Abstract

PURPOSE: To reduce a size of a switch matrix by winding a wire covered by a material insoluble to a specific solvent around the surface of a core material soluble to the specific solvent and further dissolving and removing the core material by utilizing the specific solvent after establishing a molding by the insoluble material.
CONSTITUTION: In utilizing a tetrahydrofuran for the solvent, a core material 1 made of a polyvinyl chloride is into a hollow state to be easily dissolved, and the thickness thereof is made as thin as possible. Subsequently, a wire 2 covered to be insulated by a polyvinyl butyral and others difficult to be dissolved by the solvent is wound around the core material 1 to form a coil 3, and a molding is achieved by utilizing "ARALDITE" 4 difficult to be dissolved by the solvent. Thereafter, the core material 1 is dissolved to be removed by the tetrahydrofuran and to produce a bobbinless coil 5. According to such a process, it is possible to form the switch matrix having a lead switch arranged in a lattice state in a small size.
