Construction and Fit for BMW 3 E46

The panel has been designed for the specific geometry of the passenger door in the BMW 3 E46, which translates to a precise fit with the factory door panel. The appropriately shaped socket for the switch allows for its stable seating, and the correctly positioned mounting points facilitate installation without the need for modifications. This ensures the consistency of the interior's styling lines and the correct positioning of the button relative to the passenger's hand.

As a component from the Switches, Controls, and Ignition Components group, the panel works with the factory window regulator switch, enabling its trouble-free operation and reducing the risk of play or misalignment during use.
