PROBLEM TO BE SOLVED: To constitute a switch device of a printed circuit board, without the use of a fixed contact piece of an additional member by forming a fixed contact part connected electrically to a specified conductor pattern at the edge part of one end of the printed circuit board. SOLUTION: When through-hole plating is conducted to a printed circuit board 1, a plating film 1e electrically connected to a specified conductor pattern 1b is formed at an edge part 1a for a fixed contact, and when over-plating or soldering of the printed circuit board 1 is conducted, a solder layer is formed on the plating film 1e of the edge part 1a for the fixed contact, and a moving contact is brought into contact with the fixed contact 8 with the solder layer.
