| 摘要 |
<p>The present invention relates to a metal dome switch, and more particularly, to a metal dome switch connecting upper pattern units (41, 42) and lower pattern units (21, 22a, 22b) which are composed of conductive conductors between non-electric insulation members (300) in a thin plate shape. An insulating member (500) is bonded to the upper pattern unit by manufacturing a penetration hole (51) which is greater than the external diameter of a metal dome (600). The metal dome (600), consisting of an electric contact point on the upper pattern unit (42) by elastic deformation under external pressure, is located inside the penetration hole (51) of the center part of the insulation member (500). The external diameter part of the metal dome (600) is located on the upper pattern unit (42) to be electric contact point. An insulation member (700) protects the inside to entirely cover the insulation member (500) and the upper side of the metal dome (600).</p> |
