摘要： The invention relates to a movable contact used for a sheet having a movable contact for example used for an electronic device such as a mobile phone and provides a movable contact that realizes, even when having a smaller size, a required pressing force and a favorable click touch response. To realize this, a part surrounded by a conical circumferential edge in which a circular outer circumference edge when seen from the upper side has an inclined surface forms a spherical surface-like section that swells in an upward direction. Both ends of the circle having an identical distance to center line of the circle are straightly cut off. Then, parts at which these straight cut edges intersect with the circular edges are chamfered to have a circular arc to provide a movable contact having a substantially oval shape having circular arc corners.

摘要： A movable contact includes a dome portion having substantially a dome shape and a periphery, and four projections provided on a concave surface of the dome portion. The periphery of the dome portion has substantially an oval shape having a longitudinal direction. The periphery having two linear peripheries in parallel with the longitudinal direction and two arcuate peripheries connected to the two linear peripheries at four corners. The four corners are arcuate. Two diagonal lines connecting the four corners intersect at a center of the dome portion. The four projections are located on the two diagonal lines at identical distances from the center. The movable contact contacts a fixed contact stably with an excellent click feeling on a pushing operation.
