发明名称 METAL MESH CONTACT AND SWITCH AND METHOD FOR PROCUDING THE SAME
摘要 An electrical contact (1) according to the present invention comprises a core body (3) made from elastic material and having outer, inner and side surfaces, a metal mesh layer (5) extending the outer and side surfaces of the core body (3) and a bonding layer (7) covering the edge of the metal mesh layer (5) at the side surface of the core body (3). Since the metal mesh layer (5) is provided to the outer surface (contact surface) of the core body (3), the outer surface comes in contact with the other contact surface with a number of contact points. By providing the bonding layer (7), the edge (cut surface) of the metal mesh (5) is rarely exposed to air and the rusting which occurs easily at the edge can be prevented. And, the bonding layer (7) has a function for preventing the key top material from coming into around the outer surface of the electrical contact at the process for attaching the contact (1) to the key top. Accordingly, an electrical contact capable of having a number of contact points such as a metal mesh, preventing rust of the metal mesh and further failure of bonding operation to a key top of a key switch can be provided.
