silver ink innovation

The potentiometer risistor combined by electrode and resistance. normally, the electrode of film carbon pot has two type material, silver ink and other metal. To get higher cost performance, many pot manufacturer use silver ink as electrode. But ordinary silver ink as the electrode which wear-resisting is not enough, and it determines the life of product.  Some manufacturer use one special ink to improve the product service life, but the ways will increase product cost and influence product contact performance. To match some customer long life and lower residual resistance requirements, EVERSON guys get one type silver ink, which can passed 2 million wear-resisting test, through technical research, and the feeling of prodcuts of rotating and sliding handle is better.
