| 121 | MOVABLE CONTACT, SHEET HAVING MOVABLE CONTACT, AND SWITCH APPARATUS USING THE SAME | US11843828 | 2007-08-23 | US20080210534A1 | 2008-09-04 | Minoru Karaki; Akira Kamie; Nobumasa Nakao |
| 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. | ||||||

| A keyboard assembly includes an insulative substrate upon which are carried a plurality of conductive paths. Respective portions of the paths are selectively bridged upon depression of a dome-shaped conductive resilient contact element. A pair of space-opposed regions of the dome's marginal portion are deformed downwardly away from its apex so as to constitute a pair of space-opposed feet. The feet have a complex shape which leads to high lifetime of the dome. Preferably, the feet rest on corresponding conductive pads, and the pad pairs for adjacent domes may be differently oriented so as better to accommodate the passage of leads between those domes. Leads on the substrate passing beneath dome edges desirably are depressed into the substrate. Overlying the domes in a completed assembly is a layer of deflectable insulating material that is adhesively affixed to the substrate and to the domes; the latter includes an aperture in registry with each dome but of a diameter smaller than the width of such dome. Advantageously, the adhesively-coated layer also is utilized for the purpose of picking up individual domes from a magazine and transferring them to their assigned positions on the substrate. | ||||||
