Automotive Sensing and Control
The micro switch, as a compact yet powerful electronic component, plays an indispensable role. It enables switching functions in circuits, facilitating more sensitive and smooth communication between various systems in vehicles, and its significance is even more pronounced in new energy vehicles. Not only can it perform the functions of traditional vehicles, such as controlling lights and horns, but it also plays a crucial role in the electric drive system, ensuring the safety and reliability of the power system. Firstly, the micro switch plays an important role in the charging system of new energy vehicles. Through precise switch control, the micro switch can ensure the stability and reliability of the charging connection, preventing safety hazards caused by poor connections or abnormal situations. In emergencies, the micro switch can quickly cut off the current, protecting the safety of the battery and charging equipment.

New energy charging and discharging equipment
New energy vehicle charging guns have high power and voltage, while sealed micro miniature switches can operate stably in high voltage, high temperature, and high humidity environments, preventing electrical sparks that could lead to fire or explosion hazards. The small size and lightweight design of the sealed micro miniature switch make the charging gun more portable, providing users with a more comfortable experience. The high reliability and long lifespan of the sealed micro miniature switch also ensure the longevity and stability of the charging gun.

Household appliances and living utensils
Micro switches are compact and highly reliable switches, generally composed of a housing, contacts, a spring, and a lever. Their working principle involves the movement of the lever, which quickly opens or closes the contacts. Due to their design, micro switches can complete switching operations with a small displacement, typically requiring only a few millimeters of travel. They can be used in everyday appliances such as microwave ovens, washing machines, and refrigerators. Unionwell basic micro switches ensure precise functionality and durability even under frequent use. Choosing a reliable basic micro switch can enhance the performance of household devices.

The inductive shaft is a technological innovation that truly addresses user pain points and has practical value. In essence, the inductive shaft has stronger sensing capabilities and higher stability in RT accuracy. It combines adjustable RT accuracy with radar-like active bidirectional sensing technology, which can eliminate various errors. By actively emitting and receiving electromagnetic waves, along with signal processing technology, it achieves precise detection and identification of the shaft's accuracy. Moreover, since this process involves bidirectional testing, the chip can adaptively repair triggered signals based on environmental changes to achieve optimal accuracy. The 255-level adjustable triggering accuracy changes more linearly, providing smoother and more stable triggering.

The advantage of the sealing performance of micro switches lies in its ability to effectively prevent external impurities from entering the switch, ensuring its normal operation. This sealing capability is crucial for protecting the internal circuits from environmental factors such as dust and moisture. Micro switches typically use designs like sealing rings to enhance their sealing performance, ensuring reliability and stability in harsh environments. Additionally, the design of micro switches should also consider reducing unstable and vibration times to avoid contact heating, melting, and potential misoperation of electronic circuits. Therefore, Unionwell micro switches are an excellent choice, as their sealing performance and stability design ensure reliable operation in various working environments.

Automation and Industrial Control
Micro Switch: The "Nerve Endings" of Industrial Control In modern industrial automation systems, micro switches play a crucial role. They are those inconspicuous yet indispensable small components that can precisely control the on and off of electrical currents in various devices. Their working principle is based on the lever principle and spring reset mechanism. When external mechanical force is applied to the switch button, the lever triggers the closing or opening of internal contacts, thereby achieving circuit control. This design is not only simple and reliable but also ensures stable operation of the switch in harsh environments.
