Product Advantages

This heavy-duty SPST rocker toggle switch is engineered for high-current industrial and commercial applications. Adopting bakelite and PA66 composite housing, it features outstanding high temperature resistance and flame retardancy, which can withstand harsh working environments. The silver-plated metal bat handle is anti-oxidation and wear-resistant, ensuring stable operation after long-term use. With two universal AC ratings (15A 250V & 20A 125V), it covers most mainstream low and medium voltage circuits worldwide. The ultra-low contact resistance ensures stable power transmission, and 500VDC insulation performance fully guarantees electrical safety. The product complies with EU RoHS environmental regulations, restricting harmful substances, so it can be freely exported to EU, North America, Southeast Asia and other regions. Featuring long mechanical and electrical lifespan, simple mechanical structure and low maintenance cost, it is a cost-effective universal switching component for global equipment manufacturers and distributors.
