What does the switch assembly of the car mean？
The switch assembly of the car refers to the main switch used to control various electronic equipment, lights, horns, air conditioning and other facilities on the car. It is an important part of the automobile electrical control system, which controls the functions of the automobile in the form of switches. It usually includes a main switch and some secondary switches, the main switch can control the switching state of the vehicle power supply, and the secondary switch can control some specific functions of the switch, such as fog lights, reversing radar, etc.
The switch assembly of the car has many important functions and roles. It can control the power switch state of the car, such as starting or stopping the engine, closing or opening the doors, Windows and other devices. At the same time, it can control the switching state of various lights, such as headlights, rear taillights, fog lights, etc. In addition, the switch assembly can also control the power switch status of seat heating, air conditioning, audio and other facilities. In short, the switch assembly can make the car more convenient, comfortable and safe.
There are some issues to be aware of when using the switch assembly. First of all, ensure that the switch assembly is operated correctly and do not misoperate the switch assembly. Secondly, it is necessary to avoid keeping the switch assembly in a state of extension without actual use, so as not to cause damage to equipment such as batteries. Finally, it is necessary to avoid frequently opening or closing the switch assembly in the vehicle, so as not to cause damage to the vehicle circuit and other facilities. Only by strictly complying with the use specifications of the switch assembly can it play its maximum role.
The combination of automotive switches mainly controls the lighting system, the light signal system, the wiper and window scrubber system, and the hazard alarm flash system.
The car combination switch is an integrated device inside the car, which combines a variety of functions in one to provide a convenient operating experience for the driver. Its main functions include:
Lighting and light signal control : Control the turn signal lamp, headlamp and other lights through the left handle, including the control of the turn signal (clockwise for right turn, counterclockwise for left turn). In addition, it also includes the control of instrument lights, front lights, rear lights, license plate lights, as well as the opening of headlights and the use of high beams.
wiper and window scrubber system control : The right handle controls the wiper and window scrubber, providing different working modes, such as intermittent, low speed and high speed, and can be pulled up by the handle to spray the window washing liquid.
Danger alarm flash control : danger alarm flash button in the middle above the combination switch, press down to turn on the danger alarm flash, which is used to alert other vehicles.
The combination switch is designed with the operating experience and safety in mind, and its different operating characteristics, including gear selection, transition force and reaction speed, are carefully calibrated to ensure that the driver can operate easily and accurately. In addition, its anti-interference ability can not be underestimated, such as in rainy days can easily open the wiper, reduce interference, maintain a clear line of sight. For drivers who often drive at night, it is particularly important to keep the vehicle combination switch in good condition, so regular inspection and maintenance is essential, so as to ensure that the switch is always in the best working condition for driving safety .
The reasons for the failure of the automotive switch assembly may include the following:
internal fault : the internal moving and static contacts of the combined switch are not in good contact, or the rated current of the switch is less than the current of the load loop, resulting in arc erosion of the internal contacts of the switch. This may require adjusting the moving or static contacts or switching to a switch with a higher rated current .
torsion spring problem : the torsion spring on the rotating shaft inside the combination switch is soft or broken, causing the moving contact to fail to rotate, resulting in the change of the position of the contact. This needs to be replaced with a new torsion spring of the same specification .
loose fixing bolt : The fixing bolt of the combination switch is loose and the rotating operation is frequent, and the conductor pressure contact is loose, resulting in discharge, ablation or break of the external connection point. The fixing bolts should be tightened in time, and the number of operations can be reduced.
line problems : including wire unsolder, wire drop or wire insert slip, these problems may lead to light failure or light flicker .
relay problem : relay contact is poor or damaged, which may cause headlight operation problems or other related function failure .
CAN communication exception : the combination switch may fail. You need to perform corresponding maintenance .
external factors : such as environmental factors, improper use or aging, etc., may also cause the combination switch failure .
Solving these problems usually requires professional technology and tools, if you encounter related faults, it is recommended to contact a professional car repair service for inspection and repair.
