PURPOSE: To accurately and securely fix a switching part to a printed board by press-fitting a protruding locking leg part into an attachment hole of the printed board, and press-fixing the switching part to the printed board with elasticity.
CONSTITUTION: By means of inserting a locking leg part 71D of a holder 71 to which a switching element 11 is fixed into a holder attachment hole 12B on a printed board 12 and inserting a lead terminal 11A of each switching element 11 into a through-hole 12A. the holder 71 can be fixed to the printed board 12 with the bifurcate elesticity of the locking leg part 71D. Under this situation, the bottom face of a wall part 71A of the holder 71 is brought into contact with the printed board 12 so as to be positioned, and the holder 71 is balanced toward the board 12 due to the tapered shape of the locking leg part 71D and the elesticity of each bifurcate-formed part. Thus, an operation stroke between a switching part 70 and a operation part 40 can be set accurately.
