Application of Unionwell G307 in Automotive Electronic Parking Brake (EPB) Systems — Featuring Dual Circuit Loop Momentary Micro Switches

With continuous advancements in automotive electronics, the Electronic Parking Brake (EPB) system has become a vital safety feature in modern vehicles. As a key component of EPB systems, micro switches play a critical role in precise detection and signal transmission. Unionwell's G307 series, with its outstanding performance, is an indispensable choice for automotive electronic parking brake systems, especially thanks to its dual circuit loop momentary micro switches design, which significantly enhances system safety and reliability.

What Are Dual Circuit Loop Momentary Micro Switches?

Dual circuit loop momentary micro switches refer to micro switches with a dual-circuit design that operates in a momentary (instantaneous) manner. This design enables two independent circuits to be triggered simultaneously, greatly reducing the risk of single-point failure and ensuring accurate signal transmission and stable system operation. In automotive EPB systems, these switches quickly respond to the handbrake mechanism’s position status, ensuring vehicle parking safety.

Advantages of Unionwell G307

• Dual Circuit Synchronous Response

  The G307 features a high-quality dual circuit design that guarantees synchronous output of two circuits, improving redundancy and safety of the EPB system.

• High Momentary Action Sensitivity

  Its momentary micro switch characteristics ensure response times under 15 milliseconds, preventing potential safety hazards caused by delays.

• IP67 Dust and Water Resistance

  The series offers excellent sealing performance to withstand harsh automotive environments and ensure long-term stable operation.

• Compatible with Multiple Mounting Methods

  Supports both DIP and SMT mounting styles, catering to different automotive manufacturing processes and easy integration into various EPB modules.

Specific Application of G307 in Automotive EPB Systems

In electronic parking brake systems, the G307 micro switch accurately detects whether the handbrake is fully engaged or released. When the driver operates the handbrake, the G307 dual circuit momentary switch instantly sends position change signals to the control module, which then determines if the parking command has been successfully executed—thus preventing vehicle rollaway caused by incomplete brake engagement.

Moreover, the G307's high durability ensures consistent performance under frequent use, meeting the automotive industry's strict requirements for component lifespan and reliability.

As a brand specializing in micro switches, Unionwell's G307 series of dual circuit loop momentary micro switches provides reliable technical support for automotive electronic parking brake systems. Choosing Unionwell means choosing high quality and trusted safety.
