Method of production of series of a tactile contact units and tactile contact unit, and series of tactile contact units and a tactile contact unit produced by using the same method

A series of tactile contact units comprising:

• a flexible insulating pad having a side, a through-hole and a plurality of reference holes spaced at first intervals at the side;
• a tactile contact disposed in the through-hole;
• and
• adhesive patterns printed, adhered, and spaced at second predetermined intervals, based on the reference holes, on an upper side of said flexible insulating pad,
• wherein the through-hole is disposed at a position, based on the reference holes, excluding positions at which said adhesive patterns are printed and adhered on said flexible insulating pad.

A method of producing a tactile contact unit with a tactile contact disposed in a through-hole formed in a flexible insulating pad, said method comprising:

• providing a plurality of reference holes spaced at a first interval at a side of the flexible insulating pad;
• printing and adhering adhesive patterns spaced at a second interval, based on the reference holes, on an upper surface of the flexible insulating pad;
• providing the through-hole at a position, based on the reference holes, excluding a position at which the adhesive is printed and adhered on the flexible insulating pad;
• disposing the tactile contact in the through-hole;
• and
• separating the flexible insulating pad by cutting out a predetermined outlined shape.
