Document Type and Number:

WIPO Patent Application WO/2007/055157

Kind Code:

A1

Abstract:

A silicone rubber composition having such selective adhesiveness that it shows higher adhesion to an organic material than to a mold is bonded to a sheet of the organic material and is vulcanized and cured in the mold. Thus, an elastomer keypad of a double-layer structure is produced in which an organic material layer (3), which can be easily subjected to coating, bonding with an adhesive or pressure-sensitive adhesive, or the like, has been united and bonded as a surface layer to the rubber. Keytops are bonded to the elastomer keypad to produce a covering member (1) for push-button switches. The organic material preferably is a polyurethane elastomer sheet.
