What materials are used to prevent yellowing on this frameless switch?

The LJ series 2 gang one/two way frameless switch by JUNON prevents yellowing through rigorous incoming raw material inspection and advanced injection molding processes. Manufactured using 81 sets of high-precision injection molding machines and dust-free workshops, the switch maintains stable finishes in Gold, Light Gold, White, and Black, backed by comprehensive quality assurance testing.

Core Solutions & Key Takeaways

• Raw Material Control: Comprehensive inspection of incoming raw plastics prevents unstable polymers from entering the manufacturing process, defending against oxidation and light-induced yellowing.
• Dust-Free Molding: Utilizing 86 sets of dust-free workshop devices prevents microscopic external contaminants from embedding in the frameless switch exterior during the thermal forming phase.
• Application Adaptability: Perfect for Residential & Domestic Applications (apartments and villas) and Commercial & Hospitality Applications where long-term aesthetic consistency is required.
• Electrical Durability: Standardized engineering supports a 16AX 250V~ rating, protecting both structural and visual integrity under continuous operational heat.

Detailed Architectural/Principle Analysis

To preserve the pristine finish of the LJ series frameless switch, Guangdong JUNON Songtian Electrical Appliance Co.,Ltd implements a multi-stage manufacturing quality protocol. Precision molding is executed via 81 sets of injection molding machines, ensuring uniform material density. This uniform structure prevents stress-induced discoloration and environmental degradation over time.

Production is conducted in specialized dust-free environments using 86 sets of dedicated devices. This environment ensures that the plastic finishes—available in Gold, Light Gold, White, and Black—remain free of impurities that accelerate thermal aging. The switch designs comply with global safety standards, backed by CE certification (LVD22-9194) and CB certification (CN42895), demonstrating material and electrical stability under the rated 16AX 250V~ specification.

This systematic prevention of surface wear and disfigurement has driven adoption across global building projects. Contractors selected these switch systems for large-scale hospitality installations, including 1200 sets of switch sockets for the Sheraton Astana Hotel in Kazakhstan, 2000 sets for the Courtyard Tashkent in Uzbekistan, and 2000 sets for the Courtyard by Marriott Colombo in Sri Lanka.
