Window lifter key
With the progress of the automotive industry, many parts of today’s cars have changed from manual to electric. The window switch is one of the most important parts of the passenger’s comfort in the car. Today, no car is produced with a manual or manual window. Due to its widespread use. This option in the car, big companies improve it in different ways every day. So that nowadays the car glass is used as a display. The car window switch can be installed in different parts according to the car model and its overall design. For example, some cars are designed in such a way that there are window lifter keys on all four of their doors. At the same time, modern cars with a special design are offered to the market. These cars are designed in such a way that the driver can access one key and raise and lower all the windows. In addition, in some cars, we also see that the window lifter key for the rear windows is installed between the two front seats.
Signs of failure of the car window switch
When the car’s power window switch fails, it will show symptoms. For example, sometimes one of the keys is not able to raise and lower the glass properly. In addition, if the driver’s automatic key also fails, it may not be possible to raise and lower all the windows. Sometimes the child lock does not work and you see problems in this field.
In the meantime, you should know that there are various reasons that will cause the failure of this functional part. For example, sometimes people hit the power window buttons unintentionally. Then you will see that these parts cannot perform the desired process well. In addition, excessive use of low-quality keys will make you need to replace them in a short period of time. Sometimes the broken keys are also considered as one of the reasons that will cause the failure of this part.
There are various other reasons that cause disruption in the working process of the window lifter keys. However, sometimes the raising and lowering of the car windows may originate from the internal systems of the car. It is better to check other parts first before starting to replace the window switch. If you do not have expertise in this field, you can get help from an experienced person.
Using car window booster
Sometimes boosters can be used to increase the speed of the window lifter. This mechanism is built so that the driver can use an amplifier. Reinforcing the glass by using two relays and using positive and negative wires allows you to make the window lifter motors more powerful. We have come to the conclusion that the use of this solution can be effective to a large extent. However, don’t forget that it is important to use a fuse in this situation.
You may have a question about when you will need to use a booster for the car lift system? When the electric wires of the glass become weak and cannot perform properly due to wear and tear, you can use this mechanism. Spotting the platinums also causes the amplifier to be used.
Sometimes the window lifter key is weak or the type of key you want is not available in the market. For this reason, you can take help from this mechanism. Don’t forget that by using this system, you can avoid buying a high-priced window lifter key.
Functions of the window lifter key in new car options
With the addition of various options to the car, the power window switch has taken on a more colorful role and in the form of a complete electrical system, it has taken control of all parts of the door.
The different parts that the power window switch controls are as follows.
- Control the door glass to move up or down
- The possibility of automatic movement of the windows up or down
- Central door lock control
- Side electric mirror control and mirror heater
- Door lights control
- Electric folding mirror control
- Open the trunk door
- Connection of memory seat buttons
The mentioned items are only the typical tasks that a power window is responsible for and it changes depending on the type of car and the options.
Types of window lifter keys
In terms of operation and design, lifting glass keys are classified into two general types:
- Electronic window switch or power window
- Simple lift glass key
Electronic window switch or power window
The word “power window” is the Latin name of the electronic power window keys and it is different from the power window part that is used in the market to automatically raise the windows when the doors are locked. added at the time of locking the doors. But the manufacturers believe that the automatic raising of the windows can pose a danger to human life, especially children.
This new generation window lifter switch uses a very weak current to command the control unit. The control unit provides the power required by the window lifter motor by means of relays or high current drivers. In some cases, these relays and the electric drivers are located on the lifter window key set itself, and the information is transmitted to other doors using only two thin wires. Multiplex technology is used in some of these types of lifter window keys, and in others, point transmission is used. To the point. But the thing that sets this key apart from simple keys is the use of thinner wires to connect the doors.
Simple car window lifter key
In the past and in simpler cars, a normal window control key was used to move the car windows. The structure of this key is such that it consists of two double-sided platinum mechanisms together and a plastic button to control the car windows. used. In this switch, the platinums are always connected to the two output pins towards the lift window motor. When no force is applied to the lift window button, these two platinums are connected to the other two platinums which are negative, and this causes It is always negative at both ends of the lift glass motor. One of these platinums moves downwards with the movement of the lift glass button, and this time the main plate is connected to the positive plate and one of the legs of the lift glass motor becomes positive. By releasing the button The lifting glass pair of plates become negative again. But the second platinum moves when the lifting glass button is raised and connects to the positive plate. And this time the other base of the lifting glass motor becomes positive. Connecting and disconnecting these plates should be made of metal with low electrical resistance and resistant to corrosion and tarnishing.
