3. Flexible Configuration: Available in 2-speed or 3-speed models, supporting 3-pin or 6-pin wiring to adapt to different circuit designs and installation requirements.
4. Clear Operational Feedback: Smooth rotation, clear speed settings, and precise operation.
5. High Versatility: Standard panel mounting dimensions facilitate installation and refurbishment, compatible with conventional equipment housings.
6. Reliable Electrical Performance: Rated 250V AC/5A, high conductivity, and low resistance ensure stable operation of various control circuits.
1. Customer: A leading domestic provider of new energy vehicle charging infrastructure.
2. Challenges: The need to equip public DC fast charging stations with safe and reliable control switches to enable mains power control, prevent unauthorized use and damage, and withstand high-frequency use and outdoor temperature variations; previously used switches were prone to wear, loose contacts, and insufficient safety, leading to service interruptions.
3. Solution: Yaming recommends the LA16-3Y (3-position 6-pin) model. Its key lock structure securely controls power activation, allowing only authorized personnel to operate it. Robust brass contacts and a flame-retardant housing ensure stable conductivity under temperature fluctuations and high-frequency use.
4. Results: After deploying over 5,000 LA16 switches nationwide within 18 months, customer feedback indicates a 92% reduction in control switch-related malfunctions and maintenance needs. Vandalism and unauthorized use have also significantly decreased. This series has been designated as the exclusive control switch for new charging piles.

Q1: Is the LA16 series switch suitable for outdoor or harsh industrial environments?
The LA16 series uses robust, flame-retardant materials and boasts excellent durability. However, its standard protection rating is suitable for indoor industrial control cabinets, panels, and dry environments. For extreme outdoor, high-dust, or high-humidity scenarios, Yaming offers customized sealed models with upgraded IP ratings. For specific environment requirements, please contact our technical team.
Q2: Does the LA16 Series Key Lock Rotary Switch come with spare keys?
Yes. Each LA16 switch comes standard with two dedicated keys. Bulk orders or spare keys can be requested through Yaming's safety key coding management system, requiring the unique key code corresponding to the switch (the code is unique, ensuring security).
Q3: What is the mechanical and electrical lifespan of the LA16 switch?
The LA16 series is designed for long-term use, with a mechanical life of no less than 50,000 operations and an electrical life of no less than 30,000 operations (rated load 250V AC/5A) under standard operating conditions. High-quality brass contacts and precision mechanical components significantly reduce long-term replacement and maintenance costs.
