PURPOSE:To make possible the setting of an operating switch in a band by forming conductive patterns to >=2 sheets of rubber or thermoplastic resin having an insulating characteristic and stretchability and adhering the rubber or thermoplastic resin thereafter. CONSTITUTION:A case 3 consisting of plastic or metal is disposed onto an upper band 1 and an upper switch pattern 2 is formed to the part overlapping flatly on the case 3. A lower switch pattern 6 is formed by kneading and dispersing a conductive material consisting of the same material as the material of the pattern 2 with and into the resin or rubber having the stretchability, then forming the same on the lower band 5 by printing, painting, etc. A lower switch contact 6b is formed in the position facing an upper switch contact 2b. The user presses the upper switch contact part of the upper band 1 by the finder to close the contacts. The contact part returns to the home position by the elasticity of the band 1 and the contacts are opened when the finger is released. The provision of the operating switch in the band is thus made possible. |
