This Door Contact Switch, part number 6366C0, is specifically designed for PEUGEOT and CITROEN vehicles. It plays a crucial role in your car's electrical system, primarily by signaling to the vehicle's computer whether a door is open or closed. When a door is opened, this switch activates, triggering the interior lights to illuminate and informing the car's security system. Conversely, when the door is closed, the switch deactivates, turning off the lights and arming the alarm system if engaged. A malfunctioning door contact switch can lead to interior lights not working, false alarms, or the car not recognizing when a door is ajar. Crafted to meet the original equipment manufacturer's specifications, this switch offers a perfect fit and reliable performance. Replacing a faulty switch with this part ensures the proper functioning of your vehicle's convenience and security features, restoring them to their intended operation.
