A Durable and Vibration-Resistant Micro Switch for Automotive Applications

In the realm of precision control and safety systems, the micro switch plays a fundamental role. Characterized by a small physical size and a quick, snap-action mechanism, this type of switch is designed to operate with minimal physical force and provide highly reliable electrical contact. The core function of a micro switch is to detect the presence or position of an object, or to act as a safety interlock, making it indispensable in applications ranging from industrial equipment to consumer appliances and, critically, the automotive industry.

 

The HK-25-T-009 model is engineered to meet the stringent demands of automotive environments, where vibration resistance and operational stability are non-negotiable. This specific micro switch is built with features that ensure consistent performance despite constant shaking and temperature fluctuations common in vehicles. Its robust construction is validated by a mechanical life expectancy of approximately one million cycles, a testament to its durability and long-term reliability in demanding use cases.

 

Key operational parameters define the performance of this micro switch. It requires an operating force of 5.0 Newtons maximum to activate, providing a deliberate and secure actuation that helps prevent accidental triggering. The total travel distance is precisely set at 16.8±0.3mm, ensuring consistent engagement and disengagement. This micro switch is available in both 2-pin and 3-pin configurations, offering flexibility for different circuit designs, including normally open and common changeover functions.

 

The electrical ratings of this component further highlight its versatility. It is rated for 1A/3A general purpose and 1/4 horsepower at 24VDC, making it suitable for controlling a variety of loads in low-voltage DC circuits. These specifications make this micro switch an ideal component for applications such as brake pedals, door interlocks, or sensor triggers within a vehicle’s electronic and safety systems, where precise and fail-safe switching is critical.

 

The HK-25-T-009 exemplifies the advanced engineering required for modern automotive components. As a specialized micro switch, it successfully combines high mechanical longevity with precise electrical performance and resilience against environmental challenges. Its design and specifications make it a dependable choice for engineers seeking a reliable switching solution to enhance the safety and functionality of automotive control systems.
