Switch-containing cable

A switch-containing cable for earphones comprising:

• a belt-like first conductor film including a first belt-like base material on an inner surface of which a first conductor is disposed;
• a belt-like second conductor film disposed oppositely to the first conductor film through a gap and including a second belt-like base material on an inner surface of which a second conductor is likewise disposed;
• an insulating spacer arranged between the second conductor film and the first conductor film to maintain a gap therebetween;
• and
• a belt-like sheath having a hollow cavity extending in a length direction to a greater extent than either width or height directions, the belt-like first and second conductor films and the insulating spacer being held in the hollow cavity extending in the length direction, and the belt-like first and second conductor films function as a switch member in the hollow cavity when pressed together in the height direction;
• wherein lead wires for carrying audio signals are provided in lead wire insertion holes formed in widthwise two ends of the sheath extending in the length direction in parallel with the hollow cavity;
• wherein the belt-like first conductor film is not fixed to either the insulating spacer or the belt-like second conductor film in the hollow cavity where the belt-like first and second conductor films function as the switch member;
• and
• wherein the belt-like first conductor film is movably overlaid on the insulating spacer, and the hollow cavity of the sheath includes adequate margins, such that when the sheath is bended in the length direction, relative displacement of at least the belt-like first conductor film over the belt-like second conductor film is allowed within the hollow cavity in the length direction, avoiding inadvertent function of the switch member when the switch-containing cable for earphones is bended.
