Description
そして、第1のシート51を介して可動接点53が押圧されて、膨出部が反転することで可動接点53が中央固定接点60と当接して電気的な接続が行なわれる。
このため、操作ストロークを延ばすために円形ドーム状の可動接点の外周に脚片を突設してストロークを伸ばす構造のスイッチが提案されている(例えば、特許文献2参照)。
このため、可動接点の外周に脚部を突設して操作ストロークを延ばすことが考えられるが、押圧操作でこの脚部の根元にクラックが入りやすく、長寿命対応が難しいという問題があった。
また、第3の解決手段として、上記の解決手段に記載の可動接点体を、隣接する前記可動接点体の前記開口部を対向させて複数個粘着シートに貼付け、この粘着シートの粘着面側を剥離シートで覆った構成とした。
また、下端周縁部の外周を構成する円中心と膨出部の頂部とを互いに異ならせたことから、スカート部の下端周縁部の外周の曲率中心と、半径の設定を変えるだけでストロークの調整ができる。
また、第1又は第2の解決手段に記載の可動接点体を、隣接する可動接点体の開口部を対向させて複数個粘着シートに貼付け、粘着シートの粘着面側を剥離シートで覆ったことから、シートスイッチの狭ピッチ化が図れ、剥離シートで覆われた粘着シートによって取扱い及び組立を簡単にできる。
尚、周辺固定接点2bは一対対向して配置しても、櫛歯状もしくは環状に連結して配置しても良い。また、周辺固定接点2bは一対対向せずに一ヶ所だけに配置するようにしても良い。
また、粘着シート5の代わりに、可動接点体3の上面を可動接点体3よりも細幅の帯状粘着テープで個々の接点上に個別に貼付けるようにしても良い。

Claims (4)
- 固定接点上へ載置される下端周縁部と、この下端周縁部から所定の角度で立ち上がるスカート部と、このスカート部に連続する反転可能なドーム状の膨出部とを備え、前記スカート部は、対向する一方の両側面部が平行に切り欠かれることにより両側面部に開口部を有する長尺状に形成され、前記下端周縁部は前記膨出部を挟んで対向する位置にそれぞれ形成され、且つ、前記下端周縁部の外周を構成する円中心と前記スカート部に連続するドーム状の膨出部の頂部とを互いに異ならせ、前記スカート部の下端周縁部を、前記スカート部に連続するドーム状の膨出部の中心によって形成される円弧よりも大きな円弧状に形成し、前記膨出部を挟んで対向する円弧状の下端周縁部の延在方向における両端部を前記固定接点上に載置させ、円弧状の各前記下端周縁部の延在方向における両端部間に位置する中間部を、前記固定接点の載置面を含む平面から離間させるように形成したことを特徴とする可動接点体。
- 請求項1記載の可動接点体を、つなぎ桟を介して帯状の金属板に複数個連結し、前記つなぎ桟を前記スカート部の前記開口部及び下端周縁部の両端部以外の外周部に形成したことを特徴とする可動接点体。
- 請求項1記載の可動接点体を、隣接する前記可動接点体の前記開口部を対向させて複数個粘着シートに貼付け、この粘着シートの粘着面側を剥離シートで覆ったことを特徴とする可動接点体。
- 請求項1記載の可動接点体と、この可動接点体の下端周縁部が載置される周辺固定接点と、この周辺固定接点に隣接して配設され、前記可動接点体のドーム状膨出部の頂部下面が接離可能に対向して配置された中央固定接点とを備えたことを特徴とする押釦スイッチ。
