Description

Technical Field

[0001] The invention relates to the technical field related to automobile switches, and in particular to a combination switch with a mounting bracket. Background Art

[0002] The automobile combination switch is a switch that is often used as a power source in the electrical control circuit. It can be used to directly start or stop a small power motor or reverse the motor. It is installed on the steering column of the car and consists of two or more switches used to control the car's lights, signals, and control electrical appliances. It is a multifunctional switch that integrates a wiper switch (high speed, low speed, intermittent, and off), a steering switch (left and right steering and lane changing), a dimmer switch (high beam, low beam, and overtaking), a washing button switch, and a horn button switch. It is usually a handle type and is installed on the steering column under the steering wheel for the driver to operate.

[0003] At present, many car owners leave their cars for a long time after parking, and the cars are easily stolen and driven away. For this reason, most car owners choose to install anti-theft alarm devices on their cars. At present, when the car anti-theft alarm devices receive illegal trigger signals detected by their external sensor accessories, the alarm devices sound an alarm to deter theft activities and connect the power supply connected to the engine to the ground through an analog switch to lock the engine, so that the vehicle engine cannot be started. Such technologies and accessory technologies have been clearly disclosed in society, and the safety factor is not high; in addition, when the anti-theft device is turned on during normal parking, when the vehicle is triggered by thunder, heavy rain or strong wind vibration, the vehicle will sound an alarm, which not only gives the owner wrong vehicle information, but also disturbs nearby residents with the alarm sound. When the anti-theft alarm device is not turned on, the safety of the vehicle is even less guaranteed, and the vehicle will be stolen unknowingly. Summary of the invention
