PROBLEM TO BE SOLVED: To provide a push-on switch which is used for an operation part of an electronic equipment and in which characteristics are stable by suppressing deformation due to heat in soldering. SOLUTION: The center contact part 12A of the center fixing contact point 12 is exposed on the bottom face center of a recess part 11A of a switch base 11, and by embedding, installing, and fixing a first extended part 12B extended and installed in both directions of left upper direction and right lower direction from the center contact part 12A, and by respectively arranging and installing outer fixed contact points 13 at the recess part 11A outer edge parts at the other diagonal position so as to become linear-symmetrical against the diagonal line along that direction, respective insert members are arranged and installed at switch bases so that there is no deviation, thereby deformation of the switch bases can be suppressed in soldering and the push-on switch of stable characteristics can be provided.
