Title:
METAL MESH CONTACT AND SWITCH AND METHOD FOR PROCUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/082420
Kind Code:
A1
Abstract:
Provided is a contact element such as a metal mesh, which can be in contact with an object via a number of contact points, wherein the corrosion of the metal mesh can be prevented, and the trouble which occurs when a key switch is attached to a key top can be prevented.
A contact element (1) is comprised of a core portion (3) composed of an elastic material, which has front, back, and side surfaces; a metal mesh layer (5) which extends on the front and side surfaces of the core portion (3); and a junction layer (7) which covers the end portion of the metal mesh layer (5) on the side surface of the core portion (3). The metal mesh layer (5) is provided on the front surface (contact surface) of the core portion (3), so that the contact element is in contact with the contact surface of an object at a number of contact points. Further, the junction layer (7) prevents the end surface (section) of the metal mesh (5) from being exposed, so that the section can be prevented from being corroded. Further, the junction layer (7) prevents the front surface of the contact element from being in contact with a key top material when the contact element (1) is connected to a key top.
