A push switch (1, 2, 3, 5) comprising: a substrate; a first fixed contact point disposed on a surface of the substrate; a second fixed contact point disposed around the first fixed contact point on the surface of the substrate; and a convex dome-shaped movable member disposed on the surface of the substrate so that an end part of the movable member is in contact with the second fixed contact point, the movable member being pressed so as to invert the dome shape and thereby establish conduction between the first fixed contact point and the second fixed contact point; characterized by a buffer member (30, 32, 34) disposed between the movable member and the substrate so as to cover the first fixed contact point without being in contact with the second fixed contact point when the buffer member (30, 32, 34) is not pressed through the movable member, the buffer member (30, 32, 34) adjusting an operation load applied to the movable member during inversion of the dome shape, wherein the buffer member is a leaf spring interposed between the substrate and the movable member to cover the first fixed contact point, or wherein the buffer member is conductive rubber mounted on the substrate to cover the first fixed contact point, or wherein the substrate includes one of a through hole and an indentation in a portion with which the movable member comes into contact upon the inversion of the dome shape, the first fixed contact point is disposed around the one of the through hole and the indentation, and the buffer member is a leaf spring mounted on the substrate to cover the first fixed contact point and the one of the through hole and the indentation. a substrate; a first fixed contact point disposed on a surface of the substrate; a second fixed contact point disposed around the first fixed contact point on the surface of the substrate; and a convex dome-shaped movable member disposed on the surface of the substrate so that an end part of the movable member is in contact with the second fixed contact point, the movable member being pressed so as to invert the dome shape and thereby establish conduction between the first fixed contact point and the second fixed contact point; characterized by a buffer member (30, 32, 34) disposed between the movable member and the substrate so as to cover the first fixed contact point without being in contact with the second fixed contact point when the buffer member (30, 32, 34) is not pressed through the movable member, the buffer member (30, 32, 34) adjusting an operation load applied to the movable member during inversion of the dome shape, wherein the buffer member is a leaf spring interposed between the substrate and the movable member to cover the first fixed contact point, or wherein the buffer member is conductive rubber mounted on the substrate to cover the first fixed contact point, or wherein the substrate includes one of a through hole and an indentation in a portion with which the movable member comes into contact upon the inversion of the dome shape, the first fixed contact point is disposed around the one of the through hole and the indentation, and the buffer member is a leaf spring mounted on the substrate to cover the first fixed contact point and the one of the through hole and the indentation.
