Title:
可動接点
Document Type and Number:
Japanese Patent JP4788576
Kind Code:
B2
Abstract:
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.
