PROBLEM TO BE SOLVED: To provide a means of conducting certainly a positive and a negative two electrodes of a fixed contact of a push-button switch by a movable contact. SOLUTION: The movable contact 5 has a movable contact pattern 6 of which opposed face to a fixed contact 11 is rectangular shape, and the fixed contact 11 is formed in a fixed-contact forming region 11a of rectangular shape which envelopes the movable contact pattern 6. Its first fixed contact pattern 12a has U-shape electrodes 14 formed in U-shape arranged alternately with the direction mutually reversed, and a conduction wiring 15 conducting between the extended parts 14a of the neighboring U-shape electrodes 14. The second fixed contact pattern 12b is formed of T-shape electrodes 17 which are formed in T-shape by an opposed part 17a arranged opposed at the open end of the U-shape electrodes 14 and a projection 17b projecting from the opposed part 17a toward the connecting part 14b, and connecting electrode 18 which connect the ends of the opposed parts of the neighboring T-shape electrodes 17 and are arranged between the U-shape electrodes 14 arranged alternately.
