摘要： A switch sheet and switch utilizing the switch sheet are provided, wherein the switch sheet utilizes a dome shaped spring, and is structured such that the dome shaped spring can be definitively clicked in the center part and operate effectively even when the dome shaped spring is miniaturized. In addition to having long-lasting, superior durability, this switch sheet provides an improved click ratio enabling miniature devices with a good clicking sensation to be achieved. This switch sheet comprises a dome shaped spring, resin sheeting adhered to the external surface of this dome shaped spring via an adhesive agent, and a rigid member positioned on the outside of this resin sheeting, having a downward facing protrusion part formed to oppose the center part of said dome shaped spring.

摘要翻译： 提供了利用开关片的开关片和开关，其中开关片采用圆顶形弹簧，并且构造成使得圆顶形弹簧可以在中心部分被确定地点击并且即使当圆顶形弹簧小型化时也能有效地工作 。 除了具有持久，优异的耐用性之外，该开关片提供了改善的点击率，使得能够实现具有良好咔嗒声的微型装置。 该开关片包括圆顶形弹簧，通过粘合剂粘附到该圆顶形弹簧的外表面的树脂片和位于该树脂片的外侧的刚性构件，具有形成为与中心相对的向下的突出部 所述圆顶形弹簧的一部分。
