<P>PROBLEM TO BE SOLVED: To provide an inexpensive push switch by lowering a manufacturing cost of a fixed electrode. <P>SOLUTION: A push switch 1 includes an insulation housing 2 having a housing recess 2a on a top face 2b and a bottom face 2c fixed to a mounting board 9, a first fixed electrode 3 and a second fixed electrode 4 disposed in the housing recess 2a at a distance from each other, dome-shaped click springs 6 disposed in the housing recess 2a so as to face the first fixed electrode 3 and the second fixed electrode 4, respectively, and a cover sheet 7 covering an opening of the housing recess 2a and appressed to the top face 2b of the insulation housing 2. The first fixed electrode 3 and the second fixed electrode 4 each made of a flat-plate conductive member having a predetermined outer shape have external terminals 3b, 4b each formed by drawing on the bottom face 2c side of the insulation housing 2 in a convex shape. The external terminals 3b, 4b electrically conducted to lead-out wiring of the mounting board 9 are exposed only on the bottom face 2c of the insulation housing 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
