Sheet-like switch with nonoverlapping conductive patterns |
摘要 |
A sheet-like switch is disclosed in which the migration of silver can be prevented without requiring the provision of an overcoat. An upper electrode sheet is formed by disposing upper contacts and upper conductive patterns electrically connected to each other on an insulating sheet. A lower electrode sheet is formed by disposing lower contacts and lower conductive patterns electrically connected to each other on an insulating sheet. The upper and lower electrode sheets are stacked on each other across a spacer film provided with a hole. The upper and lower contacts are placed to opposedly face each other within the hole, and the upper and lower conductive patterns located within the hole are extended to the exterior in different directions, so that the upper and lower conductive patterns positioned on the peripheral portion of the hole can be prevented from overlapping each other across the spacer film in the upward and downward direction. Further, the length along the peripheral portion of the hole defined between the upper and lower conductive patterns positioned on the peripheral portion may preferably be 0.5 mm or greater.
