  • the polymer fibers have the advantage that they are flexible and durable and do not corrode when washed or in contact with perspiration and other liquids.
  • a knit of different yarns in a zig-zag pattern is produced and heated.
  • the yarns have different coefficients of expansion. Accordingly, the yarns align during the heating process and the two knitted surfaces of the button remain as in FIG. 4 shown spaced from each other.
  • the elasticity and flexibility of the knit allow the button to be incorporated directly into the knit in a knitting process.
  • the button is so elastic that it can be slightly compressed by hand on the one hand and on the other hand, the surfaces are moved apart when releasing the pressure again.
  • the polymer material gives a good feel, which makes the contacting noticeable to the user.
  • the thread of one of the surfaces 62 and 64 is connected to the neutral.
  • the yarn of the opposite surface is set to a higher potential.
  • the edge of the surface connected to the neutral is slightly larger than the edge of the higher potential surface. This area is surrounded by a non-conductive thread, such as wool.
