F01-3720030FL
Product Details
1. Basic Overview & Core Functional Positioning
The F01-3720030FL Electronic Parking Switch is a genuine Original Equipment Manufacturer (OEM) component exclusively developed and produced by Chery Automobile Group, specifically tailored for the Chery Jetour X70 mid-size SUV—a model renowned for its user-friendly design, advanced configuration, and reliable performance in urban and long-distance driving scenarios. As a critical core component of the vehicle’s electronic parking system (EPB, Electronic Parking Brake), this electronic parking switch (hereinafter referred to as "the switch") is mounted on the Jetour X70’s central console, within easy reach of the driver, serving as the human-machine interaction terminal that controls the activation and deactivation of the electronic parking brake. It replaces the traditional mechanical handbrake lever with a compact, ergonomic button design, integrating seamlessly with the vehicle’s interior layout while delivering precise, convenient parking control—directly affecting the vehicle’s parking safety and driving convenience.
Unlike traditional mechanical handbrakes that rely on manual force to pull a lever and tension a steel cable, the F01-3720030FL Electronic Parking Switch operates through an electronic signal transmission mechanism. When the driver presses the switch, it sends a precise electrical signal to the vehicle’s Electronic Control Unit (ECU), which then controls the EPB actuator to clamp the rear brake calipers, locking the rear wheels and achieving stable parking. When the driver presses the switch again (or when the vehicle meets automatic release conditions, such as engaging the drive gear and stepping on the accelerator), the switch sends a release signal to the ECU, which controls the actuator to release the brake calipers, allowing the vehicle to move freely. Additionally, the switch is integrated with the vehicle’s safety system, featuring a built-in feedback mechanism that sends a signal to the instrument panel to illuminate the parking indicator light, reminding the driver of the current parking status. It also works in tandem with the vehicle’s anti-lock braking system (ABS) and electronic stability program (ESP) to prevent wheel lock-up during emergency parking, ensuring parking safety on slopes or slippery roads.
The part number F01-3720030FL serves as a unique identifier for this electronic parking switch, distinguishing it from other control switches in the Jetour X70’s central console (such as air conditioning switches, audio switches, or driving mode switches) and electronic parking switches used in other Chery or Jetour models (such as the Jetour X90, Chery Tiggo 7, or Chery Arrizo 8). These models are equipped with different EPB system configurations, switch interfaces, and signal protocols, making their electronic parking switches non-interchangeable. As a genuine OEM component, the F01-3720030FL strictly complies with Chery’s original design standards, material requirements, and performance specifications, while also adhering to international automotive quality and safety standards (ISO 9001, IATF 16949) and national automotive electronic component standards (GB/T 21437-2018). Every dimension, interface pin, and signal transmission parameter is precision-engineered to perfectly match the Jetour X70’s EPB system and central console layout, ensuring seamless integration and stable signal transmission. Unlike low-quality aftermarket electronic parking switches that often suffer from signal interference, contact failure, or incorrect feedback, the genuine F01-3720030FL undergoes rigorous testing and validation to ensure reliability, responsiveness, and long service life, making it the preferred choice for Jetour X70 owners and professional automotive repair technicians.
2. Premium Material Selection & Precision Manufacturing Process
The Chery Jetour X70 F01-3720030FL Electronic Parking Switch is crafted from high-performance, automotive-grade materials, carefully selected by Chery’s engineering team to withstand the harsh operating conditions of the vehicle’s interior—including exposure to varying temperatures (ranging from -30°C to 80°C), humidity, frequent pressing operations, and potential scratches or impacts. The team prioritizes materials that balance durability, ergonomics, electrical conductivity, and corrosion resistance, ensuring the switch maintains stable performance over a service life of typically 100,000–150,000 pressing cycles under normal operating conditions (depending on usage frequency and maintenance habits).
The outer shell of the F01-3720030FL Electronic Parking Switch is made of high-strength PC/ABS engineering plastic, a premium automotive-grade material widely used in interior control components due to its excellent mechanical properties and aesthetic appeal. This composite material offers superior impact resistance and toughness, ensuring the switch can withstand accidental impacts or drops without cracking or deformation. It also exhibits excellent heat resistance and dimensional stability, maintaining its shape and performance even in high-temperature environments (such as direct sunlight exposure) or low-temperature conditions. Additionally, the PC/ABS shell is treated with a matte anti-scratch coating, which not only enhances the switch’s tactile feel but also prevents scratches and fingerprints, keeping the switch looking new for a long time. The coating also has good wear resistance, ensuring the switch’s surface does not fade or peel even after frequent use.
The internal core components of the switch, including the contact terminals, spring, and signal transmission module, are made of high-quality materials to ensure reliable electrical performance. The contact terminals are made of oxygen-free copper (OFC) with a gold-plated surface, which offers excellent electrical conductivity, low contact resistance (≤50mΩ), and strong corrosion resistance. The gold plating prevents oxidation and rust, ensuring stable signal transmission even after long-term use. The spring is made of high-strength stainless steel (304), which provides consistent elastic force, ensuring the switch’s pressing feel is smooth and responsive, without jamming or loose feedback. The signal transmission module is encapsulated in a waterproof, dustproof resin material, which protects the internal circuit board from moisture, dust, and electromagnetic interference—critical for maintaining stable signal transmission in the vehicle’s complex electronic environment. Consistent with advanced electronic component design, the switch also incorporates a flange structure at the mounting interface, which enhances installation stability and prevents loosening during vehicle vibration.
The manufacturing process of the F01-3720030FL Electronic Parking Switch follows a strict, ISO 9001 and IATF 16949 certified production workflow, consistent with Chery’s global quality standards and advanced precision manufacturing practices. The production process begins with the injection molding of the PC/ABS outer shell, using high-precision injection molding machines to ensure uniform material density and precise dimensional accuracy, eliminating defects such as burrs or uneven surfaces. After molding, the shell undergoes a series of post-processing steps, including deburring, surface polishing, and anti-scratch coating treatment, which enhance the shell’s appearance and durability. The internal contact terminals are precision-stamped and gold-plated using advanced electroplating technology, ensuring consistent plating thickness and uniform conductivity.
The signal transmission module is assembled using SMT (Surface Mount Technology) to mount electronic components (such as resistors, capacitors, and chips) on the circuit board, ensuring high assembly precision and stable electrical performance. The entire switch assembly undergoes rigorous quality control testing, including electrical performance testing (signal transmission accuracy, contact resistance), mechanical performance testing (pressing force, service life), environmental testing (high and low temperature resistance, humidity resistance, dust resistance), and electromagnetic compatibility (EMC) testing. The service life testing ensures the switch can withstand over 150,000 pressing cycles without contact failure or signal loss, meeting Chery’s strict durability requirements and ISO 16750 electronic component standards. Additionally, the switch is tested for waterproof and dustproof performance, achieving an IP65 protection rating, which prevents moisture and dust from entering the internal components and causing malfunctions. Only electronic parking switches that pass all these tests are allowed to leave the factory, ensuring the F01-3720030FL series delivers reliable, long-lasting performance in the Jetour X70’s EPB system.
