This product is specifically designed for the BYD Qin PLUS DM-i. It is the core window and door control component integrated into the driver's side door panel—the front window switch (L). This master switch assembly integrates functions including four-door window lifting control, central door locking, window lockout, and power mirror adjustment (including folding). It serves as the "command center" for the driver to control the vehicle's window and door systems, directly impacting convenience and driving safety.

The Qin PLUS comes standard with power windows. The driver's window control switch features two operating positions: Manual (Position 1) for precise window adjustment, and Auto (Position 2) for one-touch operation, allowing the window to fully raise or lower automatically. When the vehicle speed exceeds approximately 20km/h, the central door lock automatically engages for enhanced safety. As a professional automotive electronic parts manufacturer, we develop and produce strictly according to BYD OEM technical standards. Using high-precision injection molding and high-quality micro-switches, the button lifespan exceeds 50,000 cycles, with a scratch-resistant surface and crisp, responsive tactile feedback. The OE numbers precisely match the original vehicle for plug-and-play installation, directly replacing faulty or worn original switch assemblies.
