Recently we found some switches in the market carrying our brand, but not made by us. We duly reported the case to UL, who has openned a case no., published in UL website and begin investigating it, UL case number: 2009FR-902. Using counterfeit switches may cause some unexpected damage and loss as they do not pass strict life testing or use bad quality material. If you have any doubt about this, please contact us as soon as possible.
