Two Way Key Switch

The Two Way Key Switch is a high-performance industrial component designed for secure circuit management. Engineered by Yijia Industrial Electrical Co., Ltd., this switch utilizes a key-operated mechanism to provide an added layer of operational safety. Each Two Way Key Switch is constructed using premium PBT/PA66 engineering plastics and silver alloy contacts, ensuring a stable 5A current capacity and high electrical conductivity. With integrated high-brightness LED indicators, the switch provides clear visual feedback, making it a reliable choice for consoles, control cabinets, and power distribution systems worldwide.

Technical Specifications

Core Features and Functional Value

Enhanced Electrical Performance

The silver alloy contacts reduce contact resistance to ≤50mΩ, preventing overheating during continuous operation. The brass pins undergo a specialized electroplating process to resist oxidation, ensuring long-term reliability in various environments.

Secure Key Operation

The two-position selector design ensures that only authorized personnel with the physical key can change the state of the circuit, which is vital for safety-critical machinery.

Durability and Maintenance

Utilizing high-accuracy injection molds, Yijia ensures that every Two Way Key Switch meets strict tolerance standards. The robust engineering plastic shell is resistant to impact and wear, reducing the need for frequent replacements.
