Liyond Micro Switch Manufacturer China

Liyond's Micro Switches, often referred to as miniature snap-action switches, are essential and highly reliable components in high-voltage and medium-voltage electrical systems. These precision devices convert a mechanical movement—such as the operation of a circuit breaker or MV disconnector—into an accurate electrical signal for control and indication purposes.

Precision Control and Safety Interlocking

As a professional micro switch manufacturer, our micro switches are indispensable for safety and sequencing operations within medium voltage switchgear, ensuring the correct status and control of electrical circuits.

Key Applications:

• Position Indication: Provides accurate remote electrical feedback on the position of the main vacuum circuit breaker, isolating switch, or disconnector (e.g., fully Open or fully Closed).

• Safety Interlocks: Crucial for interlocking systems to prevent misoperations. They ensure that sequential operations (like charging a spring mechanism or closing a circuit) only occur when the mechanical movement has reached the required limit.

• Control Circuit Logic: Used in control systems to activate or disable auxiliary functions and sequence the operational steps of high-voltage equipment.

Technical Features

Liyond designs its micro switches for demanding industrial and utility environments, focusing on durability, responsiveness, and versatility.

• Reliable Snap-Action Mechanism: Ensures a quick-break operation, which provides a clean switching action, minimizing arcing and maximizing both mechanical and electrical life.

• High Durability: Engineered for long mechanical and electrical life, capable of handling the frequent operations required in critical distribution systems.

• Versatile Actuators: Available with various actuator types—including roller, plunger, and lever—to fit specific mechanical interfaces within different switchgear assemblies.

• High Protection Ratings: Select models feature high ingress protection (e.g., IP67) for reliable performance in harsh environments where dust, moisture, or damp conditions are present.

• High Electrical Rating: Capable of handling the necessary voltage and current capacities for use in medium and high-voltage auxiliary control circuits.
