Claims (1)

[Claims for Utility Model Registration] (1) A substrate, an elastic switch means disposed on the substrate, and a press operation element for pressing the elastic switch means, the press operation element being pressed in a downward direction. a central pressing part having a plurality of strips protruding toward the bottom and extending radially toward the periphery from at least the bottom side, being flush with the bottom surface; and a bottom surface of the central pressing part surrounding the central pressing part. and an annular rib formed to protrude downward in an annular shape, and the elastic switch means is formed to bulge upward at a position facing the press operation element, and is movable to approximately the center of the lower surface. It is composed of a bulging part on which a contact is arranged, and an elastic annular projection that projects upward in an annular shape on the upper surface of the bulging part, and the elastic annular projection is pressed by a central pressing part. At the same time, the shoulder portion of the bulging portion is pressed by the annular rib, thereby causing the movable contact to be separated from the pair of movable contacts fixed to the substrate at a predetermined distance. A switch device characterized by uniformly contacting the fixed contacts of the switch. (2) The switch device according to claim 1, wherein the upper surface of the elastic annular protrusion of the elastic switch means is provided with a protrusion that protrudes upward and has a height that does not protrude above the upper end of the elastic annular protrusion. . (3) A substrate, an elastic switch means disposed on the substrate, and a press operator for pressing the elastic switch means, the press operator protruding downward and extending at least from the bottom side. a central pressing part having a plurality of strips extending radially toward the periphery while being flush with the bottom surface thereof; The elastic switch means is formed of an annular rib formed in a bulge facing upward at a position facing the press operation element, and has a bulge with a movable contact disposed approximately in the center of the lower surface. and a protrusion formed to protrude upward at approximately the center of the upper surface of the bulge, and when the protrusion is pressed by the central pressing part,
At the same time, the shoulder portion of the bulge is pressed by the annular rib, thereby causing the movable contact to be connected to a pair of fixed portions fixed to the substrate at a predetermined distance from the movable contact. A switch device characterized in that the contact points are brought into uniform contact.
