and replacement frequency of the switch are relatively high. At present, the more common installation methods are plastic or metal buckles directly fixed and installed in the holes of the interior panels. This kind of switch is easy to assemble, but it is difficult to disassemble, and it is easy to scratch the interior surface.
Others are installed on the steering column bracket under the steering wheel. Because this switch is integrated with the steering switch, the process of assembling and replacing this switch will be more cumbersome. Some need to disassemble the steering wheel and airbag.

Abstract

The invention discloses a rotating light switch. The switch comprises a pedestal, an inner rotary cylinder and a rotary knob body. The inner rotary cylinder and the pedestal are rotatably cooperated. The pedestal is provided with a pin. The pedestal is also provided with at least one positioning structure. The positioning structure comprises a spring, a positioning pin and a vertical plate. An outer end of the positioning pin is located outside the pedestal. In one positioning structure, a spring outer end is fixed with an inner end of the positioning pin, a spring inner end is contacted with the pedestal; a main top spring is arranged in the pedestal, an upper end of the main top spring is contacted with a bottom of the inner rotary cylinder; and the bottom of the inner rotary cylinder is provided with a push head body used for pushing the vertical plate. The push head body and the positioning structure form one-to-one correspondence. In the corresponding push head body and the positioning structure, a spacing between a push head body bottom and a pedestal bottom is greater than a spacing between a vertical plate top and the pedestal bottom. The push head body is located between an outer end of the positioning pin and the vertical plate. The switch of the invention has advantages that the structure is reasonable; operation is simple; assembling and dismounting can be performed rapidly; installation is simple; and during dismounting, inner ornaments are not damaged, which is good for maintenance and replacing.
