摘要:
A sheet switch comprises a pair of flexible insulative films, one of which is provided with a plurality of electrodes, resistances connected to the electrodes, respectively, and line patterns for externally connecting the electrodes via the resistances. The other insulative film is also provided with a plurality of second electrodes at positions corresponding to the first electrodes, respectively, and a space is defined between each of the facing electrodes. The line pattern is a laminated structure consisting of an underlayer formed of a low resistance paste and an upper layer formed of a high resistance paste coated over the underlayer. The underlayer formed of a low resistance paste is partially disconnected to define a gap, so that the resistance is formed integrally with the upper layer formed of a high resistance paste at a position corresponding to the gap.
