DOOR CONTROL MODULE (DCM)

DOOR CONTROL MODULE (DCM)
Beschreibung
The door control module is located on the main driver's side, making it easy for the driver to centrally control the windows throughout the vehicle. There are several function buttons on the switch, the most prominent of which are the window one-touch up/down button and the window lock button. The one-touch up/down function allows the driver to quickly and fully open or close the windows, while the window locking function is used to lock the power controls of the other windows, ensuring that passengers cannot operate the windows themselves.
How the button functions are implemented
1. One-touch window up/down function
When the driver presses or releases the one-touch raise/lower button, the top lever inside the button is pressed or reset accordingly. During this process, the lever pushes the conductive rubber to contact or separate from the gold plated disk on the PCB (Printed Circuit Board). Changes in the contact state between the conductive rubber and the gold-plated disk will change the current state in the circuit, thus triggering the operation of the window motor and realizing the raising and lowering of the window.
2. Window lock function
When the driver presses the window lock button, the mechanism inside the button will push the conductive rubber to contact the gold-plated disk on the PCB. Similar to the one-touch up/down function, this change in contact state will change the current state in the circuit, thus triggering the operation of the window locking mechanism.
